Find the number in the tenth place 0 and look one place to the right for the rounding digit 9. Round up if this number is greater than or equal to 5 and round down if it is less than 5.
Answer: 0.1
Fred's age is 13 years
Let
Fred's age = x
Jack's age = 2x + 4
After 8 years:
- Fred's age = x + 8
- Jack's age = 2x + 4 + 8
= 2x + 12
Sum of their ages = Fred's age + Jack's age
59 = (x + 8) + (2x + 12)
59 = x + 8 + 2x + 12
59 = 3x + 20
59 - 20 = 3x
39 = 3x
x = 39/3
x = 13 years
Therefore, Fred's age = 13 years

Seven is the highest and john is the lowest so seven(18)- john(8)= 10 is your answer
Eliminate one variable at a time. We have three equations so we can solve for three variables.
(5x-y+z=4)-5(x+2y-z=5)=-11y+6z=-21
-2(x+2y-z=5)+(2x+3y-3z=5)=-y-z=-5
Now using the two yz equations above to cancel out z
(-11y+6z=-21)+6(-y-z=-5)=-17y=-51
-17y=-51 divide both sides by -17
y=3, making -y-z=-5 become:
-3-z=-5, z=2, making <span>5x-y+z=4 become:
5x-3+2=4
5x-1=4
5x=5
x=1
So the solution to the system of equations, (x,y,z) is (1,3,2)</span>
