-85 - 8x = 2x + 115
-85 + 85 - 8x = 2x + 115 + 85
-8x = 2x + 200
-8x - 2x = 2x - 2x + 200
-10x = 200
-10x/-10 = 200/-10
X = -20

Answer: x= -20

Step-by-step explanation:

Add 85 85 to both sides.

-8x=2x+115+85−8x=2x+115+85

Simplify 2x+115+852x+115+85 to 2x+2002x+200.

-8x=2x+200−8x=2x+200

Subtract 2x2x from both sides.

-8x-2x=200−8x−2x=200

Simplify -8x-2x−8x−2x to -10x−10x.

-10x=200−10x=200

Divide both sides by -10−10.

x=-\frac{200}{10}x=−

200

Simplify \frac{200}{10}

200

to 20 20.

x= - 20

List 3 values that would make this inequality true 4n <_ 12

timama [110]

<span>Divide both sides by 4 to get

$4n \le 12$

$\frac{4n}{4} \le \frac{12}{4}$

$n \le 3$

So we can pick n to be 3 or it can be less than 3

Three values we can pick are: n = 0, n = 1, n = 2

Or we could pick: n = 1, n = 2, n = 3

Find the equation of the line in gradient form that passes through the points (3,0) and (-2,4)

Aleksandr-060686 [28]

Answer:

y = (-4/5)x + 12/5

Step-by-step explanation:

Slope = (4-0)/(-2-3) = 4/-5 = -4/5

y = (-4/5)x + c

When x = 3, y = 0

0 = (-4/5)(3) + c

c = 12/5

y = (-4/5)x + 12/5

5y = -x + 12

5y + x = 12

the ratio of men and women in a certain factory is 3 to 4. there are 198 men. How many workers are there?

LUCKY_DIMON [66]

3 men

4 women

7 total

3 men/ 7 total = 198 men/ x total

using cross products

3*x = 7 * 198

divide each side by 3

x = 7*198/3

x = 462

There are 462 workers

If you mean 3 men and 1 women for a total of 4 workers when you state a ratio of men and women in a certain factory is 3 to 4.

3/4 =198/x

Using cross products

3x = 4* 198

Divide each side by 3

3x/3 = 4*198/3

x =264

264 workers

It all depends on how you define ratio of men and women in a certain factory is 3 to 4. This is incorrect phrasing and I took it to be men to women. You cannot have a ratio of men and women.

15d^3+30d^2+30d/3d3 what is the answer if you divide the following

lawyer [7]

When you separate them
$\frac{15d^{3} }{ {3d}^{3} } + \frac{30d^{2} }{ {3d}^{3} } + \frac{30d }{ {3d}^{3} } = x$
Solve them separately:
$5 + \frac{10}{d} + \frac{10}{ {d}^{2} } = x$
Remove the denominators:
$5 + 10 {d}^{ - 1} + 10 {d}^{ - 2} = x$
Find GCF (Greatest Common Factor):
$5(1 + 2 {d}^{ - 1} + 2 {d}^{ - 2} ) = x$
