Which instrument allows for the most precise measurement of mass? (The measurements are shown for each device.)

Isee the amount was $90.00 then reduced to $75.00 , what is the percent ?

Type the correct answer in the box. consider the system of linear equations below. rewrite one of the two equations above in the form ax + by = c, where a, b, and c are constants, so that the sum of the new equation and the unchanged equation from the original system results in an equation in one variable.

If a and −a are numbers on the number line, which expression must give the distance between them? a) 0 b) a c) |2a| d) |a|
