Vikentia [17]
Metric system is standard or measurement developed in 1670's by Gabriel Mouton. This is a decimal system of measurement for length, mass and volume. The SI unit of length is meters. In the metric system, the spectrum for the units of length is

km   hm   dkm   m   dm   cm   mm

The greatest starts from the left side" kilometer(km), hectometer(hm), decameter (dkm), meter (m), decimeter (dm), centimeter (cm) and millimeter (mm). The same prefixes are applied to units of mass in grams and volume in liters, like milligrams and milliliters. To use the metric system, place 77 mm above the mm scale. To convert it to m, you have to move the decimal place 3 places to the left. Use the scale to guide you. Hence, 77 millimeters is equal to 0.077 meters.

Markus scared 85, 92, 82, and 94 on the first four tests of the semester. His teacher has not yet told him his score on his fift
alexandr1967 [171]

Answer:

y — x = 5

5y — x = 353

Step-by-step explanation:

Let the fifth score be x

Let the average of all the scores be y.

But the fifth score is 5 points lower than the average ie

y — x = 5 (1)

The average of the scores is the sum of all the scores divided the number of scores. This is written as

y = (85 + 92 + 82 + 94 + x) /5

y = (353 + x) /5

Multiply through by 5

5y = 353 + x

Rearrange the equation

5y — x = 353 (2)

The equation Markus will use to determine the x is given as

y — x = 5

5y — x = 353
