Supplementary angles add up to 180°
x = greater supplementary angle
x - 118 = lesser angle
x + (x - 118) = 180
2x - 118 = 180
2x = 298
x = 149
x - 118
149 - 118 = 31
the angles are 31° and 149°
Answer:
11
Step-by-step explanation:
Unknown number = x
If twice the difference of x and 8 is 6:
2(x-8) = 6
2x-16 = 6
2x = 6 + 16
2x = 22
x = 22/2
x = 11

Answer:
No.
Step-by-step explanation:
Sam is incorrect because if you look at the original problem, you'll see that he has missed the negative sign!
90 / 9 does equal 10, but 90 / -9 equals -10.
The only way to get a positive answer is if both the divisor and dividend are positive or if they are both negative.
Thus, the correct answer should be -10.
