Answer:
726
Step-by-step explanation:
Here p = k / q², and 24 = k / 121, or k = 2904
Then p = 2904 / q²
If q = 2, p = 2904 /4 = 726
Short Answer D
Proof
F = 9/5*C + 32 Begin by subtracting 32 from both sides.
F - 32 = 9/5 C Put brackets around the 2 terms on the left.
(F - 32) = 9/5 C Multiply by 5/9 on both sides.
(5/9) * (F - 32) = 5/9 * 9/5 * C
(5/9) * (F - 32) = C
The last one is the answer.
Answer:
-12
Step-by-step explanation:
To evaluate the expression the known value of a = -8 can be substituted in so the equation becomes -8 - 4.
From there the subtraction can be completed which equals -12. This can be visually seen on a number line if you look at -8 and move left 4 spaces.
