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

Hello,
The 3th angle of the triangle is the supplement of 3x-8:
180-(3x-8)=180-3x+8=188-3x
The sum of all angles of the triangle is 180
180=2x+21+188-3x
==>180=-x+21+188
==>x=21+188-180
==>x=21+8
==>x=29
Answer:
We know that opposite angle are congruent.
So, We found out that x = 7,
So, Putting x = 7 in 10x+10
So, The measure of angle 10x+10 is 80.
Answer:
45 3/10 mph
Step-by-step explanation:
30 1/5 /2 = 15 1/10
15 1/10 x 3 = 45 3/10 mph
1 13/24 is the answer
1 5/6 - 3 3/8 = 1 13/24
