Answer:

Find the ratio of minutes to miles, 4:1. Multiply 7.5 by 4.

Step-by-step explanation:

Given

Minutes: 10 || 16 || ? || 48

-----Miles: 2.5 || 4 || 7.5 || 12

Required

Which statements solve for the missing value?

First, we need to calculate the ratio of minutes to mile

$Ratio = \frac{Minutes}{Mile}$

When minutes = 16; mile = 4

So, we have:

$Ratio = \frac{16}{4}$

$Ratio = 4$

Next, we multiply the ratio by 7.5

$Minutes = Ratio * 7.5$

$Minutes =4 * 7.5$

$Minutes = 30$

<em>Hence, option B answers the question.</em>

Answer:

D. $\frac{{7}^{11} }{ {4}^{11} }$

Step-by-step explanation:

$( \frac{7}{4}) {}^{11} = \frac{7 {}^{11} }{4 {}^{11} }$

Since we are multiplying an exponential number to a fraction the answer is going to be

Answer: A=2, B=5, C=4

Step-by-step explanation:

$\frac{6x^{2}+13x-5}{x^{2}-16} \cdot \frac{x+4}{3x-1}\\\frac{(3x-1)(2x+5)}{(x-4)(x+4)} \cdot \frac{x+4}{3x-1}\\\frac{2x+5}{x-4}$

So A=2, B=5, and C=4.

So,

"7 more than"
7 +

"twice a number x"
2 * x or 2x

"7 more than twice a number x"
7 + 2x or 2x + 7
