Answer:
283.19
Step-by-step explanation:
Find the number in the hundredth place 9 and look one place to the right for the rounding digit 2 . Round up if this number is greater than or equal to 5
and round down if it is less than 5 .
Answer:
283.19
Step-by-step explanation:
So as you should already know, the 2 is the hundreds, 8 is the tenths, and 3 is the ones, but you may not know the ones after it. The number after the little dot (decimal) is a 1 and is called the tenths and the one after is the hundredths and then thousandths and so on. You want to know the hundredths so just keep all of the numbers until you get to the number that is 2 places after the decimal and look at the last number and if its below 5, keep the hundredths the same but if its 5 or over make the hundredths 1 higher. for example 3 stays the same because the next number is below 5. This is how you do rounding with decimals! Please give Brainliest if this helps!

How do you solve -2 = t/3 - 11?
______________________________
1.) Multiply both sides of the equation by 3:[tex]\frac{t}{3}[/tex] × [tex]3=t[/tex][tex]-11[/tex] × [tex]-3=-33[/tex]- We do this because we need to get x alone and separate from fraction from.
Equation at the end of Step 1:
[tex]-6=t-33[/tex]2.) Add 33 to both sides:[tex]-33+33=[/tex] Cancels Out[tex]-6+33=27[/tex]- We do this to cancel out an extra numbers in order to get only x alone with 1 number on the opposite side of the equal.

Addison wants to ride her bicycle more than 80 miles this week. She has already ridden her Bicycle 18 miles. Write an algebraic inequality use to determine the average number of miles m she would need to ride her bicycle each day for six more days to achieve her goal?
Answer:
18 + 6m > 80
Step-by-step explanation:
We are told that:
Addison wants to ride her bicycle more than 80 miles this week.
The inequality representing this sign is given as > (greater than).
Let the number of miles be represented as= m
Hence:
She has already ridden her Bicycle 18 miles.
The algebraic inequality use to determine the average number of miles m she would need to ride her bicycle each day for six more days to achieve her goal is given as:
18 + 6 ×m > 80

You go for a run on monday you run 2.41Km on tuesday you ran the same distance how far did you ran altogether
Answer: 4.82 km
Step-by-step explanation:
You went for a run on Monday.
You then went on a run on Tuesday as well. On this day you ran 2.41 km and it is said that you ran the same distance on both days which means you ran for 2.41 km on Monday as well.
The total distance you ran is therefore:
= 2.41 + 2.41
= 4.82 km
What does the Pythagorean theorem state?
Answer:
Step-by-step explanation:

Answer:
Solve the parenthesis
Step-by-step explanation:
In the order of operations (PEMDAS), you would solve what's in the parenthesis first. So you would add 5 and 4, then multiply that by 3 to get the correct answer. Hope that helps!
In the first week of July, a record 1,120 people went to the local swimming pool.In the second week, 100fewer people went to the pool than in the first week. In the third week,140 more people went to the pool than in the second week. In the fourth week, 208 fewer people went to the pool than in the third week. What is the percent decrease in the number of people who went to the pool over these four weeks?
Answer:
15%
Step-by-step explanation:
Given that:
Number of people who went to swimming pool in the first week = 1120
In second week, there are 100 fewer people, so
Number of people who went to swimming pool in the second week = 1020
In third week, there are 140 more people, so
Number of people who went to swimming pool in the third week = 1160
In fourth week, there are 208 fewer people, so
Number of people who went to swimming pool in the fourth week = 952
To find:
Percentage decrease in the number of people who went to the pool over the four weeks?
Solution:
Initial value = 1120
Final value = 952
Decrease in the value = Final value - Initial value
Decrease in the value = 1120 - 952 = 168
To find the percentage, we need to take the initial value in the consideration.
Therefore, percentage decrease is:
[tex]\dfrac{Decrease}{Initial\ value}\times 100[/tex]
[tex]\Rightarrow \dfrac{168}{1120}\times 100\\\Rightarrow \bold{15\%}[/tex]

5(x - 1) and 5x - 1
is it equivalent
Answer:
no
Step-by-step explanation:
5(x - 1) = 5x - 5
5x - 1 = 5x - 1
No, it is not equivalent
The required, 5(x - 1) and 5x - 1 are not equivalent expressions.
Let's expand 5(x - 1):
5(x - 1) = 5 * x + 5 * (-1) = 5x - 5
On the other hand, 5x - 1 is already in its simplified form.
As you can see, the expressions 5(x - 1) and 5x - 1 have different forms. The first expression involves distributing the 5 to both terms inside the parentheses, while the second expression is already simplified and cannot be further combined.
For example, if we substitute x = 2 into both expressions, we get:
5(2 - 1) = 5 * 1 = 5
5 * 2 - 1 = 10 - 1 = 9
Since 5 and 9 are not equal, it confirms that the two expressions are not equivalent.

Solving systems of equations using substitution/eliminationSolving systems of equations by graphingTerms/CoefficientsStep-by-step explanation:
Step 1: Define Systems
3x - y = 9
2x - y = 6
Step 2: Rewrite Systems
2x - y = 6
Subtract 2x on both sides: -y = 6 - 2xDivide -1 on both sides: y = 2x - 6Step 3: Redefine Systems
3x - y = 9
y = 2x - 6
Step 4: Solve for x
Substitution
Substitute in y: 3x - (2x - 6) = 9Distribute -1: 3x - 2x + 6 = 9Combine like terms: x + 6 = 9Isolate x: x = 3Step 5: Solve for y
Define equation: 2x - y = 6Substitute in x: 2(3) - y = 6Multiply: 6 - y = 6Isolate y term: -y = 0Isolate y: y = 0Step 6: Check
Graph the systems to verify the solution set (3, 0) is the solution.
The solution set to the systems would be where the 2 lines intersect.
We see that the intersection point is x-intercept (3, 0).
∴ (3, 0) is the solution set to the systems of equations.

Otto is told the average low temperature in January is 16.1∘C cooler than the average low temperature in November. What equation can Otto use to find the average low temperature in January?
Answer:
x - 16.1°C
Step-by-step explanation:
Given that average low temperature in January is 16.1 cooler Than average low temperature in November
Let average low temperature in November = x
Since, average low temperature in January is cooler than average low temperature in November, then, January temperature is less Than in November
Hence,
Average low temperature in January :
[Average low temperature in November - 16.1°C]

Answer:
180 pages in 2 hours
225 pages in 150 minutes
210 pages in 2 hours 20 minutes
Step-by-step explanation:
135 pages : 90 minutes
= 135/90
= 3/2
= 3 : 2
180 pages : 2 hours
180 pages : 120 minutes
= 180/120
= 3/2
= 3:2
60 pages : 30 minutes
= 60/30
= 2/1
= 2:1
108 pages : 2 1/2 hours
108 pages : 180 minutes
= 108/180
= 18/30
= 3/5
= 3:5
150 pages : 1 hour
150 : 60
= 150/60
= 10/6
= 5/3
= 5:3
225 pages : 150 minutes

Bethany can mow her lamily's lawn in 4 hours. Her brother coin can mow the lawn into hoursWhich equation can ve
used to find the number of hours, x, it would take for Bethany and Colin to mow the lawn together?
Answer:
1/x = 1/4 + 1/3
Step-by-step explanation:
In 4 hours Bethany did the whole fraction 1 of the house.
In 1 hour he would do 1/4 of it.
In 3 hours Colin did the whole fraction 1 of the house.
In 1 hour he would do 1/3 of it.
In 1 hour they would both do (1/4 + 1/3)
If it takes both of them x hours to finish 1 whole fraction of the house.
In 1 hour they will both do 1/x
That means that:
1/x = 1/4 + 1/3
