£990 is divided between gavyn, alex & peter so that gavyn gets twice as much as alex, and alex gets three times as much as peter. how much does alex get?

297

Step-by-step explanation:

let's call what Peter gets "x" ,since Alex gets three times as much as Peter we can call it 3x and Gavin 6x because he got 2 times more than Alex

adding all of them together is £990 so

6x + 3x + x = £990

10x = £990

x = £99

Alex got 3x therefore the answer is 3 × 99 = 297

46

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm
