Which two numbers have the mean of 10 and the range of 8?
6 and 14 Solution x - y= 8, so x =8 + y, (x + y)/2 = 10, x + y = 20, Substituting x = 8 + y, we have: 2 y + 8 = 20, or 2y = 12, y = 6, x = 6+8= 14
What is the smallest number with both 8 and 12 as factors?
Prime factors of 8 are 2 x 2 x 2 Prime factors of 12 are 2 x 2 x 3 LCM of 8 and 12 is 2 x 2 x 2 x 3 = 24
What is 6 times 10 to the 12 power in parenthesis to the second power?
(6 x 10^12)^2 = 6^2 x (10^12)^2 = 36 x 10^24 = 3.6 x 10^25.
What is half the product of 8 and 12?
8 x 12 = 96 96 / 2 = 48 Half the product of 8 and 12 is 48.
How many ways can you choose 5 from 12?

If 2 3rds times X plus 2 equals 10 what is X?
x=12 . . . as two thirds of 12=8 therefore 8+2=10
What is the distributive property of multiplication for 12 x 8?
8 x 12 = (8 x 10) + (8 x 2) = 80 + 16 = 96
How do you solve x over 2 plus 4 equals 10?
I assume you mean, ( parentheses!!!) X/2 + 4 = 10 multiply through by 2 2/1(X/2 + 4 = 10)2/1 X + 8 = 20 subtract 8 from each side X + 8 - 8 = 20 - 8 X = 12 ------------------check in original equation 12/2 + 4 = 10 6 + 4 = 10 10 = 10 ----------- checks
What is 2 to the third power equals 8 10 or 12?
8 = 2 x 2 x 2 = 2³
How do is 2x plus 8 equals x plus 10?
To solve the equation 2X+8=X+10 the first step is to get all instances of the variable 'X' on the same side of the 'equals' sign. To do this, we must first subtract 'X' from both sides of the equation: 2X+8-X=X+10-X which then becomes X+8=10. The next step is to leave the variable 'X' alone on it's side of the 'equals' by subtracting the numeral 8 from both sides of the equation: X+8-8=10-8 which then becomes X=2. To confirm that the solution is correct, we then substitute the solution we arrived at into the original equation in place of the variable 'X': 2*2+8=2+10 2*2=4 so: 4+8=2+10 4+8=12 and 2+10=12 so the final solution is: 12=12 Therefore the answer to the question "Is 2X+8 equal to X+10" is Yes, and the value of the variable 'X' is 2

4x-8 equals 12 plus 6x?
4x - 8 = 12 + 6x 4x - 6x = 12 + 8 -2x = 20 -x = 20/2 x = -10 Check: 4(-10) - 8 = 12 + 6(-10) -40 - 8 = 12 + -60 -48 = -48
