5*4*6=120
4+(6+9)=19
675+9=75
You simply divide numerator by denominator
818/1320 = 0.619
1742/2540 = 0.685
396/1220 = 0.32
hope this helps ;3
Answer:
x = 49
Step-by-step explanation:
Given
=
( cross- multiply )
5(x - 16) = 3(x + 6) ← distribute parenthesis on both sides
5x - 80 = 3x + 18 ( subtract 3x from both sides )
2x - 80 = 18 ( add 80 to both sides )
2x = 98 ( divide both sides by 2 )
x = 49
The formula for the volume of a cube is:
v=s³
Where v=volume and s=the length of a side
Since we know that the length of a side of the gift box is 15cm, we can solve for the volume.
v=15³=3375cm³
Answer: V=3375cm³
