The correct answer is C. x = 9.

To find this first distribute the numbers on the outside of the parenthesis.

-4(6x + 3) = -12(x + 10)

-24x - 12 = -12x - 120

Now move all the constant values to the right and all of the x values to the left.

-24x - 12 = -12x - 120

-24x = -12x - 108

-12x = -108

Now divide by -12 to solve

x = 9

Kaylis [27]

The average number of miles he will ride each day to meet his goal is 6.6 miles

<h3>How to find the average number of miles she will ride?</h3>

He wants to ride his bicycle 30.4 miles this week.

He has already ridden 4 miles.

He rides 4 more days.

Therefore, the average number of miles he would have to ride each day to meet his goal can be calculated as follows:

let

x = number of miles driven

Hence, the equation can be represented as follows;

4x + 4 = 30.4

Therefore,

4x + 4 = 30.4

4x + 4 - 4 = 30.4 - 4

4x = 26.4

x = 26.4 / 4

x = 6.6

Therefore, the average number of miles he will ride each day to meet his goal is 6.6 miles
