Answer:
If b is 3, x=-1
Step-by-step explanation:
-2(3x-5)=16
use distributive property
-6x+10=16
take 10 away from both sides
-6x=6
divide both sides by -6
x=-1
I think it is a)57 because 84-27=57 or b because it is less than 90
Answer:
Y=109 X=31
Step-by-step explanation:
Alright, so the angles that you have to find the values for make up 180 degrees. Since you have 71 degrees on the bottom, and according to a certain theorem I forgot about, that means that the angles you're solving for equal 109 degrees.
X= 31 because 4 x 31 = 124 and then 124 - 15 equals 109
Answer:
In this equation, the value of x is 9.
Step-by-step explanation:
-4(6x + 3) = -12(x + 10)
Distribute -4 to (6x + 3) and distribute -12 to (x + 10).
-24x - 12 = -12x - 120
Add 12x on both sides of the equation.
-12x - 12 = -120
Add 12 on both sides of the equation.
-12x = -108
Divide -12 on both sides of the equation.
x = 9
The value of x in this equation is 9.
