Answer: x < 7

Step-by-step explanation: Just like any of your two-step equations, in this inequality, start by isolating the x term which in this case is -8x by subtracting 40 from both sides.

That leaves you with -8x > -56.

To get <em>x</em> by itself, divide both sides by -8 but watch out.

If you divide both sides of an inequality by a negative,

you must switch the direction of the inequality sign.

So we have x < 7.

5-x=12 help plss now
Zielflug [23.3K]

Answer:

x = -7

Step-by-step explanation:

5-x=12

To solve for x, you must first make the equation equal to x (to make x alone on one side).

5 - x = 12

-5         -5

-x = 7

-x(-1)=7(-1)

x = -7

Can someone please calculate the length ?
masya89 [10]
<h3>Answer:  11/20</h3>

=====================================================

Work Shown:

x = unknown horizontal length

1/5 = 0.2

Perimeter = 2*(width + length)

P = 2*(0.2 + x)

P = 0.4 + 2x

Set this equal to the given perimeter of 1 & 1/2 = 1.5 and solve for x

0.4 + 2x = 1.5

2x = 1.5-0.4

2x = 1.1

x = (1.1)/2

x = 0.55

x = 55/100

x = (5*11)/(5*20)

x = 11/20
