Answer:
24
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
x/2 = 3
x = 3×2
x = 6
Therefore
4x = 4 × 6
4x = 24

Answer: 3.5
Step-by-step explanation:
Given: Dimensions of larger prism = length of 4.2 cm, a width of 5.8 cm, and a height of 9.6 cm.
Dimensions of smaller prism = length of 14.7 cm, a width of 20.3 cm, and a height of 33.6 cm.
Scale factor = 
Since, smaller figure is the original figure and the bigger one is the image.
So, scale factor =
[Taking lengths
Hence, the factor to produce the corresponding dimensions of the larger prism = 3.5
Let q = quarters
Let d = dimes
q + d = 13
0.25q + 0.10d = 2.75
You have two equations and two unknowns.
