The sum of two numbers is 44 and their difference is 14. What are the two numbers? Let's start by calling the two numbers we are looking for x and y.
The sum of x and y is 44. In other words, x plus y equals 44 and can be written as equation A:
x + y = 44
The difference between x and y is 14. In other words, x minus y equals 14 and can be written as equation B:
x - y = 14
Now solve equation B for x to get the revised equation B:
x - y = 14
x = 14 + y
Then substitute x in equation A from the revised equation B and then solve for y:
x + y = 44
14 + y + y = 44
14 + 2y = 44
2y = 30
y = 15
Now we know y is 15. Which means that we can substitute y for 15 in equation A and solve for x:
x + y = 44
x + 15 = 44
X = 29
Summary: The sum of two numbers is 44 and their difference is 14. What are the two numbers? Answer: 29 and 15 as proven here:
Sum: 29 + 15 = 44
Difference: 29 - 15 = 14
Answer:
Step-by-step explanation:
volume of one cube = ½×½×½ = ⅛ cm³
volume of prism = 5×3×6 = 90 cm³
90/(⅛) = 720 cubes to fill the prism.
volume of bottom layer of cubes = 5×3×½ = 7.5 cm³
7.5/(⅛) = 60 cubes on the bottom layer
Each layer is ½ cm in height
6 cm × (1 layer)/(½ cm) = = 12 layers
perimeter = 2×5 + 2×3 = 16 cm
