Which of the value of x satisfies the equation below -2x-7=12
Masteriza [31]
Answer is A.
You start by adding the 7 to the opposite side. Giving you 19. You divide both sides by -2 which gives you x on one side and -9.5 on the other.

-2x-7=12
-2x=12(+7)
-2x=19
x=19/-2
x=-9.5

Simplify 1/x-10 divided by 9x/x^2-9x-10
Virty [35]
In fractional form, I think this is written as

\frac{1}{x-10} / \frac{9x}{ x^{2} -9x-10}

When dividing, the first term is the dividend, the second term is the divisor and the answer is the quotient. When you divide fractions, you multiply the dividend with the reciprocal of the divisor. In this case

\frac{1}{x-10} * \frac{x^{2} -9x-10}{9x }

The answer is 

\frac{ x^{2} -9x-10}{9 x^{2} -90x}

Furthermore, we can simplify the terms through factoring, The numerator could be factored into (x+1)(x-10). The denominator could be factored to 9x(x-10). Since the term (x-10) is common, you can cancel them to get to the final answer which is

(x+1)/9x

12m+14g=x where x is his total earnings for the week
12m+12g+2g=x, so x-2g=12(m+g) and x-2g≤480. Or x≤480+2g. His earnings cannot exceed 480+2g.
