Answer:
10/7
Step-by-step explanation:
divide both numbers by 5
<span>3d - 6 = 5 --> add 6 to each side
3d = 11 --> divide by three on each side
</span>D = 3.66666666
-- The average of 6 numbers is 7.
So those 6 numbers must add up to 42.
-- If one more number results in an average of zero,
the new number must be -42 .
Then all 7 numbers add up to zero.
Answer:
11-2x=x+2
-3x=9
x=-3
Step-by-step explanation:
y=11-2x
y=x+2
So we use the first equation to plug in for the second equation.
Then we solve for x and get the answer. Hope this helps. Thank you.
