Solve the system of equations 3r -4s equals 0 and 2r plus 5s equals 23?

Presumably this is a simultaneous equation in the form of: 3r-4s = 0 2r+5s = 23 Multiply all the terms in the top equation by 2 and in the bottom equation by 3: 6r-8s = 0 6r+15s = 69 Subtract the bottom equation from the top equation: -23s = -69 Divide both sides by -23 to find the value of s remembering that a minus number divided into a minus number is equal to a plus number: s = 3 Substitute the value of s into the original equations to find the value of r: Therefore: r = 4 and s = 3


If a circle with a diagonal line through it is a symbol for no solution how you designate the case when any value satisfies the equation?

When any value satisfies the equation, you would simply state "all real numbers." There is a symbol for it, and even though it is difficult to explain, I will attempt to. It is simply an R with an extra line making it kind of look like |R, but it's connected to the furthermost left parallel line. I hope that helps!


What is the radius if area equals 289 pi?

Recall the equation A = pi * r^2. You've given the information that A = 289 pi. Now, simply solve the equation for r: A = pi * r^2 289 pi = pi * r^2 289 = r^2 sqrt(289) = r 17 = r


How do you solve for the Radius r in the cylinder equation V equals rh?

If v = r * h then> r = v / h


Rex is 30 years younger than his father his mother is three times as old as her son find rex's age if his father is two years older than his mother?

Lets call them R for Rex, F for Father and M for Morther F - 30 = R M = 3R F - 2 = M If we subtract the third equation from the first one we get F - 30 = R F - 2 = M ------------ 0 - 28 = R - M or M - R = 28 Now, if M = 3R we can substitute that into the above and we ger 3R - R = 28 2R = 28 R = 14 So, if Rex is 14, his mother is 3 x 14 = 42 and his father is 14 + 30 = 44 - which is 42 + 2.
