Answer:

2; 10

Step-by-step explanation:

12/2 = 6

(x+6)^{2} = x^{2} +12x + 36

   x^{2} +12x + 20

-   x^{2}<u> +12x + 36</u>

    0 + 0  - 16

(x+6)^{2} - 16 = 0

(x+6)^{2} = 16

x + 6 = \sqrt{16}

x = -4 + 6 = <u>2</u>

x = 4 + 6 = <u>10</u>

Susan works as a tutor for $10 and hour, and as a waitress for $11 an hour. This month, she worked a combined total of 90 hours
uysha [10]

Answer:

\$(990-t)

Step-by-step explanation:

The correct question is

Susan works as a tutor for $10 and hour, and as a waitress for $11 an hour. This month, she worked a combined total of 90 hours at her two jobs. Let t be the number of hours Susan worked as a tutor this month. Write an expression for the combined total dollar amount she earned this month

Let

t -----> the number of hours that Susan work as a tutor

y ----> the number of hours that Susan work as a waitress

z ---> the combined total dollar amount she earned this month

we know that

t+y=90

y=90-t-----> equation A

we know that

The combined total dollar amount she earned this month is equal to the number of hours that Susan work as a tutor multiplied by $10 plus the number of hours that Susan work as a waitress multiplied by $11

z=10t+11y ----> equation B

substitute equation A in equation B

z=10t+11(90-t)

z=10t+990-11t

z=990-t

therefore

The expression for the combined total dollar amount is $(990-t)

An angle measure 20 more than the measure of its supplementary angle.What is the measure of each angle?
SOVA2 [1]

Based on the definition of supplementary angles, the measure of both angles are: 80° and 100°.

<h3>What are Supplementary Angles?</h3>

The sum of angles that are supplementary to each other equals 180 degrees.

Let the measure of the supplementary angle be x.

The other angle will be: x + 20.

(x + 20) + x = 180

x + 20 + x = 180

2x + 20 = 180

2x = 180 - 20

2x = 160

x = 160/2

x = 80°

The other angle will be x + 20 = 80 + 20 = 100°.

The measure of the angles are: 80° and 100°.
