<h2>Hello There today we will solve your problem</h2>

Solve for x please :-

3(9+x)-31=20

_____________________

<h2>Definitions</h2>

To use the distributive property, we need to understand the formula to use it. This formula will ensure that you can easily solve any equation.

The distributive property is A(B + C) = AB + AC, where AB is the product of the values A and B and AC is the product of the values A and C.

First, let's notice that we are distributing a 2 into the parentheses, so we will mark this as our A value.

Then, our two values inside the parentheses are B and C respectfully.

Apply Distributive property

3(9)+3(x)-31=20\\27+3x-31=20\\3x-31=-7\\3x=24\\x=8

Write an equation, in point-slope form, for the line that goes through points (4,4) and (-4,-1).
Soloha48 [4]

Answer:

C.) Y= 5/8x + 1 1/2

Step-by-step explanation:

To write the equation of a line, calculate the slope between points (4,4) and (-4,-1). After, substitute the slope and a point into the point slope form.

m = \frac{y_2-y_1}{x_2-x_1} = \frac{4--1}{4--4}= \frac{5}{8}

Substitute m = 5/8 and the point (4,4) into the point slope form.

y - y_1 = m(x-x_1)\\y -4 = \frac{5}{8}(x-4)\\y-4 = \frac{5}{8}x - \frac{20}{8} \\\y = \frac{5}{8}x - 2{1}{2} + 4 \\ y = \frac{5}{8}x + 1\frac{1}{2}

the measure of ∠D is 5 times the measure of ∠E the two angles are supplemanty find the measure of each angle
hammer [34]
Because the angles are supplementary, they add to 180 degrees.

I solved this by dividing \frac{180}{6} which gives me 30 degrees.

multiply 30 by 5 gives you 150.

and 30 + 150 = 180
