There are several options.
3*(2 + 7 - 1!) + √99! * 0 = 24
0.5
The 'answer' is the number that 'c' must be, if 5c is really the same as -75.In order to find out what number that is, you could use 'algebra'.First, write the equation, so that you can look at it:5c = -75Now, use the law of algebra that says: "If equals are divided by equals,then the quotients are equal".The left and right sides of your equation are equals. Divide them both by 5,and that law says that the quotients on both sides will be equal:c = -15
"3x + 2y - x + 2y" is an expression that is often part of an equation; possibly a linear equation, though it could be of higher order as there could be squares, cubes etc. To be definite there would be an equals sign (=) and an expression, usually a number, the other side of it.
a linear first-order differential equation is homogenous if its right hand side is zero & A linear first-order differential equation is non-homogenous if its right hand side is non-zero.
-- 4 numbers can be lined up in 24 different ways-- If the order doesn't matter, then there's only one4-number combination of 4 numbers.
x = 4 and y = 7
Well, that's pretty complicated, and we're a little rusty,but we'll give it a try.The "answer" is the number that 'n' has to be in order to make it true.2n - 5 = 7Add 5 to each side of the equation:2n = 12Divide each side by 2:n = 6
This equation is unsolvable since there are two unknowns and only one equation. You would require a second equation in order to solve it.
x = 4 and y = 7 which will satisfy both equations
It means to find what numbers the variables (the letters) must be in order to make the equation a true statement.
You would need to know what a is equal to in order to calculate this equation.
Multiply by 4
In order to answer that, we need an "equation" that shows us the relationship among 'Y', 'A', and 'B'.
It means to find what numbers the variables (the letters) must be in order to make the equation a true statement.
There are three variables in the equation. In order to find numbers for all of them,you need three separate independent equations.As it is now, the graph of that equation is a line in 3-dimensional space, andevery point on the line is a 'solution' to the equation. We don't have to tell youhow many points there are on a line, do we ?
It works out that: x = 3 and y = 2
The product is the answer to a multiplication equation.
