If a math book is 4,458 grams what is the mass of 4 math books in kilograms

The weight of 4 math books is 17.832 kilograms.

Step-by-step explanation:

Given:

weight of math books = 4458 grams

number of math books = 4

1 kg = 1000 grams

4458 grams * 1kg/1000 grams = 4458 kg/1000 = 4.458 kg

4.458 kg * 4 books = 17.832 kg

OR

4458 grams * 4 books = 17832 grams

17832 grams * 1kg/1000 grams = 17832 kg/1000 = 17.832 kg

17.832 kg

Step-by-step explanation:

4 * 4458g = 17832g

17832g * 1kg/1000g= 17.832 kg

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is

answer: he is 272195

step-by-step explanation: all you have to do is multiple 3535 and 77 and it equals 272195
