Mary has spent $68 on shirts and pants at a local garage sale. If Mary bought 26 items in total, Solve a system of equations to find how
many shirts (x) and pants (y) she bought if shirts cost $2 and pants
cost $3.

The answer is 16 pairs of pants and 10 shirts

16y+10x= a total 26 items

16*3=48

10*2=20

20+48=68

the answer i think is a)

step-by-step explanation:

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.
