Kate has made 40 free throws in basketball games this year. That is 90% of the free throws she has attempted. To find the total number of free throws she attempted, Kate wrote the equation 90/100 ?/40, What error did Kate make?

Total Free Throws Attempted = 25

Step-by-step explanation:

From the statement we can say:

20 free throws is 80% of the total attempted

80% to decimal is:

80/100 = 0.8

If total attempted is N, we can say:

20 is 80% (0.8) of N

We can now write an algebraic equation:

20 = 0.8N

We simply solve this for x, that is the number of free throws she attempted:

20 = 0.8N

N= 20/0.8

N=25

Kate attempted 25 free throws in total.

Kate wrote the equation 80/ 100 = N /20 .It is wrong.

It will be 80/100=20/N

Hope it helps.

Thanks my answer.

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.
