Answer:
The answer is C
Step-by-step explanation:
We must multiply and divide before adding and subtracting here. Working from left to right, we get:
8 + 15 - 5 = ?
8 + 10 = ?
18 (answer)
A straight line is 180 degrees:
25x + 8 + 9x + 2 = 180
Combine like terms:
34x + 10 = 180
Subtract 10 from both sides:
34x = 170
Divide both sides by 34:
X = 5
Now solve the smaller angle:
9x + 2 = 9(5) + 2 = 45 + 2 = 47
They angle with the y is a vertical angle to 47 so needs to also equal 47:
7y + 5 = 47
Subtract 5 from both sides:
7y = 42
Divide both sides by 7:
Y = 6
Answer: x = 5, y = 6
Answer:
-6.1 - (-3.13) = -2.97
