The answer would be D. an interval isnt a certain number but it is a time something happens over and over again
Answer:
-1/2
Step-by-step explanation:
2(x-4)=6x-6
2x-8=6x-6
2x-6x-8=-6
-4x-8=-6
-4x=-6+8
-4x=2
x=2/-4
simplify
x=-1/2
Answer:
D) -20/-5 because a negative divided by a negative is a positive.
Step-by-step explanation:
Answer: 57.1
Step-by-step explanation: To be complementary the angles have to add up to make a sum of 90.

The angles are 32.9 and 57.1.
Answer:
x=-2
Step-by-step explanation:
You can substitute the first equation into the second:
-3x+3=5x+19
Add 3x on both sides:
3=8x+19
Subtract 19 on both sides:
-16=8x
Divide 8 on both sides:
x=-2
