Answer:

y = 37, x = 18.5

Step-by-step explanation:

O = 16 because of the vertical angles rule. The degrees on a straight line is 180 degrees. That means that because AB is a straight line, 2y + O + 90 = 180. We also know that CD are straight, so O + 4x +90 = 180.

Now we solve for x and y:

2y + O + 90 = 180

2y + 106= 180

2y = 74

y = 37

O + 4x +90 = 180

16 + 4x +90 = 190

4x + 106 = 180

4x = 74

x = 18.5

I hope this helps, I'm not entirely sure if it's right, you may want to try to check!

Answer:

y=37

Step-by-step explanation:

90+2y+16=180

106+2y=180

2y=74

y=37

16+4x+90=180

106+4x=180

4x=74

x=18.5

What's 17= z- (-9) days
Arte-miy333 [17]
Z - (-9) is the same as z + 9. Subtracting a negative is the same as adding.

Therefore 
17 = z - (-9)
is the same as
17 = z + 9

To get 'z' all by itself, we need to subtract 9 from both sides. We subtract 9 from both sides to undo the "plus 9" occurring to the 'z' on the right side.

17 = z + 9
17-9 = z + 9=9 ... subtracting 9 from both sides
8 = z
z = 8

So the answer is z = 8

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

Check:

17 = z - (-9)
17 = 8 - (-9) ... replace z with 8
17 = 8 + 9
17 = 17
