Answer:
54 degrees
Step-by-step explanation:
Complementary angles add to 90 degrees
3:2
Multiply each by x
3x:2x
Add the angles together and set equal to 90
3x+2x = 90
Combine like terms
5x= 90
Divide each side by 5
5x/5 = 90/x
x =18
The angles are 3x = 3(18) =54
and 2x = 2(18) = 36
Answer:
2/8
Step-by-step explanation:
A < 16
The answer is C
You treat it like an equation, since you don't divide by negative numbers the sign stays the same<span />
So this easiest way to solve is to use the elimination method. Basically you just add the equations together. This is what you do.
-5x + y = -11
x - y = 7
Add the equations.(This operation gets rid of the y-value)
-4x = -4
Divide.
x = 1
Now plug in 1 into an equation of your choice and find the value of y.
1 - y = 7
Subtract 1 from both sides.
-y = 6
Divide by -1 because you can't have a -y.
y = -6
So the solution is (1, -6).
