The multiplication property of equality could be used to solve which of the following equations?

Evgesh-ka [11]

Multiplication property of equality can be used to solve: $\frac{b}{-2} = 18$

Step-by-step explanation:

First of all, lets define the multiplication property of equality

The multiplication property of equality states that if one side of an equation is multiplied with any number the other side is also multiplied with the number.

Given equations are:

$(x+2)(x-2) = 0\\m+7 = -12\\\frac{b}{-2} = 18\\-3+y = 7$

By observing the equations we can see that only third equation has a fraction in it so it has to be multiplied with -2 for solution

$\frac{b}{-2} * - 2 = 18*-2\\b = -36$

Hence,

Multiplication property of equality can be used to solve: $\frac{b}{-2} = 18$

Lisa buys a television for $4185. if the sales tax is $292.95. what percent is sales tax?

Romashka-Z-Leto [24]

Answer:

Sales tax = 7%.

Step-by-step explanation:

Let x be the percent of sales tax.

We have been given that Lisa buys a television for $4185. The sales tax is $292.95.

We need to figure out x such that x percent of 4185 equals to 292.95. Let us represent this information in an equation.

$\frac{x}{100}*4185=292.95$

Let us multiply both sides of equation by 100.

$100*\frac{x}{100}*4185=100*292.95$

$x*4185=29295$

$x=\frac{29295}{4185}$

$x=7$

Therefore, sales tax is 7%.

Let us cross check our answer by calculating 7% of 4185.

$7\%\text{ of } 4185=\frac{7}{100}\times 4185$

$7\%\text{ of } 4185=0.07\times 4185$

$7\%\text{ of } 4185=292.95$

We can see that 7% of 4185 is 292.95. Hence, sales tax is 7%.
