How many groups of Two-thirds are in Three-fifths?

9/10 of a group

Step-by-step explanation:

Take 3/5 and divide by 2/3

3/5 ÷ 2/3

Copy dot flip

3/5 * 3/2

9/10

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.
