Use the diagram to find the value of x and y​

x = 6

y = 15

Step-by-step explanation:

We can find the value for x and y using similarity ratio

8/12 = 10/y cross multiply expressions

8y = 120 divide both sides by 8

y = 15

12/(x+12) = 10/15

180 = 10x + 120 subtract 120 from both sides

60 = 10x divide both sides by 10

6 = x

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
