Hello! -1 - 9 is -10. F = -10. 7 - 9 is -2. G = -2.
F = -10
G = -2
d = 3
Okay, so because d and F are beside each other, we multiply both of the values. Let's plug in the values. -10 * 3 is -30. This is because one negative and one postive make a negative number. Now, we add the number. Because it is negative, we have to go into the negatives more. -30 + (-2) is -32. There. The answer is -32.
Answer:
x = 26
Step-by-step explanation:
There are two numbers and average is the sum of a certain amount of numbers divided by the same amount.
21 × 2 = 42
42 - 16 = 26
x = 26
The volume of a sphere is:
(4/3) * pi * r^3
Plug in the values:
(4/3) * 3.14 * 5^3 is about 523.3 cm cubed.
The answer is (B), 523.3 cm cubed.
