Answer:
x = 15.75
Step-by-step explanation:
I'm going to assume you mean solve for x so:
Direction wise I would say southwest, but numerically I would say 7 blocks west and 8 blocks south.
The shaded part is four little blocks, and its area is ' 1 '.
So the area of each little block is 1/4 .
The part with crosses covers two little blocks.
So its area is (2 x 1/4) = 1/2 .
For this case we have the following equation:
c + b = 55
Where,
c: number of CDs
b: number of books
For c = 30 we have:
30 + b = 55
From here, we clear the value of b.
We have then:
b = 55-30
b = 25
Note: observe in the graph that when the value of c is 30, the value of b is 25.
Answer:
the amount Alison may spend on books in March if she spends 30 on CDs is:
b = 25
