−10x + 1 + 7x = 37
-10x+7x+1=37
-3x+1= 37
Move +1 to the other side. Sign changes from +1 to -1.
-3x+1-1= 37-1
-3x=36
Divide by -3.
-3x/3= 36/-3
x= -12
Answer : x= -12
To find this answer you need to find the area of the whole cake and divide it by 8. To find area of a circle, you need the formula (pi)*r^2. The radius is the diameter divided by two. Your final formula would be (pi)*8^2. This is approx. 201.06 in^2. Divide this number by 8, and you have your answer. I got 25.13 in^2.
