Answer:
x=-7, y= -20
Step-by-step explanation:
2x - y =6
x - y = 13
when I subract (x-y =13 ) from (2x-y =6)
2x -y =6
-x +y=-13
______________
x = -7
substitute x=-7 in the second equation
-7 - y =13
-y = 13 +7
-Y = 20
Y=-20
x=-7, y= -20
Answer:
Ok so...
Mean: 68.76
Median: 72
Range: 85
Step-by-step explanation:
You need PEMDAS
do 3·6 and then 12/6
when you subtract the product and quoetient you get 16 for the answer
C. 7. because if you divide the value for the missing term (take 28 for example) and divided it by the value of i (4) you will get 7. (28÷4=7)
there is a 50% chance of landing on either heads or tails
