9 times it will be 98 rhr
10) 7(2m+3)
11) 3(3r-1)
12) 2p(5q+4)
Of means multiply.
30%=0.3
30*0.3=9

First of all, I find it easiest to write n equation.
3 / 15 x 8 =
Now that we have an equation, we can figure out a solution.
3 / 15 = 5
5 x 8 = 40
So 8 DVD's would cost $40.00.
Volume of a cone = pir^2h/3
so substitute what you know
1,102.14 = 3.14(r^2)(13/3)
divide by 3.14
351 = r^2(4.3333)
divde by 13/3
81 = r^2
r = 9 inches
