Sunaina had three pizzas. She shared the pizzas with her friends. Each of them ate many friends ate 3/7 of a pizza. How many friends ate the pizza

6 friends

Step-by-step explanation:

Take 1/7 multiply by 5/6

9514 1404 393

  7 friends

Step-by-step explanation:

3 pizzas will give 3/7 of a pizza to each of ...

  3/(3/7) = 3 · 7/3 = 7 . . . friends

7 friends ate the pizza.

We assume that Sunaina and her 6 friends constitute 7 friends.

it could be a ..idk tho

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.
