20 because if you take 20 half it that would be 10 then take away 4 that would then equal 6.
Answer:
Choice A
Step-by-step explanation:
In this case, you already used 310 minutes out of 500 minutes monthly. So the remaining time for your cell phone should be: 500 minutes -310 minutes= 190 minutes.
You still have 1 week this month, that means the 190 mins time must be divided into 1 week or 7 days. Then the duration you of cell phone use for each day should be: 190 minute/7days= 27.14 minutes/day

3y=15-4x
y=5-4/3x
so the answer is 5
The area of the roof is 1984 sq. ft. 1984 square feet of roofing is needed for the roof of a building that is 32 ft wide and 62 ft long.
Given, the length of the roof is 62 ft long and the width of the roof is 32 ft wide. Therefore, the area of the roof is length * width.
Area of the roof = length of the roof * width of the roof
Area = 62 ft * 32 ft
Area = 1984 sq. ft
Here, also given the slope of the roof is 1:2 which indicates the ratio of rise and run.
Slope of the roof = Rise / Run = 1 / 2
Then, the slope factor is
=
= 0.04167
