52. lifting ben is training for football and is
lifting 120 pounds on the bench press. he
can lift a maximum of 180 pounds. write
and solve an inequality to determine
how much additional weight ben can lift.

120 + x = 180

Step-by-step explanation:

subtract 120 from 180 and you get x= 60lbs

that is the sum

step-by-step explanation:

there are no other answers without knowing the variables values

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
