Answer:
X=6
Y= - 1
Step-by-step explanation:
X-y =7
X+y =5 cross - y and y
_______
X+x =7 +5
2x= 12
X= 12/2
X= 6
Replace X in first equation:
X - y =7
6 - y =7
6 - 7 =y
y = - 1
Hope this helps you.. Good Luck!

Answer:
1/480
Step-by-step explanation:
<h3>for the 6 sided one</h3>
rolling a 5 is 1/6
<h3>for the 8 sided one</h3>
rolling a 5 is 1/8
<h3>for the 10 sided one</h3>
rolling a 5 is 1/10
total probability= 1/6*1/8*1/10
= 1/480
Answer:
x = 14
JHK = 21
Step-by-step explanation:
The angles are vertical angles and vertical angles are equal
3x-21 = x+7
Subtract x from each side
3x-x -21 = x+7-x
2x-21 = 7
Add 21 to each side
2x-21+21 = 7+21
2x = 28
Divide by 2
2x/2 =28/2
x = 14
JHK = 3x-21 = 3(14) -21 = 42-21 = 21
