<h3>
Answer: $142.80</h3>
==========================================================
Explanation:
To get this answer, we double the 71.40 to get 142.80
You can think of it like an equation and we multiply both sides by 2
4 jeans = 71.40 dollars
2*(4 jeans) = 2*(71.40 dollars)
8 jeans = 142.80 dollars
------------
Or you could solve it like this
(4 jeans)/(71.40 dollars) = (8 jeans)/(x dollars)
4/71.40 = 8/x
4x = 71.40*8
4x = 571.2
x = 571.2/4
x = 142.80
------------
Yet another way to solve is to first find the unit rate
4 jeans cost 71.40, so that must mean 1 pair of jeans cost 71.40/4 = 17.85 dollars. This is the unit rate since "unit" means "one". It's the price per pair of jeans.
Multiply that by 8 to find out how much 8 pairs will cost, and we get 17.85*8 = 142.80
Answer:
B) >
Step-by-step explanation:
We can convert the fractions into decimals to see which is greater.
3/5 = 0.6
5/10 = 0.5
From this, we can see that 3/5 is greater than 5/10, so the sign is >.

The area of one window is 15 ft²
Step-by-step explanation:
Area of a trapezoid window can be calculated as ;
1/2(a+b) h where
a=outside edge length
b=inside edge length
h=length across
Given that ;
a=1 ft
b=5 ft
h=5 ft
Area= 1/2( 1+5)5
Area= 1/2 (6)5
Area=3*5 =15 ft²
