1) How many weeks will Jake and Seth be equal? set the equations equal to each other and solve for x:

5x + 85 = 20x + 40

45 = 15x

x = 3 weeks

2) How much money will that be? plug x = 3 back into the equation to solve for y:

Jake: 5(3) + 85 = $100
Seth: 20(3) + 40 = $100

answer is $100

A running back is having a great day on the football field. It’s only the third quarter, and he’s already rushed for 203 yards.

Naddik [55]

Answer:

He needs to gain more than 26 yards in order to break his record

Step-by-step explanation:

Let y stand for the number of yards he’ll have to gain. The sum of y plus the number of yards he already has (203) must be greater than 229 in order for him to break the record.

203 + y > 229 Set up the inequality.

203 − 203 + y > 229 − 203 Subtract 203 from both sides of the inequality.

y > 26
