It would be doubled i think actually no just do the same equation with 4. i need to see the question first
Answer:
4
Step-by-step explanation:
You call the number x. Then you do (x-7) * 3=-9.
3x-21=-9
3x=12
x=4
Answer: 192.6
Step-by-step explanation:
I took the test
Step-by-step explanation:
Let x° be the original angle. Then the supplement angle is (180 - x)° and (180 - x) = 3x + 24.
180 - x = 3x + 24
4x = 156
x = 39
Hence the original angle is 39° and the supplementary angle is 141°.
