A set of children’s blocks contains three shapes: long, flats, and cubes. There are three times as many longs as cubes and 30 fe

kati45 [8]

Answer:

<u>There are 270 longs</u>

Step-by-step explanation:

<u>Equations</u>

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:

There are three times as many longs as cubes
There are 30 fewer flats than longs.
There are 600 blocks in all

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:

$x + 3x+3x-30=600$

Joining like terms:

$7x=630$

Solving for x

$\displaystyle x=\frac{630}{7}=90$

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

Answer: there are 270 longs
