Answer:
n=135/4z+7
Step-by-step explanation:
Let's solve for n.
4nz+7n−135=0
Step 1: Add 135 to both sides.
4nz+7n−135+135=0+135
4nz+7n=135
Step 2: Factor out variable n.
n(4z+7)=135
Step 3: Divide both sides by 4z+7.
I think the answer is 14x
''Decreased'' means subtract and ''times'' means multiplication so the algebraic expression should be 15 - 2 * p.
A.) Mrs. Walter's car gets 14.4 mpg
b.) Mr. Walter's car gets 15 mpg
c.) Mr. Walter gets the best mpg

I hope this helped you!
First thing you need to know is the measure of the central angle. It is the same as the measure of the arc it intercepts, which is 100 degrees. The formula now is this for the area of a sector:

which comes out to

. If you multiply the pi in you'll get 223.4 or thereabouts.
