Let X be the larger number and Y be the smaller number. So, X + Y = 2X - 4 and X - 3Y = -20 (1) Rearrange the first equation to get the variables to one side: X - 2X + Y = -4 -X + Y = -4 (2) Next solve simultaneously with the other equation. Add equations together to eliminate X. -X + Y = -4 X - 3Y = -20 ------------------- -2Y = -24 Y = 12, and substituting this value into the first equation and solve for X to get X = 16
The larger of two numbers is 8 more than 4 times the smaller if the larger number is increased by four times the smaller the result is 40. From this statement, we can calculate the values of the numbers where you get the value of the larger number to be 24 and that of the smaller number to be 4.
A number.We can't be more specific because we don't know if the second number is larger, smaller, or the same as the first. If it's larger, the result will be negative; if it's smaller, the result will be positive; if they're the same, the result will be zero.
When 40 is decreased by 30% the result is 28.
When 180 is decreased by 40% the result is 108.
When 3 times a number is decreased by 4 the result is 17. what is the number?

First of all you need serious help with your grammar, more than your math. I will try to make sense of what you wrote. 24 and 4 are the numbers you are looking for.
Yes
Pressure is defined as force divided by area. If you divide by a smaller number, you get a larger result. Try it out with some numbers.
One option for comparing two numbers is to subtract the first number from the second number. If the result is less than zero, the first number is larger. If the result is greater than zero, the second number is larger. If the result is zero, the numbers are equal. Another option (for positive numbers) would be to divide the first number by the second number. If the result is greater than one, the first number is larger. If the result is less than one, the second number is larger. If the result is one, the numbers are equal. This rule flips if you are comparing negative numbers.
They add together. *Note: when dealing with vector forces, adding them together could result in larger, smaller or even negative numbers, based upon the signs' of the original numbers

Divide the larger number by the smaller. If the result has no remainder (no decimal) then the smaller number is a factor of the larger.
The smaller number is a factor of the larger number, and the larger number is a multiple of the smaller.

Try it with easier numbers. 12 divided by 4 = 3, 12 divided by 3 = 4 Dividing by a larger number gives a smaller result.
