. Jax is at the gym about to lift weights. He finds the bar already has weights on it, but some are not labeled. When he lifts the bar, he notices that the left side is lighter than the right side. Which of the following is a possible value of one of the unknown weights, x, on the bar?

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

1. 3. can also be expressed as (22/7)

2. -4.5

3. 3.6

pls mark as brainliest

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5
