Answer: , where x= width of the rectangle ( in inches).
Step-by-step explanation:
Let x= width of the rectangle ( in inches).
Then its length = 2x-7 ( in inches).
Area of rectangle = Length × width
= (2x-7) × (x)
= 2x × x -7 ×x
= 2x²-7x
The area of the rectangle is 72 square inches.
Hence, the equation that represents the given situation :
Answer:
The answers to all the questions are given below.
Step-by-step explanation:
8)The ratio of the numbers 27 feet and 54 yard
1 foot = 0.3333 yard
27 feet = 9 yard
Required ratio = = 0.167
9)A 17 ounce bag costs $5.27.
Hence cost of 1 ounce bag = = $0.31
12)For trip of 240 miles ,it uses 8 gallons.
13)1 quart = 0.25 gallons
Hence the ratio would be
14)1 pound = 0.0005 tonnes.
Hence the ratio would be
19)1 week = 7 days
So the ratio would be
These are the required ratios
