Answer:

104

Step-by-step explanation:

The angle is supplementary, so the total angle measure (of 79 and x) is 180. Just subtract the value we have (76) from the total value (180), and you get x.

How many solutions are there to 3x-10(x+2) =13-7x

Vaselesa [24]

This is the following way to solve this problem:

3x-10(x+2)=13-7x

3x-10x-20=13-7x (multiply 10 times what's in the parentheses)

-7x-20=13-7x ( subtract 3x from -10x)

-7x-20-13=-7x ( since the 13 is positive, when we move it to the other

side, we change it's sign, so now we subtract 13 from 20

-7x-7=-7x

-7=-7x+7x ( we do the same thing we did above, now with the -7x)

-7=x

x=-7

Answer: x = -7

X-23 / x^2 -x- 20 - 2/5-x

alexira [117]

By simplifying $x - \frac{{23}}{{{x^2}}} - x - 20 - \frac{2}{5} - x$ . This will result in a simplified version of $- \frac{{5{x^3} + 102{x^2} + 115}}{{5{x^2}}}$ .

The Simplifying Algorithm is a wonderful way to simplify complex mathematics problems. It can be used to solve equations, convert fractions to decimals, and perform many other math operations. In this problem, the Simplifying Algorithm will help you reduce $x - \frac{{23}}{{{x^2}}} - x - 20 - \frac{2}{5} - x$

Since two opposites add up to 0, remove them from the expression.

$- \frac{{23}}{{{x^2}}} - \frac{{102}}{5} - x$

Write all numerators above the least common denominator 5x2

$- \frac{{115 + 102{x^2} + 5{x^3}}}{{5{x^2}}}$

Use the commutative property to reorder the terms so that constants on the left

$\frac{{ - 5{x^3} - 115 - 102{x^2}}}{{5{x^2}}}$

Rearrange the terms

$\frac{{ - 5{x^3} - 102{x^2} - 115}}{{5{x^2}}}$

By reording the terms

$- \frac{{5{x^3} + 102{x^2} + 115}}{{5{x^2}}}$

Hence, by simplifying this equation, divide both numerator and denominator. This will result in a simplified version of $- \frac{{5{x^3} + 102{x^2} + 115}}{{5{x^2}}}$ .
