0=7x+14-4
0=7x+12
7x=-12
x=-12/7
Answer:
Do the opposite operation
Step-by-step explanation:
If there is a coefficient like 3x, you have to divide the 3 on both sides. This is because 3x is equivalent to 3*x. The opposite of multiplication is division.
Answer:
Im not sure about 20 but 22 is 48
Step-by-step explanation:
4×96 =384
384÷8 = 48 orange per classroom
It is about $10
round $3.85 to $4
round $3.06 to $3
round $2.79 to $3
add them together $4+$3+$3=$10
The original volume of the balloon is given by:
V1 = (4/3) * (pi) * (r ^ 3)
Where,
r: radius of the sphere.
Substituting values:
V1 = (4/3) * (pi) * (1 ^ 3)
V1 = (4/3) * (pi) * (1)
Then, the volume of the current sphere is:
V2 = (4/3) * (pi) * ((1 + 2 * (1)) ^ 3)
V2 = (4/3) * (pi) * ((1 + 2) ^ 3)
V2 = (4/3) * (pi) * ((3) ^ 3)
V2 = (4/3) * (pi) * (27)
The relation of volumes is:
V2 / V1 = ((4/3) * (pi) * (27)) / ((4/3) * (pi) * (1))
V2 / V1 = 27/1
Answer:
The ratio of the current volume of the balloon to the original volume of the balloon is:
27: 1
