Answer:
The answer is D
Step-by-step explanation:
9(x + -3) + 28 = 4x + -3
Reorder the terms:
9(-3 + x) + 28 = 4x + -3
(-3 * 9 + x * 9) + 28 = 4x + -3
(-27 + 9x) + 28 = 4x + -3
Reorder the terms:
-27 + 28 + 9x = 4x + -3
Combine like terms: -27 + 28 = 1
1 + 9x = 4x + -3
Reorder the terms:
1 + 9x = -3 + 4x
Solving
1 + 9x = -3 + 4x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-4x' to each side of the equation.
1 + 9x + -4x = -3 + 4x + -4x
Combine like terms: 9x + -4x = 5x
1 + 5x = -3 + 4x + -4x
Combine like terms: 4x + -4x = 0
1 + 5x = -3 + 0
1 + 5x = -3
Add '-1' to each side of the equation.
1 + -1 + 5x = -3 + -1
Combine like terms: 1 + -1 = 0
0 + 5x = -3 + -1
5x = -3 + -1
Combine like terms: -3 + -1 = -4
5x = -4
Divide each side by '5'.
x = -0.8
Simplifying
x = -0.8
B/4 x 4 = 7.25 x 4. b = 29. hope this helps :)
Answer:
I got<u> -8, </u>hope dis helps!
Since the other angle that right next to it, the same angle you equal both angles together.
4x = 68.
We want to get x by its self. There is a 4 with the x and they're multiplying. to get rid of 4 we need to the opposite of multiplying which is division on both sides of the equation.
4x = 68
/4 /4
4 divided by 4 is 1 and 68 divided by 4 is 17
x = 17 is the answer.
If you plug in x = 17 into 4x, it will be 68
The distance around the bulletin board would be 20 feet, because you multiply 6ft 2x and 4ft 2x.
