Lets say a balloon = x
4x + 5x + 6x = 120
15x = 120 (divide each side by 15)
15x/15 = 120/15
x = 8
blue balloons = 4x = 4(8) = 32
red balloons = 5x = 5(8) = 40
yellow balloons = 6x = 6(8) = 48
Let your age be 'X'
Then the age of your brother will be
The age of your sister is 10, but can also be written as an expression (since it is the age of your brother +6)
Now we get the following equation:
Subtract 6 from both sides
Multiply by 3
Hence, the answer on your question (which is your age) is 12.
Are you serious? We are not doing your homework. Where's your effort?
Answer:(-2,8) (-1,5) (0,2) (1,-1) (2,-4)
Step-by-step explanation:
The volume of a rectangular prism is simply the product of the length, the width, and the height. This is from the general formula for the volume of a prism which is the product of the area of the base and the height. If you know the measurements of the length, width, and height, you can easily calculate the volume.
