Question

Use unit analysis to determine the unit of measurement for the expression 10x + 25y​

Answer 1

Answer:

Given 10x + 10y

It has to be ensured that x, and y are a part of the same unit system, like if y is meter, then x can be kilometer, centimeter, or milimeter. And we will multiple and divide the bigger or smaller out of the above to get them to the unit, we want them to be in. Like if y is in meter, and x is given in centimeter then, we should divide x by 100 to convert it to meter, and then we can add both.

like

  x=3 centimeter, and y= 2 meters

x = .03 meters

  hence = 0.03 *10 + 10*2 =20.3 meters
