Answer: 16a + 32b - 8c

Step-by-step explanation:

8(2a + 4b - c ) = 16a + 32b - 8c

Multiply 8 by 2a to get 16a

Multiply 8 by 4b to get 32b

Multiply 8 by -c or -1c to get -8c

Put them together to get 16a + 32b - 8c

In parallelogram ABCD, the measure of angle A=3x and the measure of angle B =x+10. What is the measure of angle D?

Alinara [238K]

Answer: 52.5

Step-by-step explanation: 2(3x+10)+2(x+10)=360 because all the sides of a rhombus equal 360 and alternate sides are equal

8x+20=360

-20=-20

8x/8=340/8

x=42.5

x+10. 42.5+10=52.5

D=52.5

1. Susan decides to take a job as a transcriptionist so that she can work part-time from

IRISSAK [1]

Answer:

a) About 46.3 hours

b) About $1036.80

Step-by-step explanation:

Break even means to make enough to cover her costs.

Given her cost is 1000, we need to find how many hours she will need to cover this up.

In 1 minute, she can type 90 words, that would pay her:

0.004 per word for 90 words = 0.004 * 90 = $0.36 per minute

Susan makes $0.36 per minute, so the amount of time (in minutes) it will take her to make $1000, is:

1000/0.36 = 2777.78 minutes

Converting that to hours, we divide by 60,

2777.78/60 = 46.3 hours

4 hours per day for 3 days = 4 * 3 = 12 hours (per week)

Let there be 4 weeks in a month, so

12 hours per week * 4 = 48 hours per month

She will work 48 hours per month.

Given 90 words per minute, in 1 hour, she can type:

60 minutes * 90 = 5400 words per hour

In 48 hours, she can type:

5400 words per hour * 48 hours = 259,200 words

That would pay her:

0.004 per word for 259,200 words = 0.004 * 259,200 = $1036.80

A linear equation exists for the following sets of ordered pairs: {(-1, 1), (0, 3), (-1/3, 7/3)}. The rule for the linear equati

kaheart [24]

Answer:

Part 1) $y=2x+3$

Part 2) The equation satisfy the set of coordinates (see the explanation)

Step-by-step explanation:

step 1

Find the linear equation

The rule for the linear equation states that y is three more than twice x.

The variable y is equal to the number 2 multiplied by x plus the number 3

$y=2x+3$

step 2

Prove that the equation satisfies the set of coordinates

substitute the value of x and the value of y in the linear equation and then compare the results

a) (-1, 1)

$1=2(-1)+3$

$1=1$ ----> is true

The equation satisfy the ordered pair

b) (0, 3)

$3=2(0)+3$

$3=3$ ----> is true

The equation satisfy the ordered pair

c) (-1/3,7/3)

$7/3=2(-1/3)+3$

$7/3=7/3$ ----> is true

The equation satisfy the ordered pair

therefore

The equation satisfy the set of coordinates
