Answer:

x=11

Step-by-step explanation:

First, we know that "supplementary" angles add up to 180 degrees. With this in mind, we can plug the values from your model into an equation:

(7x+33)+70=180

To solve this, first drop the parentheses because nothing is being distributed to the values inside them:

7x+33+70=180

Now we combine like terms, adding the 33 and the 70.

7x+103=180

Let's get rid of the 103 by subtracting it from both sides:

7x=77

Now we divide both sides by 7:

x=11

HTH :)

10x + 4y = 24 6x +12y = 48 What is the value of y? * A. 7 B. 7/2 C. 1 D. -7/2

ziro4ka [17]

Answer:

Step-by-step explanation:

1) lets use elimination to solve this:

multiply 10x+4y=24 with 3 in order to get "4y" into "12y"

3(10x+4y=24)

30x+12y=72

now subtract both equations to eliminate 'y"

30x+12y=72

6x+12y=48

---------------------

24x=24

x=1

now substitute 1 in the above equation:

6(1)+12y=48

6+12y=48

12y=42

y=7/2

The groundhog population of Punxsutawny, Pennsylvania is closely monitored each year. Two years ago the population decreased by

kap26 [50]

Answer:

There was a increase of 1.7% over these three years

Step-by-step explanation:

Multipliers:

For a decrease of a%, we multiply by: $\frac{100-a}{100}$

For a increase of a%, we multiply by: $\frac{100+a}{100}$

What was the percentage increase/decrease of groundhogs over these three years?

Decrease of 12%(multiplication by 0.88).

Increase of 6%(multiplication by 1.06).

Increase of 9%(multiplication by 1.09).

After these three years:

0.88*1.06*1.09 = 1.017

1.017 - 1 = 0.017

0.017*100% = 1.7%

There was a increase of 1.7% over these three years

guajiro [1.7K]

Answer:

The answer is (1,0) and (5,2)

Step-by-step explanation:

Since they are asking for parallel lines that means the slopes of the lines has to be the same line AB slope is 1/2 if you find the slope of (1,0) and (5,2) it will be the same as 1/2
