Stefan requires 6 hours to wash the cars by himself. In one hour he washes 1/6 of the cars. Misha can wash the cars by herself in 5 hours. In 1 hour she can wash 1/5 of the cars.
Stefan has 2.5 hours to wash the cars as he has to go to the football game. In 2.5 hours he has washed (1/6)*2.5 = 5/12 of the cars. This leaves 1 - 5/12 = 7/12 of the cars for Misha to wash. As she washes cars at the rate of 1/5 per hour, it would take her (7/12)/ (1/5) = (5*7)/12 = 35/12 hours to wash the remaining cars.
35/12 hours is equal to 175 minutes or 2 hours 55 minutes.
Misha finishes washing the cars in 2 hours and 55 minutes after Stefan leaves.
It’s 6 with a remainder of 4. So what we’re doing here is dividing 32 by 5. It’s pretty simple. Hope this helps!

<h3>
Solution (4, -12)</h3>
<em>None of the listed choices are a solution</em>
Step-by-step explanation:
y = 4x - 28
y = 1.5x - 18
Set the equations equal since both equal y
4x - 28 = 1.5x - 18
Subtract 1.5x from both sides
2.5x - 28 = -18
Add 28 to both sides
2.5x = 10
Divide both sides by 2.5
x = 4
---------------------
use x= 4 in either equation
y = 4x - 28
y = 4(4) - 28
y = 16 - 28
y = -12
--------------------
Solution (4, -12)

Answer :
I GOT CHU !!!!: )
Step-by-step explanation:
1. One way they are similar is that both of them have the same angles due to the process of dialation one is smaller than the other another way i can tell the two shapes are similar is that they are both on the x and y axis and that they've both been dialated one unit.
sorry i have to go but i gave you number one
HOPE THIS HELPS YOUUU !!!!!
