Ann, beth and celine wanted to weigh themselves, but the scales they had were broken and would only give readings over 100kg. they decided to weigh themselves in pairs a and calculate their weights from the results.
• ann and beth weighed 119kg
• beth and celine weighed 112kg
• celine and ann weighed 115kg
how much did each of the girls weigh?

Ann - 61 kg

Beth - 58 kg

Celine - 54 kg

Step-by-step explanation:

We use Algebra to solve this. We give unknown to one of them. I have decide to use x here and give it to earn.

Ann = x

Ann + beth = 119 meaning ( 119 - x) = beth

beth = 119 - x

celine + ann = 115 meaning(115 - x) = celine

celine = 115 - x

know we know>

Ann = x

beth = 119 - x

celine = 115 - x

and    beth + celine= 112 kg meaning =>

119 - x + 115 - x = 112

we collect the like terms. 119 and 115 cross the equal sign to the other side.

-x-x = 112 - 119 - 115

-2x = -122

-2x/-2= -122/-2

x = 61

therefore ann has 61 kg

beth has 119 - 61 = 58 kg

celine has 115 - 61 = 54 kg

If you need any clarification or more explanation pls do mention at the comment section.

Hope this helps and if it does pls mark as branliest answer thx.

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2

the answers might not be correct use at own risk

step-by-step explanation:

infinity is the answer
