Your answer is -2n+13
Steps:
-2(n-9)+4, multiply -2 with (n-9)
-2n+9+4, when you multiply two negatives together you get a positive number
-2n+13, combine like terms
Answer:
x = 1/3
Step-by-step explanation:
-12x + 12 = 4 - 15x + 9
Combine like terms
-12x +12 = -15x+13
Add 15x to each side
-12x+12 +15x = -15x+15x+13
3x+12 = 13
Subtract 12 from each side
3x+12-12 = 13-12
3x = 1
Divide by 3
3x/3 = 1/3
x = 1/3
Answer:
x = 44
Step-by-step explanation:
These angles are supplementary so that means they add up to 180:
47 + 3x + 1 = 180
3x + 48 = 180
3x = 180 - 48
3x = 132
x = 44
28) ANSWER: x=5
Because 5*5=25.
29) ANSWER: x=4
3x^2=48
Divide both sides by 3.
x^2=16
x=4
Because 4*4=16.
