Which best describes how to solve the equation 64x equals 37?
Divide both sides by 64 to find the value of x
The line of best fit has the equation equals -1.5 plus 2.5x What does this equation predict for a value of x equals 3?
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
Which is the best way to solve the equation x2 n?
do you mean, x2 = n?? Take the square root.
To solve the system given below using substitution it is best to start by solving the second equation for y?
True
If you were to solve the following system by substitution what would be the best variable to solve for and from what equation 2x plus 6y equals 9 3x-12y equals 15?
2x + 6y = 93x - 12y = 15Chose the second equation because you can simplify it.3x - 12y = 15 divide by 3 to both sidesx - 4y = 5 add 4y to both sidesx = 4y + 5Replace 4y + 5 for x to the first equation.2x + 6y = 92(4y + 5) + 6y = 98y + 10 + 6y = 914y = -1y = -1/14x = 4y + 5x = 4(-1/14) + 5x = -2/7 + 5x = -2/7 + 35/7x = 33/7
Which is the best way to solve the equation the square root of x equals m?
It depends on which variable you wish to solve for.
Which is the best way to solve the equation x2 equals n?
Take the square root of both sides of the equation
Which best describes how to solve the equation 64x equals 37?
Divide both sides by 64 to find the value of x
How do you solve this equation for x y equals x minus x squared?
It is not possible, in general to solve one equation in two unknown variables. The best that you can do is rewrite the eqaution so that one variable is defined in terms of the other. xy = x - x2 = x(1 - x) Assuming x not 0 (else the original equation degerates to 0 = 0) we can divide both sides by x to give: y = 1 - x
What is the best what to solve the equation 64x equals 37?
64x = 37 Divide both sides by 64: x = 37/64 or 0.578125
Which is the best way to solve equation x equals k?
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!
Which is the best way to solve the equation x2 equals k?
X2 = k Take square root each side. X = (+/-) sqrt(k) ============
What is the answer to c equals 10n-5?
15
If you are asked to solve a system of equations in which there is no linear equation to start with you can sometimes begin by isolating and substituting a variable that is squared in both equations?
true
Area an radius equals 42 square feet What is the best translation of this equation?
Which of the following is the best translation of this equation?
The line of best fit has the equation equals -1.5 plus 2.5x What does this equation predict for a value of x equals 3?
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
How do you solve b2 plus 4b plus 4 equals 15?
The best plan for that particular equation would be to first subtract 15 from each side, and then apply the quadratic formula.
