It depends on which variable you wish to solve for.
The best way to solve questions like this is division. For a question "How many (a) are in (b)?" we'd do b divided by a, so in this case, 30,000 / 10, which equals 3,000, so there are 3,000 tens in 30,000
The answer is .90. Simply add the numbers together arithmetically as you would for the problem two plus two. To check your work, a calculator is the best option.
To find the square root of a number, take that number to the one-half power. Ex: 4^1/2 = 2 The best way to find a square root is simple guess and check. Because not all square roots are whole numbers, it is advisable to use either a calculator or square root table to find more complicated square roots.

The wave equation
If u want to solve a problem so u wait for it. Do not answer anything before u think it
Take the square root of both sides of the equation
X2 = k Take square root each side. X = (+/-) sqrt(k) ============
Which of the following is the best translation of this equation?
If x squared equals n, then x is the square root of n.
Without an equality sign the given expression can't be considered to be an equation.
do you mean, x2 = n?? Take the square root.
Divide both sides by 64 to find the value of x
64x = 37 Divide both sides by 64: x = 37/64 or 0.578125
You cannot go beyond x = k unless you know the value of k. And in that case, the equation is solved so there is nothing further to do!
15
6The line of best fit has the equation = -3 + 2.5x. What does this equation predict for a value of x = 3?Answer: 4.5
The best plan for that particular equation would be to first subtract 15 from each side, and then apply the quadratic formula.
