Question

Pleaseeeee helpppppppppp

Answer 1

1) 15ft

2) 21m

Explanation:

1) 10ft/4ft = x/6ft

multiply both sides by 6

`(10)/(4) * 6 = (x)/(6) * 6`

60/4 = x

x= 15ft

2) 28m/x = 12m/9m

multiply both sides by 1/28

`(28)/(x) * (1)/(28) = (12)/(9) * (1)/(28)`

1/x = 12/252

1/x = 1/21

by equivalence, x= 21m
