Answer:
It's just addition and subtraction.
Step-by-step explanation:
1. $65,000
2. 66,000
3. 114,000
Always because the sum of x and y is 180 degrees. If x and y are right angles, then x and y are supplementary angles. Never because the sum of x and y has to be 90 degrees. If x and y are complementary angles, then y is a right angle.
(7 / 2 ) / 100
3.5 / 100
0.035
So your answer is 0.035
2x=16-2y
x=8-y
6(8-y)+4y=38
48-6y+4y=38
48-2y=38
-2y=-10
y=5
8-5=x
x=3 <-Answer
To multiply fraction do top x top and bottom x bottom
