Do we have a model, or anything to go by?
Answer:
Step-by-step explanation:
128 - 6x - 39 + 5x = -31 + 9x
89 -x = -31 + 9x
10x = 120
x = 12
m<QRS= -31 + 9(12)= -31 + 108= 77
m<TRS= -39 + 5(12)= -39 + 60= 21
m<QRT= 128 - 6(12)= 128 - 72 = 56
Answer: $100
Step-by-step explanation:
Percent Formula: P% * X = Y
The first step is to convert the percent to decimal: 40% -> .4
Then, multiply the original number by the decimal: 250 * .4 = 100
we have the following:
solving for b:
therefore, the answer is 16
