Answer:

For $x=2$

Step-by-step explanation:

This problem reduces to solving the equation

$4(5x-8)=2(4-x)+4$

we expand both sides

$20x-32=8-2x+4$

rearrange and solve for x:

$22x=8+4+32$

$22x=44$

$\boxed{x=2}$

which is our answer.

Answer:

A.) x / 3 = 12 ----> x = 12(3) ----> x = 36

B.) 2x + 3 = 20 ----> 2x = 17 ----> x = 17/2

C.) 4/3x = 10/3 ----> x = 10/3 x 3/4 ----> x = 30/12 = 5/2

D.) -4x = -24 ----> x = -24/-4 ----> x = 6

E.) 2(x-4) = 10 ----> 2x - 8 = 10 ----> 2x = 18 ----> x = 9

F.) -0.5x + 1.1 = -2.9 ----> -0.5x = -4 ---> x = -4 / -0.5 ----> x = 8

Write, in slope intercept form, the equation of the line that passes through (8, -9) and has a slope of -5/4.

dezoksy [38]

Answer:

The equation in the slope-intercept form will be:

$y=-\frac{5}{4}x+1$

Step-by-step explanation:

Given

slope = m = -5/4

point = (8, -9)

As we know that the equation of a line in point-slope form is

$y-y_1=m\left(x-x_1\right)$

substituting the values m = -5/4 and point = (8, -9)

$y-\left(-9\right)=\frac{-5}{4}\left(x-8\right)$

$y+9=\frac{-5}{4}\left(x-8\right)$

Writing the equation in slope-intercept form

$y=mx+b$

where m is the slope, and b is the y-intercept

so the equation of the line in slope-intercept form becomes

$y+9=\frac{-5}{4}\left(x-8\right)$

subtract 9 from both sides

$y+9-9=\frac{-5}{4}\left(x-8\right)-9$

$y=-\frac{5}{4}x+1$

Therefore, the equation in the slope-intercept form will be:

$y=-\frac{5}{4}x+1$

I need help on the yes and no one

lutik1710 [3]

Hello from MrBillDoesMath!

Answer:

10a. YES

10b. YES

10c. NO

10d . YES

Discussion:

If x = 12

10a. Does (3/4) 12 = 9? Does (36/4) = 9 = 9? YES

10b. Does 3x = 36? Does 3(12) = 36 = 36? YES

10c. Does 5x = 70? Does 5(12) = 60 = 70? NO

10d. Does x/3 = 4? Does 12/3 = 4 = 4 ? YES

Thank you,

MrB

Pllsssss help Explanation plsss

aleksklad [387]

Answer:

x = 17

Step-by-step explanation:

8x - 9 + 53 = 180 (collect like terms)

8x + 44 = 180 (subtract 44 on both sides)

8x = 136 (divide by 8 on each side)

x = 17
