Answer:
22 Feet
Step-by-step explanation:
All the lengths of a square are the same length.
The area of a square is the length times the width. The length and the width are the same measurement. So, we are looking for the square root of 479.
21.88606863 is as far as my calculator goes. This is an irrational number. That means that it never repeats or terminates as a decimal. They tell us to answer to the nearest foot. That would be 22 feet.
This has to be 20 Characters long to tell you the answer, but the answer is A
Answer:
$20
Step-by-step explanation:
Since we are talking about the unknown cost of a shirt AND a sweater, we are dealing with 2 unknowns. However, we can only have one unknown in a single equation or we cannot solve it. The cost of the sweater is based on the cost of the shirt, so the shirt will be our "main" unknown.
Cost of the shirt: x
Since the sweater is $5 more than (this is addition) twice (that is 2 times) the cost of the shirt, the expression for the sweater is 2x + 5
The cost of both is (equals) 65.
x + 2x + 5 = 65 and
3x + 5 = 65 and
3x = 60 so
x = 20
The shirt cost $20 so the sweater had to cost 65 - 20 = 45
