(-1, 2 )
Step-by-step explanation:
Hello from MrBillDoesMath!
Answer: x = +9
Discussion:
-59 = 3x -2 (7x -20) or
-59 = 3x - (2*7)x - 2 ( -20) or
-59 = 3x -14x + 40 or
-59 = -11x + 40. Subtract 40 from each side
-59 - 40 = -11x or
-99 = -11x
or x = + 9
Thank you,
MrB
Answer:
p = 48
Step-by-step explanation:
If p is inversely proportional to the square of q
This is written Mathematically as:
p ∝ 1/q²
p = k × 1/q²
p = k/q²
Cross Multiply
k = pq²
k = Constant of Proportionality
Step 1
We find k
When p is 3 when q was 12
k = pq²
k = 3 × 12²
k = 432
Step 3
determine p when q is equal to 3
p = k/q²
p = 432/3²
p = 48
