Answer:
10 years.
Step-by-step explanation:
Let Jerome, Keenan, and Leitha have ages of x,y and z respectively,.
Then given that x+y =18 ... i
x+z =19 ... ii
y+z = 21 ... iii
From the above information we are to find out y and i.e.Keenan age.
Add all the 3 equations
Left side becomes x+y+y+z+z+x = 2(x+y+z)
and right side becomes = 18+19+21 = 58
In other words, 2(x+y+z) = 58
Divide by 2
x+y+z =29 ... iv
From the equation iv subtract ii
x+z =19
We get y = 10
Hence Kennan age = 10 years
Answer: I believe the scale is balanced.
Step-by-step explanation: I stated that because since the other side of the scale contained 12 marbles that were 1 pound each that would be 12 pounds and then since 4+8=12 12 pounds of marbles were also put on the other side.
Answer: -0.33
Step-by-step explanation:
So how you would do this as you would set it up in a graph on a piece of paper you would take both points you'd use your slope formula, which is m=y2-y1 over x2-x1 And then you sell your formula with the numbers. So it would be 3-5 over 5-(-1) And then you subtract both of those and you take your two answers and divide them. -2÷ 6 =
