Answer:
A. 93
Step-by-step explanation:
Each angle is 90 degrees.
18x = 90
x=5
x + y = 90
5 + y = 90
y = 85
30z = 90
z = 3
5 + 85 + 3 = 93
Answer:
(x, y) → (x - 8, y + 4)
Step-by-step explanation:
Answer:
<u>Yes</u>
- (2 · x) + (2 · 7) = 36
- x + 7 = 18
- 2x + 14 = 36
<u>No</u>
- 2x + 7 = 36
- 2(x + 7) = 72
- x + 14 = 36
Step-by-step explanation:
It is appropriate to eliminate parentheses as a first step. This can be done using the distributive property, resulting in either of ...
- 2x +2·7 = 36
- 2x +14 = 36 . . . . . 2·7 evaluated mentally
or by dividing the equation by the factor outside parentheses, resulting in ...
___
Any of the equations other than these represent violations of the equal sign. Something has been done to one side of the equation without the same thing being done to the other side.
Answer:
y = 65 degrees
Step-by-step explanation:
You can use a vertical angle to figure this out. Since 65 is a vertical angle to y, it equals the same amount. I have attached an image of an example of vertical angles. They are on the opposite side of the line.
<u />a=2
2a=2*2=4 (replace a with 2)
The answer is 4.
