Answer:2, -2
Step-by-step explanation:
X=9 -12 divided by -4 is -3, so you get -3x=-27. When you divide -27 by -3 you get positive 9. Thus making X=9
Expression: 2n - 1
When n = 7
2n - 1 = 2(7) = 1 = 14 - 1 = 13
Answer:
11 lollipops
18 candy bars.
Step-by-step explanation:
Let the number of lollipops sold be x and the number of candy bars sold be y. Then:
x + 1.25y = 33.50
y = x + 7
-x + y = 7 Adding this to the first equation:
2.25y = 40.50
y = 18
so x = 18-7 = 11.
The answer to this is 9 , so t is C , to work this out you would divide 18 by 2 to give you 9 <span />
