The swamp middle school basketball team purchased new equipment and uniforms. The total cost of the equipment was $245 and each uniform cost $21. If the total cost of their purchase was $518, how many uniforms did they buy? Create an equation for this situation.

Step-by-step explanation:

Step one:

given data

total cost of equipments= $245

cost of each uniform=$21

Total purchase = $518

Step two:

The amount spent on uniform is total purchase minus the total cost of equipment

=518-245

=$273

Hence the total cost of the uniform is $273

if one will cost $21, then the number of uniforms they bought is

=273/21

=13 uniforms

25 uniforms

Step-by-step explanation:

518/21= 24.6 round to 25

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
