Answer:
3x+4y= -11
Step-by-step explanation:
Answer:
A = 314 inches^2
Step-by-step explanation:
We know the diameter of the glass. We need to find the radius
d = 2r
20 = 2r
Divide each side by 2
20/2 = 2r/2
10 =r
To find the area of the glass
A = pi r^2
A = pi * 10^2
A = pi*100
A = 100 *(3.14)
= 314 in^2
Answer:
r = -1
Step-by-step explanation:
To get r isolated, you have to divide each side by -7
7 divided by -7 is -1, therefore r = -1
Answer:
2
Step-by-step explanation:
8 + 10 = 18
18/9 = 2
Answer:
The measure of z is 17
Step-by-step explanation:
