Liam is a tyre fitter.
It takes him 124 minutes to fit 4 tyres to a lorry.
a) How long would it take him to fit 6 tyres to a lorry?
b)
If he works for 93 minutes, how many tyres can he fit?

a) 156

b)3

Step-by-step explanation:

for A, 6 tires is 1 1/2 of 4 tires, so divide 124 by 2 and get 52. Add 124 and 52 and you get 156. for b, divide 124 by 4 and get 26. add 26 3 times and you'll get 98 which is relativity close to 93 so yeah hope that helps

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
