Step-by-step explanation:
Ans: B
The method (a^2-b^2) is considered as one of the many ways of factorisation.
Hope this can help.
let x be the number of adults
let y be the number of child
3.5 x + 2.25 y = 50
x+ y =20 y = 20 - x
3.5 (20-y ) + 2.25 y = 50
70 - 3.5 y +2.25y =50
70 -1.25 y = 50
y = 16
and x = 4
Answer:
l and 3, 2 and 4, 5 and 11, 8 and 16
Step-by-step explanation:
you would put the one over 3 then 2 over 4 then 5 over 11 then 8 over 16 then put it in a equation and solve
Answer:
Step-by-step explanation:
