The absolute value of a number describes its magnitude, or the distance a number is from zero when
placed on a number line
so |-2| = 2
Alright, so if we wanted to take, for example, cell phone owners per 100 people and compare Germany to the USA, we can start by making up a number for Germany - 80 - and a number for the USA - 70. Next, the ratio of people using cell phones is 80/70=8/7 with the numerator being the people from Germany and the denominator being the number from the USA.
Angle M corresponds to angle N
As there are no given data to work with in this given problem, allow me to generally describe the steps involved in going about this type of problems.
If we are asked about rate, we simply divide the number of fuels (in gallons) used by the racing dragster by the time (in second) it takes for it to be consumed.
The numbers will be X and Y with X being the lesser
x+y=45
2y=5x+6
now use a subtraction method to solve
x+y=45
y=45-x
2 (45-x)=5x+6
90-2x=5x+6
-7×=-84
x=12
y=45-12
y=33
so, x=12 and y=33
