x-y=16
x=4y-5
x-y=16
x-4y=-5
(x-y=16)-1
-x+y=-16
x-4y=-5
(you're gonna add these together)
-3y+-21
y=7
then plug it into the equation: x-y=16
x-1(7)=16
x-7=16
x=23
so your numbers are (23,7)
On a number line, the numbers start with zero and get larger as they move to the right, They are negative and get smaller as they move to the left from the zero. To find which number is greater, you can find the places of two numbers on the line and the one on the right is greater.
You can do this by inspection. If the second number is smaller than the first, their difference is positive. If the second number is greater than the first, then their difference is negative. If the second number is the same as the first number, then their difference is zero.
Any three numbers where the sum of the two smaller numbers is greater than the third number. List the numbers in order from least to greatest, repeating any number if necessary. Add the first two numbers together and if this sum is greater than the third number then a triangle with those sides can be made. ie if the sum of the two smaller numbers is greater than the third number then a triangle can be made.
In a set of numbers, the difference between the greatest and the least is called the range.

There are two consecutive odd numbers such that five times the smaller plus twice the greater is 25. What is the smaller number?

The difference of two numbers is equal to the smaller number taken away from the greater number. Now let's take a look at our problem. The greater number is 2.5 and the smaller number is obviously 1.44. So now, take 1.44 away from 2.5. Line up the decimal places and add necessary zeros in the empty spaces. The answer is 1.06.
The mass number is the sum of protons and neutrons.
No. Consider 0 and 1. Or negative numbers, whose sum produces a smaller number.

None. If a number is smaller than 36 it cannot be greater than 89.
Any three numbers where the sum of the two smaller numbers is greater than the third number. List the numbers in order from least to greatest, repeating any number if necessary. Add the first two numbers together and if this sum is greater than the third number then a triangle with those sides can be made. ie if the sum of the two smaller numbers is greater than the third number then a triangle can be made.

52 and 156.
The number with the smaller absolute value (magnitude) is greater.
