Answer for 5x+3x=420

Step 1: Simplify both sides of the equation.

5x+3x=420

(5x+3x)=420(Combine Like Terms)

8x=420

Step 2: Divide both sides by 8.

$\frac{8x}{8}$ = $\frac{420}{8}$

x = $\frac{105}{2}$

Answer for 12x+9=1080

Step 1: Subtract 9 from both sides.

12x+9−9=1080−9

12x=1071

Step 2: Divide both sides by 12.

$\frac{12x}{12}$ = $\frac{1071}{12}$

x = $\frac{357}{4}$

Anna [14]

Answer:

6+33=39 now we subtract from 100

100-39=61

He won 61 percent of the games

now we multiply 1200*0.61=732

so he won 732 of the 1200 games

Question

Goryan [66]

Given:

(2, 4) and (3, 3) are on the line.

To find:

The equation of line in point slope form.

Solution:

If a line passes through a point $(x_1,y_1)$ with slope m, then the point slope form of the line is

$y-y_1=m(x-x_1)$

(2, 4) and (3, 3) are on the line. So, slope of the line is

$m=\dfrac{y_2-y_1}{x_2-x_1}$

$m=\dfrac{3-4}{3-2}$

$m=\dfrac{-1}{1}$

$m=-1$

The slope of a line is -1 and it passes through (2,4). So, an equation in point slope form is

$y-4=-1(x-2)$

Therefore, an equation of the line in point slope form is $y-4=-1(x-2)$ .
