The weight of an object on a particular scale 155. 2lbs the measured weight May very from the actual weight by the most 0.4 lbs what is the range of actual weight of the object

D. 154.8 ≥ x ≤ 155.6

Step-by-step explanation:

We are told that it varies the most by 0.4, so this means that it cannot be a value less than 154.8 or exceed a value greater than 155.6.

Since it says by most, we know it is an inequality that is greater than/less than or equal to. x is the weight of the object.

Subtract 0.4 from 155.2 and you get 154.8, which is the minimum value. You obtain the inequality 154.8 ≥ x.

Add 0.4 to 155.2 and you get 155.6, which is the maximum value. You obtain the inequality x ≤ 155.6.

We can take these two inequalities to create a compound inequality that represents the weight of the object.

Our final answer would be D. 154.8 ≥ x ≤ 155.6

y = 0.77(x)

step-by-step explanation:

the jacket retains this value after 23% cut or retains 77% of original value. plug original 87 jacket price for x and the remaining value should be y.
