Answer:
x = -9
Step-by-step explanation:
- Add 12 to each side, so it now looks like this: -3x = 27
- Divide each side by -3x, so it now looks like this: x = -9
I hope this helps!
Answer:
B
Step-by-step explanation:
-5x = y - 5 (1)
-2y = -x - 21 (2)
Change x to the left hand side of equation (2)
x = 2y - 21 (3)
Multiply (1) by 2 times:
-10x = 2y - 10 (4)
Use (4) - (3)
-10x = 2y - 10
- x = 2y - 21
-11x = -10 + 21
-11 x = 11
x = -1
Apply x = -1 in (1)
-5*(-1) = y - 5
5 = y-5
y = 5+5
y = 10
So x = -1
y = 10

Answer:80%
Step-by-step explanation: If you divide 16 and 20, you get 0.8 and multiply that by 100, you get 80%.
<span>12.5% of 64=8 Would be the answer to this.</span>
the answer is 130 degrees, the 2 interior bottom angles are = to one another so 65 and 65, adding them up makes it 130, then 180 - 130 = 50, meaning the top interior angle is 50 degrees, then 180 - 50 is 130.
