Joel is participating in the Jogathon. He wants to help the school raise as much money as possible. For every lap he runs, he earns money from his sponsors. He wants to run at least 30 laps. He has already run 10 laps and he has 20 more minutes to run. How many more laps will he need to meet or exceed his goal? Define the variable.
Write and solve the inequality that represents the situation.

entering that problem on the tube might get you an answer

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.

hope this !

let me know

if you are looking for the unit rate then the answer would be 9 because unit rate is distance divided by time.
