Find the greatest common factor of -30 x^4yz^3 and 75 x^4z^2
? z^?

15x^4z^2

Step-by-step explanation:

We need to break each term into the smallest factors

30 = 3*10 = 3*2*5

75 = 3*25 = 3*5*5

-30 x^4yz^3 = -3*2*5 * yzzz

75 x^4z^2 = 5*5*3zz

What common factors are in each term

3*5**zz

15x^4z^2

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
