Just substitute their values into the expression:
= -8 + 9 + 5z + 7x
= -8 + 9 + 5(3) + 7(5)
= 1 + 15 + 35
= 51
In short, Your Answer would be 51
Hope this helps!
11a) False. If you simplify 8/30 you get 4/15 not 2/15.
11b) False. If you simplify 6/15, you get 2/5 not 3/5.
11c) true. 5/15 can be simplified to 1/3.
-- 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.
The $4 for 5 ounces because think about how much 1 ounce would be so that's how you would get your answer it tells you which on is the lowest
3n-5=-48-40n
Move -40n to the other side. Sign changes from -40n to +40n.
3n+40n-5=-48= -48-40n+40n
3n+40n-5=-48
Move -5 to the other side.
3n+40n-5+5=-48+5
3n+40n=-43
43n=-43
Divide by 43 for both sides
43n/43=-43/43
n=-1
Answer: n=-1
