- Combine like terms, 2x2+6xy
You multiply two rational numbers by multiplying numerators and denominators with each other. So, you have

A rational number is a fraction where both numerator and denominator are integers. Since the product of two integers is an integer, the result fraction is also a rational number, because both
and
are integers.
Step-by-step explanation:
The solution to this problem requires that we find other units besides the given one
1. ft/sec
2. km/h
3.m/s
1. converting to ft/sec
1 mile is 5280 ft

2. converting to km/h
1 mile is 1.60934

3. converting to m/s
1 mile is 1609.34

20x-28+12=16x+24 (i distributed the 4 to get this)
20x-16=16x+24 (added -28 & 12)
4x=40 (Subtracted 16x from both sides and added 16 to both sides)
(divide by 4 on both sides)
x=10
