Answer:
Step-by-step explanation:
Total number of boxes of cookies that Kendal bought to bring to the party is x.
Each box contains 12 cookies. This means that total number of cookies in x boxes would be
12 × x = 12x
She decides to keep two boxes for herself. This means that the total number of cookies that she kept for herself would be
12 × 2 = 24 cookies
She brings 60 cookies to the party.
The equation that can be used to find the number of boxes, x, Kendal bought would be
12x = 24 + 60
12x = 84
x = 84/12 = 7 boxes
This is a linear equation
y=mx+b
y=50x+400 (when x equals the number of hours played)
1000=50x+400
*first, isolate the variable (x)
-50x=-1000+400
*divide by -50 to get x by itself
x=20+8
The answer is x=28
Do the volume of a circle then multiply by the length of the cylinder
area of a circle =

diameter/2 = radius
so 4^2 = 16 16*3.14 = 50.24
50.24*(4*3) = 50.24*12 = 602.88
Therefore
