Escape what is on sale for 60% off the regular $80 price what is the sales price
mylen [45]

Answer:

$32 is the sales price.

Step-by-step explanation:

First, change the percentage to a decimal.

60% = 60/100 = 0.6

Next, multiply 0.6 with the regular price ($80)

80 x 0.6 = 48

$48 is the discount. Subtract from the original price

80 - 48 = 32

$32 is the sales price.

Solve: 5 | x + 2 | + 2 > 7 The answer has the form: ( − ∞ , A ) ∪ ( B , ∞ ) ( A , B ) State your solution using interval nota
aliina [53]

Given:

5|x-3|+3>7

Aim:

We need to find the value of x.

Explanation:

Subtract 3 from both sides of the equation.

5|x-3|+3-3>7-3

5|x-3|>4

Divide both sides of the equation by 5.

\frac{5}{5}|x-3|>\frac{4}{5}

|x-3|>\frac{4}{5}

Square both sides.

(x-3)^2>(\frac{4}{5})^2

(x-3)^2>\frac{16}{25}

x^2-6x+9>\frac{16}{25}

multiply

x^2-6x+9>\frac{16}{25}
