Answer:
5
Step-by-step explanation:
The clothing store already sold $300 .
They need to sell x jeans to get to $500.
$500 - $300
$200
They’re $200 short of their goal.
A pair of jeans cost $40
Therefore x40 = $200
x = 200/40
x = 5
So ,they need to sell 5 pairs of jeans to hit their $500 target
Answer:
Helena gave the answer as (7y²z + 6yz²- 5 - 3yz² + 2) which is equivalent to (7y²z + 3yz² - 3).
Step-by-step explanation:
Misha's group was asked to write an expression equivalent to
7y²z + 3yz² - 3
When Mr. Chen checked their answers, he found only one to be correct.
And she was Helena.
Helena gave the answer as (7y²z + 6yz²- 5 - 3yz² + 2) which is equivalent to (7y²z + 3yz² - 3).
Because, (7y²z + 6yz²- 5 - 3yz² + 2)
= 7y²z + (6yz² - 3yz²) - (5 - 2)
= 7y²z + 3yz² - 3 (Answer)
