Answer:
10°
Step-by-step explanation:
According remote interior angles, 4k + 5 + 6k + 10 = 115.
10k + 15 = 115
10k = 100
k = 10
Hope this helps :)
Have a nice day!
Total angles on a straight line
(9x + 8) + 37 = 180
9x + 45 = 180
9x = 180 - 45
9x = 135
Divide through by 9
x = 15
Answer:
4.727
Step-by-step explanation:
An easy way to think of something being divided by a fraction is by turning the fraction into a decimal. In this case, it's 5 1/2, which is the same as 5.5. So, you can just calculate 26 / 5.5, by hand, or on a calculator, and the answer is 4.727.

Answer:
2
Step-by-step explanation:
x2+3x=6
Step 1: Subtract 6 from both sides.
x2+3x−6=6−6
x2+3x−6=0
For this equation: a=1, b=3, c=-6
1x2+3x+−6=0
Step 2: Use quadratic formula with a=1, b=3, c=-6.
