Zoe spent 5/10 of an hour jumping rope. Write the amount of time she spent jumping rope as a fraction in simplest form ONLY THE SMARTEST PERSON IN THE WORLD COULD ANSWER THIS PLZ HELP!

...

Step-by-step explanation:

its 1/2

5/10 in simplest form is 1/2

so this is how long she took as a fraction...

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.

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.
