y in the first equation because y is already by itself. All you have to do is move the -3x to the other side.
Answer:
The answer is 5X+16
Step-by-step explanation:
The formula for perimeter of a triangle is a+b+c.
meaning we are adding up everything.
That is
(x)+(x+11)+(3x+5).
collect like terms.
and u end up getting
5x+16
Answer:
The answer you are looking for is the part d
Complementary angles, sum = 90
So 3y - 4 + 73 = 90
3y + 69 = 90
3y = 21
y = 7
Answer
y = 7
-50 - (-221) = 171
This is because subtracting a negative number is like adding a positive version of that instead. For a more simple example:
5 - (-2) = 7 or 5 + 2 = 7
