Composite, as there are multiple factors of 36.
(1,2,3,4,6,9,12,18 and 36)
<span>'x' can be anything. There's no information here to say that it must be
one thing or another. You can't find 'x', because there is no
equation.
You can probably simplify the fraction by doing some factoring, but
there's
no way to tell a value for 'x'. As long as 'x' is not -4, it can be anything, and
its value determines the value of the fraction.</span>
9-4=-5 would be the smallest answer
It's rational
Rational numbers are numbers that you can put into the form of a/b.
Answer:
(c) $80
Step-by-step explanation:
Each discounted price corresponds to the original price multiplied by a factor related to the discount. For a discount fraction of 'd', the multiplier is (1 -d).
This means you can use any of the lines in the table to find the original price.
<u>5% disount</u>: (1 -5%)·p = $76 . . . . where p is the original price
p = $76/0.95 = $80 . . . . . . . the original price
<u>10% discount</u>: (1 -10%)·p = $72
p = $72/0.90 = $80
<u>25% discount</u>: (1 -25%)·p = $60
p = $60/0.75 = $80

<em>Additional comment</em>
The table values for 5% and 10% differ by 5% and $4. That means 5% of the original price is $4. There are two things you can do with this:
- add back that 5% to the 5%-discounted price: $76 +4 = $80
- multiply that 5% by 20 to get 100% of the original price: 20(5%) = 20($4) ⇒ 100% = $80.
