Answer:

x = 16, y = 140

Step-by-step explanation:

(8x + 12)° and (3x - 8) are adjacent angles and are supplementary, sum to 180°

8x + 12 + 3x - 8 = 180

11x + 4 = 180 ( subtract 4 from both sides )

11x = 176 ( divide both sides by 11 )

x = 16

Then

8x + 12 = 8(16) + 12 = 128 + 12 = 140

(8x + 12) and y are alternate angles and are congruent , so

y = 140

Answer:

x+y=12

Step-by-step explanation:

First, substitute 3y for the spots with x:

2(3y) + 2y = 24

6y+ 2y = 24

8y= 24

y= 3

Then sub in 3 in the y place:

x= 3(3)

x= 9

Then plug in the x and y values in the equation:

9 + 3 =12

Good Luck!!!

Find the length of each line segment or object to the nearest half or fours or eighth inch

Aliun [14]

Answer:

a. $1\frac{1}{8} in.$

Step-by-step explanation:

hey there,

< There are 8 marks between 1 in. and 2 in. and here we can see that the distance of the line goes only up to the first mark.

Imagine this like a pizza that's divided into 8, but you only took 1 slice. That means you took only $\frac{1}{8}$ of the pizza. It is the same here on the ruler.

It's not only 1/8 though because we also have to add in the first inch. After that inch, we also have 1/8 of an inch. So $1\frac{1}{8}$ in. would be your final answer. >

Hope this helped! Feel free to ask anything else.
