Marcy drew the following triangles to show that LMN PQR.Does Marcy's drawing indicate that LMN PQR?

How many miles would it take for the two plans to be the same.

Answers

Let's assume

total miles is x

case-1:

initial fee is $ 65

additional rate is $0.20 per mile

so, the total cost = initial fee + x* additional rate

C=65+0.20x

case-2:

initial fee is $ 0

additional rate is $0.70 per mile

so, the total cost = initial fee + x* additional rate

C=0+0.70x

Since, both costs are same

so, we can set them equal

and we get

65+0.20x=0+0.70x

now, we can solve for x

65=0.70x-0.20

65=0.50x

x=130

so, it would take 130 miles to drive for the two plans to cost the same .......Answer

B - 60 Shirts

15 percent is 3/20 of a whole, meaning that 1/20 of a whole would be 3. Then, multiply the 1/20 by its denominator.

3*20= 60

Your answer is B= 60 shirts

8/11(n-10)=64 I need to show my work to

Answers

Hope you understand it and see what I did.
so first you multiply 8 over 11 and n and you get: 8/11n
then you multiply 8 over 11 and 10 and you get 80 over 11 but then you have to make it a mixed fraction which is 7 1 over 2. then you end up with this equation: 8 over 11n X 7 1 over 2 equals 64. Then im stuck.. because im in 8th grade and in Pre Algebra so im just now learning this.. xD but maybe you can get it from there.
