Answer:
a=3/4
Step-by-step explanation:
1. Get 2/3a by itself.
•Turn 1/3 to 2/6 by multiplying 1/3 by 2/2.
•Because you only add and subtract like denominators
This will make it look like:
2/3a - 1/6 = 2/6
Then, add 1/6 to both sides to get 2/3a by itself.
It'll look like this:
2/3a = 3/6
2. Get a by itself.
•Multiply the reciprocal (opposite) of 2/3 to get a alone.
This will look like:
(3/2) • 2/3a = (3/2) • 3/6
a = 18/24
3. Simplify.
Find the largest number that can simplify the equation.
For example, 18 ÷ 3 = 6, and 24 ÷ 3 = 8.
But the largest number you can divide both sides by is 6.
18 ÷ 6 = 3 and 24 ÷ 6 = 4.
3/4.
Question:
A running club keeps track of the number of hours each person has trained for a race and the length of time it takes the person to run the race. A scatter plot is graphed with the x-axis indicating the number of hours a runner has trained and the y-axis indicating the time, in minutes, it took to run the race. The equation y = 60 - 0.5x is used as the line of best fit of the data. What does the slope of the equation represent?
options:
a
Runners will decrease their race time by 2 minutes for every 1 hour they have trained.
b
Runners will increase their race time by 2 minutes for every 1 hour they have trained.
c
Runners will increase their race time by 1 minute for every 2 hours they have trained.
d
Runners will decrease their race time by 1 minute for every 2 hours they have traine
The solution is, 60 minutes is a good prediction of how long it will take Tom to run the 6 mile race.
What is scatter plot?A scatter plot is a type of plot or mathematical diagram using Cartesian coordinates to display values for typically two variables for a set of data. If the points are coded, one additional variable can be displayed.
Here, we have,
We are given the scatter plot which shows the distance he has run and the time it took for each run.
We are asked to determine a good prediction of how long it will take Tom to run the 6 mile race?
One way to predict the time is by drawing a line that best fits the given data.
As you can see, from the line of best fit, the time corresponding to the 6 miles is around 60 minutes.
Therefore, 60 minutes is a good prediction of how long it will take Tom to run the 6 mile race.

The perimeter of a square is 100 feet. What is the length of one of its sides? Explain your work.
Answer:
25
Step-by-step explanation:
to find the perimeter you add up all the sides and since it's a square and squares have all four equal sides
you just divide 100/4=25
4 sides of a square. Each side of a square is equal. You said the perimeter is 100. So if we put it in an equation, lets say S = Side. 4s=100. Now we just divide. s=25
Each side is 25
Thank or brainliest if helpful :D
Explain and answer pls :)
Answer:
first write boys/girls=2/3 then we know there are 24 boys so; 2/3=24/girls .so we have 24×3/2=36= girls number.
