15 POINT 1 QUESTION<br> ITS ALL UP TO YOU!!!!

Anni [7]

First, we can simplify the left side. (6+8x)/2 is equal to 3 + 4x. We can put the equation together at this point.

3 + 4x = 5x

we can subtract 4x from both sides to get our final answer,

3 = x, or x = 3. :)

Find the percent of increase to the nearest whole from 12 to 20

ankoles [38]

Answer:

The answer is

Step-by-step explanation:

To find the percentage increase we use the formula

<h3> $Percentage \: change = \frac{change}{original \: \: quantity} \times 100\%$ </h3>

From the question

The original value = 12

To find the change we subtract the smaller value from the larger one

That's

Change = 20 - 12 = 8

So the percentage increase is

<h3> $\frac{8}{12} \times 100 \%\\ = \frac{2}{3} \times 100\% \\ = 66.67\%$ </h3>

We have the final answer as

$67\%$ to the nearest whole number

Hope this helps you

If y varies directly as x, and y is 18 when x is 5, which expression can be used to find the value of y when x is 11?

Papessa [141]

5/11 = 18/y
5 y = 18 · 11
5 y = 198
y = 198 : 5
y = 39.6
