Answer: Michael is 72 while Ann is 36.

Step-by-step explanation: Let X represent Michael's age and Y represent Ann's. From the first sentence,

Y=2X. (eqn 1)

14+X=Y-22 (eqn 2)

X-Y=-22-14

X-Y=-36; But Y=2X.

Therefore, X-2X=-36; -X=-36; X=36. Hence, Y=2*36; Y=72.

-3x - 3y = 3 <br> y= -5x - 17
Kruka [31]

you first plug (substitute) in y

-3x - 3(-5x-17)=3

then distribute

-3x+15x+51=3

now combine like terms

12x+51=3

subtract to get 12x by itself

12x=3-51 or 12x=-48

lastly divide by 12 to find x

12x/12=-48/12

x=-4

now find y by plugging x into the other equation

y=-5(-4)-17

y=3

(-4,3)

The correct option is;

3 + (-9) = -6, because -6 is 9 units to the left of 3

The given information are;

Kelvin's score after the first round is shown at point K on the number line

The range of numbers on the number line = -10 to +10

The position of point K after the first round = +3

The number of points Kevin lost in the second round = 9 points

Therefore, Kevin's cumulative score = +3 - 9 = -6

Therefore, the expression that shows how many total points he has at the end is of round 2 = 3 + (-9) = -6, because -6 is 9 units to the left of 3.
