1) we calculate the discount
discount=$220 -$194.7=$25.3
2) now, we calculate the percent of the discount on this game system by the rule of three.
$220--------------------------100%
$25.3--------------------------- x
x=($25.3 * 100%) / $220=11.5%
The discount was. 11.5%.
She gets 1/9 of the $117, or $13, while Isabella gets the other $104.
This holds to the ratio as $13 is 1/8 of $104.
The first 4 (.4) is 10x bigger than the second 4 (.04)
If quadrilateral NOPQ is a parallelogram then:
NO = PQ
5 x + 12 = 7 x - 8
12 + 8 = 7 x - 5 x
20 = 2 x
x = 20 : 2
x = 10
NO = 5 * 10 + 12 = 50 + 12 = 62
Answer: d. 62
<span>In order for an equation to have an infinite number of answers, the simplified equation should be x=x. In evaluating the above equation, -3 inserted in the box results in this simplified equation. The answer is therefor #1: -3</span>
