A rectangle has a length six inches less than twice its width. If the perimeter of the rectangle is 54 inches, find the dimensions.
Answers
Answer:
let the width of the rectangle be x inches
then the length would be 2x-6
as perimeter =2(l+b)
putting values in formula
perimeter = 2(2x-6+x)
p= 6x-12 but as perimeter p=54inches so
54=6x-12
54+12=6x
66=6x
x=66/6
x=11 inches
width is 11inches and length is 2x-6= 2(11)-6=22-6=16 inches

2. Cells use oxygen faster than it can be replaced so that means that the body wouldn't be able to get the oxygen that is needed throughout the body which leads to the athletes performing poorly.
3. This process will more likely to occur in a short run because your body needs a lot more energy in a short run than in a long walk. The more energy the body need, the more oxygen will be used.

They both mean "move the decimal point 7 places that way ===> ."
So take the 3.82 and do that to it.
If there aren't enough places to move the decimal point far enough,
then add some zeros onto the end of the 3.82 before you move
the point.

The profit of the store is the amount the store makes on top of the cost of
each game sold.
The store's profit is $35.00
Reason:
Theamount Elsie bought the video game = $85.00
The percentage the store charges = 170% of the cost of the game
We have;
Let C represent the cost of the game, we have;
170% of C = 85.00
Which can be expressed as
Therefore;
The cost of the game, C = $50.00
Profit = Selling price - Cost
Therefore, the store's profit, P = $85.00 - $50.00 = $35.00

10(x−2)+15=8x+7
(10)(x)+(10)(−2)+15=8x+7(Distribute)
10x+−20+15=8x+7
(10x)+(−20+15)=8x+7(Combine Like Terms)
10x+−5=8x+7
10x−5=8x+7
Subtract 8x from both sides.
10x−5−8x=8x+7−8x
2x−5=7
Add 5 to both sides.
2x−5+5=7+5
2x=12
Divide both sides by 2.
2x/2 = 12/2
x=6
