Answer:
100 minutes
Step-by-step explanation:
Let x = # of minutes
Company A: y = 21 + .17x
Company B: y = 26 + .12x
Set the equations = to each other.
21 + .17x = 26 + .12x
.17x = 5 + .12x
.05x = 5
x = 100
Answer:
x=20
Step-by-step explanation:
2(x+10)=60
distribute 2 by multiplying numbers in parenthesis
2x+20=60
subtract 20 from both sides
2x=40
divide both sides by 2

Answer:
17
Step-by-step explanation:
Let the smaller number = x
Let the larger number = y
y = 2x + 8
y - x = 25 Add x to both sides
y = x + 25 Substitute this into the first equation
x + 25 = 2x + 8 Subtract 8 from both sides
x + 25 - 8 = 2x Combine
x + 17 = 2x Subtract x from both sides.
17 = 2x - x Combine
17 = x
