A set of children’s blocks contains three shapes: long, flats, and cubes. There are three times as many longs as cubes and 30 fewer flats than longs. if there are 600 blocks in all how many Long’s are there

There are 270 longs

Step-by-step explanation:

Equations

We must write the problem into a mathematical model that allows us to apply the properties of basic algebra and solve for the variable which must be adequately set up.

We have three unknowns: the number of long blocks, flats blocks, and cubes. The conditions are given:

For the equation to be easier solved, let's set the variable as the number of cubes:

x = number of cubes

Considering the first condition, we have

3x = number of longs

3x-30 = number of flats

And finally:

Joining like terms:

Solving for x

Therefore, there are 3x = 3*(90) = 270 longs

there are 270 longs

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.
