how so you solve 5x+27=9(x+3)-4x and is this a conditional equation, an identity, or an inconsistent equation

Mathematics

Vikentia [17]3 years ago
5 0

To solve this, follow these steps:

5x + 27 = 9 (x+3) - 4x

Distribute the 9 within the parenthesis:

5x + 27 = 9x + 27 - 4x

Then combine like terms:

5x + 27 = 5x + 27

These two then cancel each other out completely.

This is an identity because an identity in math is when both equations equal each other, which is shown above.

Hope this helps!

This item is $9000 dollar and it is 90% off how much is the item? Step by step?
Daniel [21]

Answer:

The item costs $900 after the 90% off.

Step-by-step explanation:

After the 90% off discount, the item costs (100% - 90%) the cost of the original price.

Hence, \$9000 \cdot (100\% - 90\%)

= \$9000 \cdot 10\%

= \$900

Hope this helped!

The Ipad that Ms. Hopham would like to buy for research is $1,299. This week it is on sale for $990, and the sales tax is 6%. Ho
Firdavs [7]

Turn the percentage into a decimal.

6% = 0.06

Multiply.

990 * 0.06 = $54.9 (sales tax)

Add.

990 + 54.9 = $1,049.40 (total price)

Best of Luck!
