First, we start with the equation that the problem told us, which is:

R + 6 = 2 * (x + 6)

Then, we distribute the two:

R + 6 = 2x + 12

Now, we put R on its own side.

R = 2x +6

So, the answer must be C, 2x + 6

Answer:

The expression for Ralph's age in 6 years is 3x +6

Present age of Ralph is 18 years.

Step-by-step explanation:

Let the present age of Sarah's is x.

Hence, present age of Ralph is 3x

In 6 years, it has been given that Ralph will be only twice as old is Sarah will be then. Thus, we must add 6 to the present age of both.

Sarah's age is x+6

Ralphs's age is 3x+6

Hence, we have

3x+6 =2(x+6)

Solving the equation for x

3x + 6 = 2x +12

x = 6

Hence, Ralph's present age is

3x

= 3×6

= 18

The expression for Ralph's age in 6 years is 3x +6

Present age of Ralph is 18 years.

NEED HELP ASAP PLEASE WITH #9 and #10!!

9) Because the total number of pencils is 180 and you will use them up in 30 days, the equation will have to equal 0 total pencils when 30 is substituted in for the time factor, or x. This already takes our choice 3 because it doesn’t meet this criteria.
The answer to how many pencils in 20 days could be answered by plugging in 20 for x. Choice 4 cannot work because it results in a negative number of pencils. Choices 1 and 2 use the same equation, so by plugging in 20 it is clear choice 2 is the correct answer.

10) A line parallel to the go en equation would have the same slope, -3, which means choices 1 and 4 are out. Plug in (-2,5) into both choices 2 and 3. Plugging -2 into x in choice 2 gives -5, and in choice 3 gives 5 for the y value. Therefore choice 3 is correct.
