Answer:
They rented 7 small cars and 2 large cars.
Step-by-step explanation:
Since it went 8 floors in 6 seconds you divide. 8/6 is 1.333 or 1 1/3 floors per second. Hope this helps.
-2z - xy = z + 7
You are solving for x. Note the equal sign. What you do to one side, you do to the other. Isolate the x.
First, add 2z to both sides
-2z (+2z) - xy = z + 7 (+2z)
Simplify. Combine like terms
-xy = z + 2z + 7
-xy = 3z + 7
Completely isolate the x. Divide -y from both sides
(-xy)/-y = (3z + 7)/-y
x = (3z + 7)/-y
Simplify
z = (3z + 7)/(-y) is your answer
hope this helps
Not really, is this a rhetorical question? lol
