Imagine that you have 8 apples which you want to hand out to 2 people. You want each person to get an equal amount of apples, so you decide to
give 2 apples at a time (one apple to each), until you run out or
you don't have enough to give each of the 2 people another apple. Notice
that each time you give out 2 apples, you have to subtract 2
from the total left over, and each person gets one apple. Let's
see what happens:
1. 8-2=6 -- each person now has 1 apple, and there are 6 more to hand out;
2. 8-2-2=4 -- each person now has 2 apples, and there are 4 more to pass out;
3. 8-2-2-2=2 -- each person now has 3 apples, and there are 2 more to distribute;
4. 8-2-2-2-2=0 -- each person now has 4 apples and there are no more apples to pass out.
Then you hand out 8 apples to 2 people and each of the get 4 apples. This meansthat 8÷2=4.
We want to solve
Subtract 2/(2x+1) from each side.
Add 1/4 to each side, and simplify the left side.
Cross multiply.
4(x - 2) = 1(2x + 1)
4x - 8 = 2x + 1
Simplify and solve for x.
4x - 2x = 1 + 8
2x = 9
x = 9/2 or x = 4 1/2.
Answer:
Area of parallelogram = base x height
area of large parallelogram
8 x 12 = 96
area of small parallelogram
4 x 6 = 24
96 - 24 = 72
the area of the shaded region is 72 m^2
Imaginary numbers are taught in high school algebra, which I think imaginary numbers are taught in 10th or 11th grade.
Answer:
The answer is simply 26,25/3 which gives that each book costed 8,75 dollars assuming of course that all books have the same price.
