Answer:
Yes.
Step-by-step explanation:
Set the equations equal to each other to determine their equality.
-4[3(x - 7)] = 6(14 - 2x)
Distribute the 3 and the 6 into their respective parenthesis.
-4[3x - 21] = 84 - 12x
Distribute the -4 into the brackets.
-12x + 84
Rearrange the equations.
84 - 12x = 84 - 12x
Since the equations come out to be the same thing on both sides so that any value satisfies it, the equations are equivalent.
Answer:
Step-by-step explanation:
<u>Volume of a cylinder:</u>
<u>Container A</u>
- r = 10 ft, h = 11 ft
- V = π*10²*11 = 1100π ft
<u>Container B</u>
- r = 7 ft, h = 19 ft
- V = π*7²*19 = 931π ft²
<u>After pump out the container A has the level of:</u>
<u>Level % in the container A:</u>
- 169π/1100π×100% = 15.4% rounded to the nearest tenth
7,458 is the answer because 12% of 8475 is 1017 8475-1017 = 7458 so being the answer.
The circumference formula is pi times diameter. So first divide 56.52 by 3.14 and that is 18. So the diameter is 18
