3. Brenda, 150 lbs., has an office job and spends about 6 hours a day at her computer, burning 102 calories per hour.
She recently had a shelf installed in her office, and can

LIKELY burn?

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8
