Explanation:

just 24

Answer 2

Betina is
`1\ m\ 55\ cm` tall

Explanation:

let

x ----> Brian's height

y ----> Bonnie's height

z ----> Betina's height

we know that

`1\ m =100\ cm`

`1\ m\ 87\ cm=100\ cm+87\ cm=187\ cm`

so

`x=187\ cm`

`y=x-58`

substitute the value of x

`y=187-58=129\ cm`

`z=y+26`

substitute the value of y

`z=129+26=155\ cm`

`155\ cm=100\ cm+55\ cm=1\ m\ 55\ cm`

therefore

Betina is
`1\ m\ 55\ cm` tall
