Answer: x = -4

Step-by-step explanation:

first, we remove the parentheses.

3x - 12 + 2x = 7x + 10 + 2x - 6

then, we cancel equal terms.

3x - 12 = 7x + 10 - 6

then, we calculate.

3x - 12 = 7x + 4

next, we move the terms.

3x - 7x = 4 + 12

then, we collect like terms and calculate.

-4x = 16

finally, we divide both sides.

x = -4

Aisha went shopping for a new video game because of a sale. The store was offering a 5% discount. If the price on the tag was $2
Anastasy [175]

Answer:

$25.65

Step-by-step explanation:

Since we are applying a discount to a price tag, we will be <u>decreasing</u> the amount of that price tag.

In this case, we will be taking 5% off of $27. This means that our new price tag will be 95% of what it originally was. To find the answer, we must first change 95% into a decimal.

95% -> \frac{95}{100} -> 0.95

Next, we multiple $27 by 0.95 as shown below:

27(0.95)

Our answer will be:

$25.65
