Just 9 and 10 please and show step by step

Step-by-step explanation:

Okay so,

9. m=11/4 or 2 3/4

Bring the 1 and 1/2 to the other side to make the equation,

m=1 1/2 - 5/4  (Solve the fractions)  m= 11/4, or 2 3/4

Do not forget the m=11/4!

10. 28/5 or 5 3/5

Make 9 and 1/3 to a mixed number, which is 28/3, then...

28/3 divided by 5/3n, since its already in a mixed number we can keep it the way it is

*use the keep change flip method (kcf)*

keep 28/3 change the division equation to a multiplication one, and flip 5/3n

We can ignore the n since we're still ganna get, n=???

So the equation would look like this

28/3 * 3/5, which will get you to, 28/5 or 5 and 3/5!

*Dont forget to put it as, m=28/5, or m= 5 and 3/5

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
