What operation would isolate the variable in this equation -g equals 35?
-g is really -1g so divide -1g by -1. what you do to 1 side, you have to do to the other side. so divide 35 by -1. the solution is g= -35
How do you solve 5t equals 25?
In the equation 5t = 25, t is simply a variable that you are solving for. You can replace "t" with a variable you are more comfortable with, such as "x", leaving you with 5x = 25. The equation means: 5 times what equals 25? To get this, you would divide both sides of the equation by 5, leaving it as (5t)/5 = 25/5. The 5 on in the denominator and numerator on the left side of the equation would cancel out, leaving you with t = 25/5, which you can simplify to t = 5.
What is x minus 3?
X is a variable term, in simpler terms, means that it's always something different. X is given in certain problems to be figured out. In the equation: x-1=5 x would answer 6. Or x+3=10 x would have to equal 7. Its ever-changing.
How do you graph the equation x plus 3 equals 0?
Move 3 over the right side of the equation so the equation would be x = -3. The graph of this would be a verticle line at x= -3
2x plus 3y equal 40 -2x plus 2y equal 20?
2x+3y=40-2x+2y=20Since 2x does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting 2x from both sides.3y=-2xDivide each term in the equation by 3.(3y)/(3)=-(2x)/(3)Simplify the left-hand side of the equation by canceling the common terms.y=-(2x)/(3)if you were solving for x It would be x=-(3y)/2
Which operation would isolate the variable in this equation 51q equals 1020?
divide by 51
What do you use to isolate a variable in an equation?
You would use inverse operations. I had this on my math homework and got it correct so I know this! ============================================== Good for you ! You know what you said, but you don't know what you know. I'd say that you use the Golden Law: "You must always do exactly the same thing to both sides of an equation."
Which property of equality would be used to isolate the variable a in this equation?
That depends entirely on the equation which has not been given but in general whatever is done on one side of an equation must be repeated on the other side in order to keep the equation in 'balance'
How the order of operations determines how you evaluate an algebraic expression?
Well, if I understand what you're asking, the order of operations is simple and helpful. For example, if you have this equation (with "a" being the variable): 3a - 4 * (18-14) = 20 then you first do parentheses (P in PEMDAS). So, the answer to 18-14 would be 4. Then, since there are no exponents (E), you multiply (M) 4 * 4, which equals 16. Next, since the remaining part of the equation is 3a - 16 = 20, you add (A) 16 to the other side to balance out the equation. Now, all is left is 3a = 36. Now, you just divide (the remaining part of the equation does NOT follow the rule. It goes out of order for some reason). The answer to a is 12. The equation does follow the rules of the order of operations. At the point 3a-16=20, you cannot combine any more terms in the order of addition or subtraction because their aren't any like terms to combine. In algebra, you are solving for the unknown variable, in this case (a). In order to solve for (a), you have to isolate the variable. You do this by balancing out the equation and adding 16 to both sides of the equation, therefore being left with 3a=36. Then you divide by three to further isolate the variable. When left with unlike terms, in essence, you do the order of operations in reverse.
What is 336 divided by x equals B?
The idea is to "isolate" the variable, in this case "x", on one side. In this case, you would start by multiplying both sides of the equation by "x".
Which property would be use to isolate the variable j in this equation 7j equals 49?
You would use several properties. The first is that performing the same operation to both sides of an equation is valid. Next the multiplicative inverse property of 1/7 (with respect to 7).
Which would be the independent variable and which would be the dependent variable?
A dependent variable is usually on the side of the equation by itself. The independent variable usually has something being done to it. And, the dependent variable is usually written to the left of the equation.
-10 x plus 12?
If you are trying to solve the equation -10x plus 12 equals zero the equation would look like this: -10x+12=0. You would begin by subtracting 12 from both sides of the equation to isolate the variable x on one side leaving you with: -10x=-12. Next you would divide both sides of the equation by -10 resulting in: x = 1 and 1/5.
What operation would isolate the variable in this equation -g equals 35?
-g is really -1g so divide -1g by -1. what you do to 1 side, you have to do to the other side. so divide 35 by -1. the solution is g= -35
How would you solve x-1 equals 4?
By adding one to each side of the equation. The general approach to this kind of problems is to "isolate" the variable (in this case, "x") on one side of the equation, getting rid of anything else. However, you must always do the same thing on both sides of the equation, otherwise, you will get wrong results.
How would you get the variable alone in the equation 4y3?
As it appears, there is no equation but an algebraic term.
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.
