Answer:
33
Step-by-step explanation:
first you set up the problem, supplementary angles equal 180 degrees so the equation should look like, 4x+x+15=180. then you solve from there by combining like terms and you should get x equal to 33
Answer:
35
Step-by-step explanation:
0.25 x 140 = 35
X= -15
First, we want to combine like terms.
4x-10=20+6x
Subtract 4x from both sides
-10=20+2x
Subtract 20 from both sides
-30=2x
Divide by 2 to isolate the variable
X= -15
Answer:
A
Step-by-step explanation:
18 + 12 = 30
A: 6 (3 + 2) = 30
Simplified 6*5 = 30
Answer:
Step-by-step explanation:
4 is coefficient
x is variable
12 is constant
