A bottle of water, soft drink and juice are shown below. The bottles of water weighs 8 kilograms (kg), together the soft drink and the juice weigh the same as the bottle of water. If the soft drnkweighs 2kg more than the juice, then what is the mass of the juice bottle.

46

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm

the graph line crosses the x axis at both -6 and -2, so the answer would be the second one.
