How do i solve “if someone is 54 inches tall how tall are they in meters”

Hi there!

1 meter is equal to 39.3701 inches

In order to find you answer, you'll need to use the cross product method:

1 meter = 39.3701 inches

x            = 54 inches

(1 × 54) ÷ 39.3701 = x

54 ÷ 39.3701 = x

1.37159926 = x

1.37 ≈ x

Your answer is : If someone is 54 inches, they are about 1.37 meters tall.

There you go! I really hope this helped, if there's anything just let me know! :)

the answer is b

see explanation

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
