Answer
Find out how many months will it take for Jeff to weigh the same as Darius .
To prove
As given
Jeff and Darius are trying to gain weight for the football team.
Jeff weighs 120 pounds and is gaining ten pounds per month.
Darius weighs 150 pounds and is gaining 4 pounds per month.
m = represented the number of months will taken by the Jeff to weigh the same as Darius .
Than the equation become in the form
120 + 10m = 150 +4m
150 - 120 = 10m - 4m
30 = 6m

m = 5 months
Therefore in 5 months will it take for Jeff to weigh the same as Darius.
Answer:
let x=rate of the rowing team in still water
x+4=rate of the rowing team with current
x-4=rate of the rowing team against current
travel time=distance/rate
..
90%2F%28x%2B4%29=10%2F%28x-4%29
90x-360=10x+40
80x=400
x=5 rate of the rowing team in still water=5 mph
Answer:
13
Step-by-step explanation:
2(5) = 10, +3 = 13 years old,, just use order of operations and plug in jillians age for the x
Answer:
B)
Step-by-step explanation:
A function is when every input has one output.
Easiest way is to do the "vertical line test" and "horizonal line test."
Basically you draw a vertical line and a horizontal line.
If either line passes through more than one point, then it is not a function.
The only one that passes them is B, the line.
So, We Have A Rate That We Need To Simplify. We Have:
88 students for every 4 classes
So, We Need To Simplify This Rate. In Order To Do This, We Need To Change Is To A Fraction. It Is:
88 students
---------------
4 classes
Now, We Have To Simplify. We Can Do That By Remembering How To Simplify Fractions.
So,
88 ÷ 2 = 44 ÷ 2 = 22 students
--- --- ---------------
4 ÷ 2 = 2 ÷ 2 = 1
So, The Unit Rate For 88 Students For 4 Classes Is:
22 Students For One Class
