The length of a rectangle is 3ft less than twice the width, and the area of the rectangle is 77ft^(2). Find the dimensions of the rectangle.

Answers

Answer 1

Answer:length=11 and the width is 7

Step-by-step explanation:

To find the area of a rectangle it’s widthxlength and the only numbers that make up 77 are 11 and 7 and 77and 1. So it would have to be 11 and 7 also if you plug it in (2(7)-3=11 and that works. Hope this helps <3

Anthony bought a PlayStation 4 on sale for $295, what is the percent of change from the original price of the PlayStation 4 video game system?


PlayStation original price: 400

Answers

Answer:

27% of change

Step-by-step explanation:

If you get a calculator type in 400 multiplied 73% you get $292. Its not the exact answer because there is no exact answer for this but..... There is always tax you have to pay for an item and so here Anthony would have to pay $3 for tax.

If 27% is not one of the answers the other answer that is possible is 30% and you would get a total of $280 and pay $15 for taxes.

Hope this helps :)

The answer would be a 27% change
