Answer: x = -2
Step-by-step explanation: 3x+7 = -x-1; add 1 to both sides: 3x+8=-x; subtract 3x from both sides: 8 = -4x; divide by -4 on both sides: -2 = x
Answer:
17.4 (3 Significant numbers)
Step-by-step explanation:
Formula for finding Cylinder : π r² h
So your 5453 = π x (20cm ÷ 2)² x height
To get height (tallness), divide 5453 by (100π)
Depending on your π, your answer should be either, 17.366 / 17.35 / 17.357 which all rounds up to 17.4 if your question asks for 3 significant figures
It is not because 30×10^4 is 300,000.
The answer would then be...
30×10^5
Hope this helps!
Answer:
x = 0.25
Step-by-step explanation:
If y varies inversely with x, then:

Given:
Substitute the given values into the found equation and solve for k:



Therefore:

To find the value of x when y = 3.2, substitute y = 3.2 into the found equation and solve for x:
