Answer:
24 is correct answer
Step-by-step explanation:
its a 5:15 ratio, you are finding 8:x
8/5=1.6-> 1.6 x a5 = 24
Answer:
24 plates
Step-by-step explanation:
If she can wash 15 dishes in 5 minutes you just need to figure out how many dished she can washe in 1 minute. so you are gonna divide 15 by 5 and get 3 because 3 times 5 equals 15. so then that means she can wash 3 plates in 1 minute. so if she washed 15 in 5 in 6 minutes she can wash 18 and in 7 minutes she can wash 21 and in 8 minutes she can wash 24. Your just adding 3 to the 15 for every minute.

Answer:
a) - 10
Step-by-step explanation:
The two angles are vertical angles:
Angles that have a common vertex and whose sides are formed by the same lines.
Therefore, set your formula up as following
x+5=2x-5
x + 5 - 2x = -5
-x + 5 = -5
-x = -10

To write the equation of a line in slope-intercept form, there are two things we need: the y-intercept and the slope.
To find the y-intercept using a graph is relatively easy. We are looking to see where the line crosses the y-axis. In this case, that is at the point (0,4).
To find the slope, we need to first find two points that are on the line. I will be using the points (0,4) and (2,5), though you can use any two that you would like. Then, we'll need to use the slope formula (y2 - y1 / x2 - x1).
(5 - 4) / (2 - 0)
1 / 2 = slope
Now that we have the slope and y-intercept, we can simply plug those values into slope intercept form, y = mx + b, where m is the slope and b is the y-intercept.
Therefore, our equation of the line in fully simplified slope-intercept form is y = 1/2 x + 4.
Hope this helps!! :)
Answer:
y = 1/2x + 4
Step-by-step explanation:
Slope-intercept form is: y = mx + b
The slope is 1/2 (mx)
Up 1, Over 2, which is the space between each dot.
The y-intercept is 4 (b)
The point where the line crosses the y-axis.
y = 1/2x + 4
Hope this is correct for you!
Allison had 18 postage stamps she gave 2/9 of the stamps to her mother and used 1/2 of the remaining stamps to send letters to her friends in Canada how many stamps are left
Answer is 7
step-by-step explanation:
you would do 2/9 times 18 which is 4 you would subtract 18 - 4 which is 14 then you would do 14 / 2 and your answer will be seven

A student is collecting dimes and quarters as a fundraiser for their CAS project. After the first week, they tasked a younger sibling to count them up, who found there to be 211 coins. After taking the coins to the bank, the student was given $37.30. Find how many dimes did the student collect, and how many quarters did the sudent collect?
Answer: [tex]103,108[/tex]
Step-by-step explanation:
Given
There are total of 211 coins
The worth of the coins is [tex]\$37.30[/tex]
Suppose there are x dimes and y quarters
A dime is equivalent to 10 cents and quarter is equivalent to 25 cents
[tex]\therefore x+y=211\quad \ldots(i)\\\Rightarrow 0.1x+0.25y=37.30\\\Rightarrow x+2.5y=373\quad \ldots(ii)[/tex]
Solving (i) and (ii) we get
[tex]x=103,y=108[/tex]
Therefore, student collects 103 dimes and 108 quarters.
What is the simplest form of b/bc ??
Solve for w
5w.+ 36°
Зw
Answer:
w=18
Step-by-step explanation:
So, lets go over what we know:
A line is 180 degrees.
5w+36 is the first part of the line.
3w is the other part of the line.
So 5w+36 and 3w is 180 degrees.
We can write this as:
5w+36+3w=180
Combine the 5w and 3w:
8w+36=180
Subtract 36 from both sides:
8w=144
Divide 8 from both sides to get w alone:
w=144/8
=
w=18
Hope this helps!

Part A: Factor 3x2a2 − 5xa2 − 2a2. Show your work. (4 points)
Part B: Factor x2 − 10x + 25. Show your work. (3 points)
Part C: Factor x2 − 81. Show your work. (3 points)
Answer:
Answer is in bold.
Step-by-step explanation:
Factor 3x2a2 − 5xa2 − 2a2.
3x2a2 − 5xa2 − 2a2=
a2(3x2 − 5x − 2)=
a2((x-2)*(x+(1/3)))
Part B: Factor x2 − 10x + 25.
x2 − 10x + 25.= (x-5)*(x-5)
Part C: Factor x2 − 81.
x2 − 81=(x-9)*(x+9)

There are 2.54 Centimeters in 1 inch . THere are 100 Centimeters in 1 meter
To the nearest Meter, how many meters are in 360 inches
Answer:
9.144meters
Step-by-step explanation:
Given data
We are expected to perform unit conversion in this problem
2.54cm is equivalent to 1 inch
100cm equal to 1 meters
360 inches to cm will be
=360*2.54
= 914.4cm
914.4cm to meters will be
=914.4/100
=9.144meters

Properties of Triangles HELP
Answer:
x = 14
m<D = 57
Step-by-step explanation:
All triangle interior angles add up to 180.
<D and <E are congruent because of the congruent legs which makes them congruent angles:
4x + 1 + 4x + 1 + 5x - 4 = 180
13x - 2 = 180
13x = 180 + 2
13x = 182
x = 14

quentin is going to buy a pair of pants that cost $32.50. he has a coupon for 20% off the price of one item and another coupon for $5.00 off the price of one item. he can only use one coupon. which coupon should quentin use to save the most money
Answer:
20% coupon
Step-by-step explanation:
20% of 32.50 = 6.5
32.50 - 6.50 = 26
32.50 - 5 = 27.50
26 is less than 27.50, therefore, the 20% off coupon should be used to save him $1.50.

Answer:
x = 94
Step-by-step explanation:
[tex]x + (\frac{1}{2}x + 39) = 180[/tex]
1.5x + 39 = 180
Subtract 39 from each side.
1.5x + 39 - 39 = 180 - 39
Simplify.
1.5x = 141
Divide each side by 1.5.
1.5x ÷ 1.5 = 141 ÷ 1.5
x = 94

Step-by-step explanation:
If I think of a number halve it and subtract 2 results is 10.write equations and solve it please
Answer:
24
Step-by-step explanation:
let 'x' = number
x/2 - 2 = 10
add 2 to each side to get:
x/2 = 12
cross-multiply to get:
x = 24
Answer:
The equation is (x/2) - 2 = 10The equation solves to x = 24============================================================
Explanation:
x = the number you think of
x/2 = the result after taking half of that number
(x/2) - 2 = subtract 2 from the previous result
(x/2) - 2 = 10 is the equation to solve
Solving said equation gets us...
(x/2) - 2 = 10
x/2 = 10+2 ... adding 2 to both sides
x/2 = 12
x = 12*2 ..... multiplying both sides by 2
x = 24
Notice how we basically undo everything applied to x. First we divided by 2, then we subtracted 2. So we follow that order in reverse to undo the "minus 2" (ie add 2 to both sides). Then we undo the division to multiply both sides by 2 to end up with the answer x = 24
-----------------
Let's check that answer:
x = 24
x/2 = 24/2 = 12 ... result after taking half of x
(x/2) - 2 = (12)-2 = 10 ... result after subtracting two
We end up with 10 as your teacher mentioned, so it confirms that x = 24 is the answer.
------------------
Here's another way to check:
(x/2) - 2 = 10
(24/2) - 2 = 10
(12) - 2 = 10
10 = 10
We end up with the same thing on both sides, so x = 24 is confirmed.
Thirty students were asked what their favorite number from 1 through 9 was. The results were 8 students said 3. 6 students said 4, 9 students said 7, and 2 students said 9. What is the experimental probability that the number 7 was picked as the favorite number?
Answer:
3/10
Step-by-step explanation:
From the question, we have the total number of sampled students as 30
9 students said 7 was their favorite
So the experimental probability that we have 7 picked as the favorite number will be the number of respondents who chose 7 as their favorite divided by the total number of respondents
We have this as;
9/30 = 3/10
