Scientists use the metric system when gathering data and performing experiments. which of the following statements about the metric system
are true? select three correct answers
a scientists need a common system of measurement in order to gather qualitative data
b. the units of the metric system are scaled on multiples of 10, making mathematical calculations easier to perform
c. the units of the metric system include kilograms for mass, meters for length, liters for volume, and degrees celsius for temperature
d. scientists often retest others' experiments, so a common system of measurement is essential.

The correct answer will be options- A, B and D.

Explanation:

The metric system is an internationally accepted decimal system of the measurement which was adopted in France in 1795. This system is now widely accepted and used system in the world.

The metric units are based on the division and multiplication by an integer of ten thus, units can be scaled on the 10 which makes the calculation easy.

The metric system was accepted as the international system of units in 1875 when the International Bureau of Weights and Measures was established. The motto of this system was that it could be followed by all people all the time.

Thus, the selected options are the correct answers.

Here, we are required to select 3 statements which are true about the metric system.

The correct answers are options A, B and D.

The metric system refers to a system of measurements of length, capacity(volume), mass by using meter, liter and gram as base units respectively.

However, it is possible to measure smaller or higher units by adding prefixes to the base units. Such prefixes may correspond to higher units (i.e Deca-, Hecto-, Kilo- and so on) or lower units (deci-, centi-, milli-).

Therefore options A, B and D are correct as follows:

try using substitution:

x + y - 6 = x - y. (i'm not giving you the exact answer). since 0 = x - y, then sub 0 in the equation with x - y. combine your like terms, and then use inverse operations, and you'll have your answer.
