Answer: 4'6 2'4
Step-by-step explanation:
Ravi is 8 years older than nastasha the sum of their ages is 42 find their ages
Answer: Natasha is 17 and Ravi is 25
Step-by-step explanation:
Let n = Natasha’s age and r = Ravi’s age
We can write an equation then substitute: 42=n+r
We know that Ravi is 8 years older than Natasha, so Ravi’s age is equal to n+8. We can substitute that in, so 42= n+(n+8)
Simplify:
42=n+(n+8)
42= 2n+8
42-8=2n+8-8 (subtract 8 from both sides to isolate n)
34=2n
34/2=2n/2 (divide both sides by two)
17=n
Natasha is 17, and Ravi is 8 years older. 17+8= 25, Ravi is 25. You can double check by adding 25 and 17 together, which brings you back to 42 :]

Write the equation in standard form. Then factor the left side of the equation.
2x2 + 7x = 15
A. (2x – 5)(x + 3) = 0
B. (2x + 3)(x + 5) = 0
C. (2x – 3)(x + 5) = 0
D. (2x + 5)(x – 3) = 0
Answer:
C. (2x – 3)(x + 5) = 0
Step-by-step explanation:
The equation in standard form should be 2x^2 + 7x - 15 = 0
Factored the expression is (2x - 3)(x + 5).
In order to find the factored portion, you must look for factors of the front number (2) to use in the front of the parenthesis and factors of the last number (-15) to go in the end.
When we use the ones that we have above, it distributes to the overall end result.
(2x - 3)(x + 5)
2x^2 - 3x + 10x - 15
2x^2 + 7x - 15
If equation is x + y = 3 and x - y = 7 then the value of x will be?
A) 0

Answer:
x = 5
Step-by-step explanation:
Add the equations
x + y = 3
x - y = 7

2x = 10
Divide both sides by2
x = 5
Note: for the equations in the question,
none of the given answers are correct.

Averigua el número que cumple la siguiente condición: si se multiplica su sucesor por el número disminuido en 3 unidades se obtiene 77
Answer:
X=10
X=-8
Step-by-step explanation:
(x+1)*(x-3)=77
x²-3x+x-3=77
x²-2x-3=77
x²-2x-3-77=0
x²-2x-80=0
(x-10)*(x+8)=0
x-10 = 0
x=10
x+8=0
X=-8
The two possible numbers that satisfy the given equation model are -8 and 10.
What is a expression? What is a mathematical equation? What is Equation modelling ?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
Given is the successor of a number, when multiplied by the number decreased by 3 units, 77 is obtained.
Assume the number to be [x]. Its successor would be [x + 1]. Then, we can write -
(x + 1)(x - 3) = 77
Refer to the graph attached. The [x] - intercepts the solution. We get -
x = - 8
x = 10
Therefore, the two possible numbers that satisfy the given equation model are -8 and 10.

Write an equation for the total water usage, U, at the park this year in terms of x, the number of special events the park has hosted
Answer:
U = 16206 + 22.2x
Step-by-step explanation:
This year, water usage has increased by 20% for both regular days and special events.. Write an equation for the total water usage, U, at the park this year in terms of x, the number of special events the park has hosted
Solution:
Last year regular usage of water was 13505 gallons, where as it was 18.5 gallons per special event. Let us assume that there were x special invents, hence:
The total usage for last year = 13505 + 18.5x
This year, the total usage (U) increased by 20%, hence:
Total usage for this year (U) = total usage for last year + 20% of total usage for last year
U = (13505 + 18.5x) + 0.2(13505 + 18.5x)
U = 13505 + 18.5x + 2701 + 3.7x
U = 16206 + 22.2x

Alternate Interior Angles
Step-by-step explanation:
They are alternate interior angles. The reason this works is because 4 is opposite to 3, meaning that 4 is equivalent to the value of (180-Angle3)
Meanwhile 6 is equivalent to (180-Angle5). Angle 5 is the same value is Angle 4.

A garden table and a bench cost 816 combined. The garden table costs 84 less than the bench. What is the cost of the bench?
Answer:
366
Step-by-step explanation:
A garden table and bench cost 816 when combined together
The garden table cost 84 less than the bench
Therefore the price of the bench can be calculated as follows
x + (x+84)= 816
2x+84= 816
2x= 816-84
2x= 732
Divide both sides by 2
x= 732/2
= 366
Hence the price of the bench is 366

Suppose that of 2000 students, 1100 take math, 500 take science, and 300 students take both math and science. What is the probability that a student selected at random takes math or science?
Answer:
4/5
Step-by-step explanation:
Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.
probability that a student selected at random takes math or science = probability a student takes maths + probability a student takes science
probability a student takes maths = number of maths students / total number of students
probability a student takes science = number of science students / total number of students
(500 / 2000) + (1100 / 2000) = 1600/2000 = 4/5

In a certain video game, players earn bonus points after finishing a
level. The number of bonus points is based on how many seconds, t,
it takes the player to finish the level. The game uses the expression
-5.5 + 500+ 0.9t + (1 - 1.9t to determine the number of bonus points. .
Zahara finishes a level in 201 seconds. How many bonus points does she earn?
Answer:
If Zahara finishes a level in 201 seconds, she earns:
294.5 pointsStep-by-step explanation:
To identify the number of points that Zahara obtained when she finished a level in 201 seconds, you must use the given expression:
-5.5 + 500+ 0.9t + (1 - 1.9t)Where:
t = time in seconds.As Zahara took 201 seconds to finish a level, we're gonna replace this value in the equation:
-5.5 + 500+ 0.9t + (1 - 1.9t)-5.5 + 500+ 0.9(201) + (1 - 1.9[201]) (we're not use the unit "seconds", because we don't need it in this calculation)-5.5 + 500+ 180.9 + (1 - 381.9)-5.5 + 500+ 180.9 - 380.9 (You can organize the numbers is you want)500 + 180.9 - 380.9 - 5.5294.5 pointsAs you can see, Zahara obtains 294.5 points if she finishes the level in 201 seconds.

There are four sixth graders and seven seventh graders in Elsa's chess club. Two members of the club will be chosen at random to attend a tournament with several other chess clubs. Elsa is using simulation to determine the experimental probability of randomly selecting two sixth graders. So, she places four red discs (to represent the sixth graders) and seven blue discs (to represent the seventh graders) in a bag. She randomly selects one disc from the bag, records the color, keeps the disc out, selects another disc and records it, and then returns both discs to the bag. Elsa does this twenty-five times. Her results are shown in the table below.

Answer:

The values will be equal in 10 years.
Step-by-step explanation:

There are two ways to do this problem. I'll do it the simplest way -- which will benefit you most if you are about to take a physics class.
Follow these observations.
The difference of speed of these two cars is 70 - 65 = 5 mphThe distance travelled by the first car before the second one starts is 65 miles in 1 hour. That comes about because Tom goes 65 miles before Michelle even starts. She starts exactly 1 hour after Tom and he has gone 65 miles in that time.She is going faster, but he is still moving. That's what makes the problem hard.Fortunately, you don't have to figure that out. You have all the information you need.Solution
Time it takes to Catch Tom = distance to be made up / difference in speed
Distance to be made up = 65 miles
Difference in speed = 5 mph
Time taken for michelle to catch Tom = t
t = 65/5
t = 13 hours.
Solution Two
The distance is the same when Michelle catches Tom
d = r*t
Michelle's rate = 70 mph
Michelle's time = t
Tom's rate = 65
Tom's Time = t + 1
70 * t = 65(t + 1)
70 * t = 65*t + 65
70*t - 65*t = 65
5t = 65
t = 65/5 = 13
In thirteen hours, Michelle will catch Tom

One house increases by 10000 the other decreases by 5000. You could do it using the first method above, but in this case the second is actually easier.
Juan: 200000 + 10000*t
Tia : 350000 - 5000t
When will the be equal (at what price and when?).
200000 + 10000t =350000 - 5000t Divide by 1000
200 + 10t = 350 - 5t Add 5t to both sides
200 + 10t + 5t = 350 Combine
200 + 15t = 350 Subtract 200 from both sides
15t = 150 Divide by 15
t = 150/15
t = 10 years
