Answer:

A.78

Step-by-step explanation:

\frac{30}{25sec} -----> \frac{78}{65sec} (scale by 2.6)

You cant get the answer by following these steps.

1. To find out how much we must increase with our scaling we must divide the denominators.

\sqrt[25]{65}= 2.6

2. Then, we do the scaling. Multiply the numerator and the denominator by 2.6.

num- 30 x 2.6= 78.0 (DONT FORGET UR DECIMALS)

dem- 25 x 2.6 = 65

3. Now you have your answer and all you need to do is show it in fraction form as seen below the words "step by step explanation"

Gook luck and pls give brainlist

11x = 77

x = 7

3x + 11 = 3(7) + 11 = 32

8x + 2 = 8(7) + 2 = 58
