Help???<br> Its a two step inequality problem. I dunno what X equals too.
Verizon [17]

Answer:

x \geq -1

Step-by-step explanation:

-4x + 2 \geq -6x

Add 6x to both sides:

-4x + 2 + 6x \geq -6x + 6x

2x + 2 \geq 0

Subtract 2 from both sides:

2x + 2 - 2 \geq 0 - 2

2x \geq -2

Divide both side by 2:

\frac{2x}{2} \geq \frac{-2}{2}

x \geq -1

Jasmine buys the magic carpet on sale for $374. She saved $66 off the regular price. What percent was the price discounted?
Furkat [3]

Answer:

15%

Step-by-step explanation:

Let c represent the regular price of the carpet.

Then:  

sale price = regular price less discount

    $374    =           c     -     $66

Adding $66 to both sides isolates (solves for) c:

$374 + $66 = c  =   $440.  This is the regular price.

 $66

---------- = 0.15                      This is the fraction of the regular price by

$440                                   which the regular price is reduced.

Then the percentage of this discount was   0.15(100%) = 15%
