Kai's mom gave him $25 to spend at the book fair. Kai wants to buy as many books as he can. The cost of each book is $3. He also wants to buy one poster for $2. Write an inequality to show how many books he can buy. Highlight your inequality in green. Then, solve the inequality.

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15

      2

  2 is to go somewhat to the top right of a because it is squared    

v= a h/3

t= half of the arc subtended by t.

r= half of the arc subtended by r.  

t+r= half of the arc subtended by t + half of the arc subtended by r= half of 360=180
