Answer:
The measure of the complement is 30°
Step-by-step explanation:
we know that
Two angles are supplementary if their sum is equal to 180 degrees
Two angles are complementary if their sum is equal to 90 degrees
Let
x -----> the measure of an angle
we know that
180°-x=4(90°-x)
Solve for x
180°-x=360°-4x
4x-x=360°-180°
3x=180°
x=60°
Find the complement
90°-x=90°-60°=30°

-4 between each number
Answer:
6miles/hour
Step-by-step explanation:
Speed = Distance/time
So speed is: 
You will get 6/2 from this so you get 6miles/hour
To find the inverse we swap y and x and solve for y:
x = 9y + 15
x - 15 = 9y
y = (x-15)/9
