462 pupils are going on a school trip. A coach can seat 54 children. How many coaches will be needed for the trip?

9

Step-by-step explanation:

Since we know that one coach can seat 54 children we know that we should divide 462/54 which is approximately 8.5 but since we can't leave any behind we should round up to 9.

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

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
