Answer:
The answer is z = 34.
Step-by-step explanation:
1) Simplify 2 + 8 - z to 10 - z.
2) Subtract 10 from both sides.
3) Simplify - 24 - 10 to -34.
4) Multiply both sides by -1.

Answer: yes
Step-by-step explanation:
Answer:
No
Step-by-step explanation:
To find out if (4,10) is a solution to the system, we plug in the values of x and y into each equation.
1:
2:
As you can see, (4,10) only satisfies ONE equation, not both. Therefore, the answer is no, it's not a solution.
Answer:
16) 9ft, C
17) 1440 cm^3, D
18) 314 m^2, B
Step-by-step explanation:
16) 18 / 6 = 27 / x
18x = 162
x = 9 (C)
17) 24 / 1,920 = 18 / x
24x = 34,560
x = 1440 (D)
18) Surface Area of a sphere = 4 * pi * radius^2 (4r^2)
SA = 4pi(5)^2
SA = 4pi25
SA = 100pi
SA = 100(~3.14)
SA = 314 (B)
