-2(3x-1)<8 on a number line
Veronika [31]

Answer:

Checkout the image below the explanation.

Step-by-step explanation:

1. First, let's solve the inequality.

Step 1: Simplify both sides of the inequality.

  • -6x + 2 < 8

Step 2: Subtract 2 from both sides.

  • -6x + 2 - 2 < 8 - 2
  • -6x < 6

Step 3: Divide both sides by -6 and flip the sign.

  • \frac{-6x}{-6}  < \frac{6}{-6}
  • x > -1

2. Now that we solved the inequality and got x > -1, that means that all values of x are more than -1. It can be represented on the number-line as this:

A table is on sale for 464 , which is 36% less than the regular price.
viva [34]
The original price was 725.
Explanation:
"36% less than" means taking 36% away from 100%. 100-36 is 64, so 64% remains when 36% is taken away. So, 64% of the original table's price is 464.
So, if the original price was x, 464=0.64x
Solve this by dividing both sides by 0,64:
725=x
So, the original price was 725.
