Answer:
x = -10
Step-by-step explanation:
2(x + 3) = x + -4
Reorder the terms:
2(3 + x) = x + -4
(3 * 2 + x * 2) = x + -4
(6 + 2x) = x + -4
Reorder the terms:
6 + 2x = -4 + x
Solving
6 + 2x = -4 + x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-1x' to each side of the equation.
6 + 2x + -1x = -4 + x + -1x
Combine like terms: 2x + -1x = 1x
6 + 1x = -4 + x + -1x
Combine like terms: x + -1x = 0
6 + 1x = -4 + 0
6 + 1x = -4
Add '-6' to each side of the equation.
6 + -6 + 1x = -4 + -6
Combine like terms: 6 + -6 = 0
0 + 1x = -4 + -6
1x = -4 + -6
Combine like terms: -4 + -6 = -10
1x = -10
Divide each side by '1'.
x = -10
Answer:
ABC = 27
DBC = 56
Step-by-step explanation:
ABC + CBD = ABD
x+10 + 4x-12 = 83
Combine like terms
5x -2 = 83
Add 2 to each side
5x-2+2 = 83+2
5x = 85
Divide each side by 5
5x/5 = 85/5
x =17
ABC = x+10 = 17+10 = 27
DBC = 4x-12 = 4*17 -12 = 68-12 = 56
Answer: $418
Step-by-step explanation:
This is because you find 5% of $440 which is 22. Then you subtract 22 from 440 which is 418, thus the answer
so the solution is not really a single number but a range, depending on how q is defined. I am assuming q is defined in domain of Real numbers, and then the solution to the inequality will be "all real numbers larger or equal to 4.7"
