8/2 is 4 and -10 + -2 is -12 because your adding two negatives
There's no slope, so it's impossible to answer your question. I'm sorry.
4 / 0.80 = 12 / x...cross multiply
4x = 0.80 * 12
4x = 9.6
x = 9.6 / 4
x = 2.4.....12 apples cost $ 2.40
First, we must solve for the radius of the sphere:
V=



r=(3

)

r=(3*

)

r≈5.99
Second, we must solve for surface area:
A=4


A=4*

*

A≈450.88
1. A
I hope this helped! This is because the division of numbers and factors are equal to this.
