Answer:
x =
Step-by-step explanation:
We have the equation: 3 +
= 
Move the constant (in this case the constant is 3) to the right side of the equation, changing its sign
=
- 3
Calculate the difference.
= 
Divide.
(when dividing two fractions, you can change it to a multiplication problem by switching the numerator and denominator of the divisor.)
So, we get the equation
x
which is
.

Answer:
D
Step-by-step explanation:
It is c, 2 -4 no solution
We can solve this problem by first solving for the total
volume of the cube. The formula for volume of cube is given as:
V cube = s^3
Where s is the length of one side which is equivalent to
2 inches. Therefore:
V cube = (2 inches)^3
V cube = 8 cubic inch
Assuming that all the pebble fills the cube without any
spaces, then the total weight of the pebbles in the cube would simply be:
Total weight = 0.5 lb per cubic inch * 8 cubic inch
Total weight = 4 lb
Therefore, the total weight of the pebbles in the cube is <u>4
lbs</u>.
