Answer:
C = km
k = 95
C = 665
Step-by-step explanation:
Calories burned varies directly to miles run.
Let
C = calories burned
m = miles
C = km
Dustin burns 190 calories for every 2 miles he runs
C = 190
m = 2
C = km
190 = k2
Divide both sides by 2
k = 95
equation for the direct variation.
C = km
Find how many calories Dustin will burn after running 7 miles.
C = ?
m = 7
k = 95
C = km
C = 95 × 7
= 665

Answer:
Step-by-step explanation:
58.6% of the total income is 17,000
let x represent the total income
58.6%(x) = 17,000...turn ur percent to a decimal
0.586x = 17,000
x = 17,000 / 0.586
x = 29010.238 rounds to 29,010.24 <== total yearly income
check...
58.6% of 29,010.24 = 17,000
0.586(29,010.24) = 17,000
17,000 = 17,000 (correct)
