Jacob spends 60 minutes in the gym every day doing freehand exercises and running on the treadmill. he spends 30 minutes more running on the treadmill than doing freehand exercises. part a: write a pair of linear equations to show the relationship between the number of minutes jacob does free hand exercises (y) and the number of minutes he runs on the treadmill (x). part b: how much time does jacob spend on doing freehand exercises? part c: is it possible for jacob to have spent 40 minutes running on the treadmill? explain your reasoning.

answer:

the verified one here is a little shaky, this would be the best way to answer it:

part a:

x + y = 60

x - y = 30

part b:

x + y = 60

x - y = 30

add those two

2x/2 = 90/2 x = 45

y = 15

meaning that jacob spends 45 minutes on the treadmill.

part c: no, because he spends 45 minutes and not exactly 40 which would make this incorrect.

step-by-step explanation:

y=3n + 1

step-by-step explanation:

this is wrong because it says the second number is one less and i added one instead

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3
