Complementary angles add up to 90 degrees.
Which means.. the equation is
8x-23+7x-7=90
Combine like terms you should get
15x-30=90
Add 30 on both sides
15x=120
Divide 15 x=8
Plug in 8 to (8x-23)
8(8)=64-23=41
m
8
Reduce the expression, if possibel, by cancelling the common factors
so y=5x on a graph is going to look like a 5/1 slope. X represents days and Y represents miles. So (1,5) means in 1 day Fran runs 5 miles.
Answer:
Step-by-step explanation:
Simplify to get
Find what equals to by taking away 8, .
Divide by 2 to find x,
