Answer:
yes
Step-by-step explanation:
Answer:
Step-by-step explanation:
y = 25x +100
y- is the total money spent on the phone
x-is the number of months you had service
the relationship between x and y is proportional ( if x grows, y grows)
For example: after 2 months you would had payed $100 for the phone + the $25 each of the 2 months. y= 25*2 +100 = $150
Complementary angles = 90
x+y =90
y=x+24
substitute this in to the equation
x+x+24=90
2x+24=90
subtract 24 from each side
2x = 66
divide by 2
x=33
y = 33+24
y=57
Answer: 33, 57
