Answer:

  • 11xy + 4x²t

Step-by-step explanation:

<u>We know that:</u>

  • Given expression: 7xy - x²t + 4xy + 5x²t

<u>Solution:</u>

  • 7xy - x²t + 4xy + 5x²t
  • => 11xy - x²t + 5x²t
  • => 11xy + 4x²t

Hence, the simplified expression is 11xy + 4x²t.

A store has a sale with 20% off every item. When you enter the store, you receive a coupon that states that you receive an addit
mr_godi [17]
No, because let’s say for example that something cost $100.00 so you take 20% (or $20) off of the 100 and you’re left with $80.00. Well then you have your 10% off coupon so you take 10% off of 80, which is 8 dollars. So now you’re at $72.00.

But if we just took off 30% from 100 originally, you would be at $70.00

So no it wouldn’t be the same. If you wanted to check the idea yourself just use different numbers and see if they match at the end.

Plz help what is 8 t.=_______lb.?
larisa86 [58]

Answer:

16,000 lb.

Step-by-step explanation:

For every ton, it equals 2,000 pounds. So to find how many pounds is in 8 tons, just multiply 2,000 by 8. This would give you 16,000 pounds!

This is of course using the U.S. tons, so if you want to convert it for metric tons it would be 17,632 since 1 metric ton = 2204.

I hope this was able to help!

Explain how to divide 3/4 ÷ 3/8 by using reciprocal of 3/8​
sertanlavr [38]

The reciprocal of 3/8 would be 8/3 (basically reversing the numbers).

When dividing fractions, you can just multiply the first fraction by the reciprocal of the second fraction instead of dividing by the second fraction.

3/4 ÷ 3/8

= 3/4 × 8/3

Simplifying gives us the final answer:

= 2

Let me know if you need any clarifications, thanks!
