Solve for x.
Leto [7]

Answer:

x < 4

Step-by-step explanation:

Step 1: Subtract 10 from both sides.

  • -8x + 10 - 10 > -22 - 10
  • -8x > -32

Step 2: Divide both sides by -8 and flip the inequality sign.

  • \frac{-8x}{-8} > \frac{-32}{-8}
  • x < 4

Therefore, the answer is x < 4.

Have a lovely rest of your day/night, and good luck with your assignments! ♡

Answer in fraction form = 9/8

Answer in decimal form = 1.125

note: the improper fraction 9/8 converts to the mixed number 1 & 1/8

To get this answer, we divide both sides by 8 to isolate n. The expression 8n really means "8 times n". We divide to undo the multiplication.

Randy buys a pair of shoes that were originally priced at $147. He receives a 35% discount and pays 8.5% sales tax. How much doe
maksim [4K]
Begin by subtracting 35% from 100%, giving 65% which is equivalent to 0.65
Then multiply
147 * 0.67 =  98.49
Now for a sales tax you would want to multiply by 108.5% (or 1.085) as you are paying the previous price and them some
98.49 * 1.085 = <span>106.86165
You can round to the second decimal place since you can't have a monetary value less than a penny
your answer would be $106.86
