We see that both equations have 4y in them. Subtracting the second equation from the first equation, we get (3x -2x) + (4y-4y) = 2 - 8, x = -6
Plugging x = -6 into any equation, we see that our answer is 18 + 4y = 2, 4y = 2 - 18 = -16, y = -4.
Our answer is x = -6, y = -4
Henry will be 37 next year. If Riley is half as old as Henry then you would divide 72 by 2. That gives you 36 which is how old they both are. Next year Henry will be 37. ( Riley would be too but it doesn't ask for her)
Answer:
13.59
Step-by-step explanation:
The calculation of amount of cash in the room is shown below:-

= 20 × $14.50
= $290
Now, the new sum is
= ∑xi + $4.00 + $5.00
= $290 + $4.00 + $5.00
= $299
Total person in the room is
= 20 + 2
= 22
So,
Mean amount of cash in the room = New sum ÷ Total person in the room
= $299 ÷ 22
= 13.59
The value of the X must be 74 in. ..
I believe the answer is 1792.
