Y would equal 12 if x were to equal 4. You can think of it as a proportion.
We are trying to find the average speed of the plane, which is mph, or 
. Using proportions, we can find the average speed of the plane in mph:
- Use the information from the problem to create a proportion. Remember that we are looking for mph, so we will call that
.
- Multiply the entire equation by
- Divide both sides of the equation by
to clear both sides of the mile unit
The average speed of the plane is 300 mph.
First you plug in the missing values
y=3 x=4 z=2
3÷2×4-2
than you solve
the answer is 4
Just a shot in the dark: 9*30 and 9*8?
Elena packed 48 cubes.
Each cube has an edge of 1 centimeter.
The number of layers that Elena can make depends on how each layer is arranged and depends on how many cubes are there in a layer.
Assume that each layer has only 1 cube, then there are 48 layers.
