How do you solve the expression 2500x equals 5 please help?
Use the commutative rule in math. If you do something to one side of the equation, you must do the same to the other side. Divide both sides by 2500 to get x = 5/2500, reduce the fraction to get the answer.
How do you solve this equation x over 9 equals 12?
x/9=12 multiply both sides by 9, giving x=108 ____________________________________________________________________ To solve the problem 'x over nine equals twelve', you must first recognize that any number over another number (which includes variables) is a division problem. Thus, all fractions are division problems. You have to multiply by the reciprocal, and multiplication is the opposite of division, and the reciprocal in this case would be 9/1, or just 9. You must apply this to both sides of the equation, so x/9 times 9 is x, and 12 times 9 is 108. Therefore, x =108.
How do you solve an inequality with fractions and variables on both sides?
You solve an inequality the same way you solve an equality. You add and subtract, multiply and divide, both sides by the same value in order to isolate one of the variables. The only extra thing you need to remember is that if you multiply or divide by a negative number, you must reverse the order of the inequality, i.e. less than or equal becomes greater than or equal.
-5b - 12 -2 what is b?
To solve for b, you must form an equation (-5b -12 -2 = 0). Next you must separate the known numbers from the unknown by adding the sum of the knowns to both sides of the equation (-5b = 14). Then divide both sides of the equation by -5 to find the value of b (b = -2.8).
How must is x plus 3 equals -12?
-9
What operation must be done to both sides of the equation to solve p plus negative three and seven-ninths equals five-sixths?
yes
To solve 5x 65 you must both sides by 5?
divide
How do you solve 5-4mdivided by 3 equals -7?
To solve for m, we must isolate m: (5-4m)/3 = -7 Multiply both sides by 3: 5-4m = -21 Subtract 5 from both sides: -4m = -26 Divide by -4: m = 13/2 = 6.5
What is 2 step equation that equals 9?
There are infinite possibilities. but a simple one is 5x - 6 = 9 To solve this, you must isolate x. first add 6 to both sides, and then divide 5 from both sides. This will leave you with x = 3.
How would you solve this equation 235 equals x - 84?
151
How do you solve 10x plus 3 equals 15?
In this case, we are solving backwards to find the value of 3. We must reverse the order of operations to solve for x since we are working backwards. subtract 3 from both sides of the equation. this will leave us with 10x = 12. Then, we can divide both sides by 10, and we will be left with 12/10. The main goal of solving for x is to isolate x. We want x to be on one side of the equation all by itself. Think of equations like a balance bean. If we take 3 away from both sides, the balance will still weigh the same on both sides. Then, if we divide 10 by both sides, the balance will still weigh the same on both sides again because its done to both sides of the equation. Aside from when you are simplifying one side of the equation for simplicity, what you do to one side of the equation you must do to the other.
5x plus 8 equals 16-3x?
5x + 8 = -3x + 16 add 3x to both sides, this gives you... 8x + 8 = 16 minus 8 from both sides, this gives you... 8x = 8 divide by 8 to get what x equals (must divide both sides), this gives you... x = 1
Solve 7x 6y equals 126?
Not sure if you mean 7x 6y as in 7*6y=126, where * means "multiplied by" and you must solve for y or if you mean that we must solve for both x and y, but the answer to the part where you are solving 7*6y=126 is 3.
How can you use prevention to solve conflict?
Communication and compromise are two things that can be used to prevent conflicts. They can also be used to help solve conflicts. Both sides must be willing to participate.
How do you solve the expression 2500x equals 5 please help?
Use the commutative rule in math. If you do something to one side of the equation, you must do the same to the other side. Divide both sides by 2500 to get x = 5/2500, reduce the fraction to get the answer.
3x plus 8 equals -7 find x with work?
3x + 8 = -7 Subtract '8' from both sides 3x - 9 + 8 = -8 -7 3x = -15 Divide both sides by '3' 3x/3 = -15/3 x = -5 The answer. NB 'When saying/writing ' both sides' , remember the 'equals' sign . You MUST keep the equation 'equal/ balanced' like a pair of weigh scales. So whatever you do to one side , in the way of '+, -, x, /.' you MUST do to the other
37.5 percent of what number is 8.13?
In math "of" means multiplication(*), "is" means equals(=), and "what number" can be described as a variable such as "X". Also 37.5 percent written as a decimal is .375 thus you can write this equation as: .375*X=8.13 --> then you must solve for X to find the number. To solve for X you must divide both sides by .375. Thus your answer comes out to be (8.13/.375) which is equal to 21.68
