Brian is 1 meter 87 centimeters tall. Bonnie is 58 centimeters shorter than Brian. Betina is 26 centimeters taller than Bonnie.

Blizzard [7]

Answer:

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

Step-by-step explanation:

let

x ----> Brian's height

y ----> Bonnie's height

z ----> Betina's height

we know that

$1\ m =100\ cm$

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

$x=187\ cm$

$y=x-58$

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

mars1129 [50]

Answer:

D. F'(x) = 5(x + 2)

Step-by-step explanation:

F(x) = x/5 - 2

y = x/5 - 2

x = y/5 - 2

5x = y - 10

y = 5x + 10 = 5(x + 2)

F'(x) = 5(x + 2)
