Kyle is working out at his local gym. He burns 150 calories for every 10 minutes he runs on the treadmill and 10 calories for every minute he uses a jump rope. He burns 430 calories over 37 minutes of working out.

Okay s a team Match members is the last in

00:04

the series of arduous painful word problems At least this

00:08

siri's here we go Kyle is working out of his

00:10

local gym yet again he burns on unfit to galleries

00:14

for every ten minutes he runs on the treadmill and

00:16

ten calories For every minute he uses a jump rope

00:21

He burns four hundred thirty calories over thirty seven minutes

00:23

of working out If our represents the amount of time

00:27

he runs on the treadmill and j is the amount

00:29

of time he jumps rope both measured in minutes Here's

00:32

they're giving us the standard unit there which of the

00:35

following systems of equations accurately represents kyle's workout We're going

00:41

to need two equations to solve this pumped up problem

00:44

one for each arm The only units we have our

00:47

calories in minutes so start by making an equation about

00:49

calories The problem states kyle burns hundred fifth galleries for

00:52

every ten minutes he runs So he burns ah hundred

00:55

fifty divided by ten or fifteen calories a minute there

00:58

while running If he burns ten calories a minute jumping

01:02

rope and four hundred thirty calories in total Well then

01:05

we got everything we need for a toned and sculpted

01:07

body of an equation That's fifteen are plus ten j

01:10

is for thirty right there That's it The other equation

01:12

deals with time We'll kyle runs for our minutes and

01:15

jumps for j minutes Kyle is motivated for a solid

01:18

thirty seven minutes so our plus j is thirty seven

01:21

That's it you got two equations Fifteen are plus ten

01:24

jay's for thirty and our plus jay's thirty seven it's

01:26

be good work I'll make sure you wipe down the

01:29

calculators you use You know when you're done with them 00:01:31.934 --> [endTime] we don't want to share your sweat
