Kealyn is reading a book. the books thickness is 31 millimeters. which is the correct thickness in centimeters.

We are given

The books thickness is 31 millimeters

we know that

1 millimeters=0.1 centimeters

so, we can write

31 millimeters=31*1 millimeters

so, we can 1 millimeters

we get

31 millimeters=31*0.1 centimeters

now, we can multiply

we get

31 millimeters=3.1 centimetersAnswer

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
