Answer:2.20

Step-by-step explanation:

4x3=12

12/5=2 2/5 of 2.20

The required simplified equivalent expression is given as 8x + 3.

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

here,
Given expression,
=  8x+30/10

Simplify the above expression, as 30/10 = 3
= 8x + 3

Thus, the required simplified equivalent expression is given as 8x + 3.

Answer:

A reasonable measure for the height of the door would be 2.23 meters

Step-by-step explanation:

We use three units of measurement in our daily life.

Centimeter, Meter and Kilometer

When comparing the three units centimeter is the smallest unit and kilometer is the largest.

1 meter= 100 cm

1 kilometer= 1000 meter= 100000 centimeter

If we measure the height of the classroom's door  in centimeter which is approximately 223 cm, it is better to convert it into a unit higher than centimeter. We know that 100 cm is equal to 1 meter. So, instead of writing 223 cm it is better to write 2.23 m, neither 0.223 Km.  If the number lies between 100 cm ≤number <100,000 cm,  convert it into meters by dividing the number by 100, which is best unit of measurement.
