7x - 2 < 10

Add two to each side.

7x - 2 (+2) < 10 (+2)

Your new equation is: 7x < 12

Divide each side by 7.

7x/7 < 12/7

x < 12/7 or 1 and 5/7

Which scenario is modeled by the equation (x)(0.6) = $86.46?

belka [17]

Answer: A picnic table is on sale for 60 percent off. The original price of the picnic table is x, $144.10.

Step-by-step explanation:

Given equation: $(x)(0.6)=\$86.46$

To find x, divide 0.6 on both sides, we get

$x=\frac{\$86.46}{0.6}\\\Rightarrow\ x=\frac{\$864.6}{6}\\\Rightarrow\ x=\$144.10$

Also $0.6=0.6\times100=60\%$

Thus, $60\%\ of\ \$144.10=\$86.46$

So the best scenario modeled by the above equation is

"A picnic table is on sale for 60 percent off. The original price of the picnic table is x, $144.10."
