The ideal length of a particular metal rod is 20.5 cm. the measured length may vary from the ideal length by at most 0.045 cm. what is the range of acceptable lengths for the rod?
a) 20.455 ≥ x ≥ 20.545
b) 20.455 ≤ x ≤ 20.545
c) x ≤ 20.455 or x ≥ 20.545
d) 20.455 ≥ x ≤ 20.545

1. x> -5

2. x< 8

step-by-step explanation:

1. 2x> -10

divide by 2 from both sides of equation.

2x/2> -10/2

simplify, to find the answer.

-10/2=-5

x> -5 is the correct answer.

2. 3x< 24

divide by 3 from both sides of equation.

3x/3< 24/3

simplify, to find the answer.

24/3=8

x< 8 is the correct answer.

i hope this you, and have a wonderful day!
