What is the solution of the equation x-12-25?
Without an equality sign the given expression can't be classed as an equation but it can be simplified to: x-37
What is the equation of direct variation if y is 16 when x is 20?
The equation can be written as y = 16x/20 which can be simplified to y = 4x/5
Explain the difference between the directions solve evaluate and simplify?
To solve would be to rewrite the equation in terms of the variable in the equation. For example, solve: 3x-2=7. You would solve for the variable x; e.g. 3x=9 and x=3. To evaluate, you would be given an equation with a variable or variables. You would need to be given a value for the variable(s) to substitute into the equation. For example evaluate the equation for x=3; equation is x2+1. Substitute 3 in for x; or 32+1=10. To simplify, reduce the equation to its simplest form. This will involve operations such as: factoring, adding, subtracting, dividing, canceling terms, and so forth. For example simplify the equation: 3x3/9x2. The 3/9 is simplified to 1/3 and x3/x2 is simplified to x. So the original equation simplified is: 1/3 times x or (1/3)x or x/3.Which is the right answer for most of you who does not know.
How do write 0.72 repeating as a fraction?
You need to call your number "x", then write the following two equations:(Equation 1) x = 0.727272... Multiplying by 100, you get: (Equation 2) 100x = 72.727272... If you subtract equation 1 from equation 2, and solve for "x", you will get the number as a fraction.
What is a simplified polynomial?
a simplified polynomial is a algebraic equation/expression with variables and constants that can can be written as a sum of terms. Simplified form is the opposite of factored form P(x) = ( 2x - 3)( x+4 ) Is a factored form - product of 2 factors. Simplify P(x) by using the distributive property: P(x) = 2x2 +8x - 3x -12 P(x) = 2x2 + 5x - 12 simplified : a sum of terms!
