$32.50 X .4 = $13, 32.5-13=19.5, 19.5 divided 2 =$9.75
A function is a mapping from a set A to a set B, If, for all a1,a2 in A, where a1=a2, a1 and a2 get mapped to the same b in B
Answer:
see below
Step-by-step explanation:
In the system of equations, x represents the, price to wash a car and y represents the price to wash an SUV.
If the system of equations is graphed in a coordinate plane, the coordinates (x, y) of the intersection of the two lines are the price of the car wash (x) and the price of the SUV wash (y)______.
x=12 and y = 18
x+y = 12+18 = 30
The total cost of 1 car and 1 SUV is $_30____.
5x+4y = 5(12)+4(18) = 60+ 72 =132
The total earnings for hour 3 are $_132_____.
Hey There!
Cross multiply on both sides, with this you will be cross multiplying in order to set the numbers up.
s * 2.4 = 2.4s
2.8 * 6 = 16.8
2.4s = 16.8
Divide s from both sides:
16.8/2.4
<u>The answer is 7 or s= 7</u>
