To find the incompleted portion of the test, convert the decimal to a percentage by moving the decimal two places to the right. .7 as a percentage is 70%. subtract 70% from 100%, giving you 30%. Juan has not completed 30% of his test, or 5 questions.

Answer:

0=0

Step-by-step explanation:

Add zero

0+2=2

2=2

Subtract 2 from both sides of the equation

2=2

2−2=2−2

Simplify

Combine like terms

2−2=2−2

0=2-2s

or

0=2s-2

0=0

19. Two angles are supplementary. The measure of one angle is four times the measure of the other angle. Find the measure of eac

Marysya12 [62]

36 and 144

Explanation

Two Angles are Supplementary when they add up to 180 degrees

Step 1

Let

x= angle 1

y= angle2

The measure of one angle is four times the measure of the other angle,then

$\begin{gathered} \text{angle}1=4\cdot\text{angle}2\text{ } \\ x=4y\text{ Equation(1)} \end{gathered}$

x and y are supplementary angles , then

$x+y=180\text{ Equation (2)}$

Step 2

use Equation (1) and (2) to find x and y

$\begin{gathered} x=4y \\ x+y=180 \end{gathered}$

replace Equation (1) in Equation (2)

$\begin{gathered} 4y+y=180 \\ 5y=180 \\ y=\frac{180}{5} \\ y=36 \end{gathered}$

replace the value of y= 36 in equation (1) to find x

$\begin{gathered} x=4y \\ x=4\cdot36 \\ x=144 \end{gathered}$

Hence, the answer is 36 and 144

Which expression is equivalent to 1/4 (8-6x+12)

Dovator [93]

So:

Let us simply the parenthesis first.

So we have $\sf{(8-6x+12)}$

We can rearrange the terms and get:

$\sf{(8+12-6x)}$

Which is equal to

$\sf{(20-6x)}$

So now we have to complete it by multiplying it all by 1/4 which is basically dividing it by 4.

So:

$\sf{\frac{20-6x}{4}}$

Simplifying that, we get:

$\sf{5-\frac{6}{4}x}$

And reducing that farther we finally get:

$\sf{5-\frac{3}{2}x}$

Which is your final answer :)
