8*(n+6)=80
distribute
8n+48 = 80
subtract 48 from each side
8n = 32
divide by 8
n=4
the missing number is 4.
8*(x+6)=80
divide both sides by 8
x+6=10
subtract 6 from both sides
x=4.
hope i was able to help. god bless. :D
Answer:
Step-by-step explanation:
For every 10 assignments you get 1 homework pass. So you would multiply them by two and up more.
So here's some of your answers:
10:1
20:2
30:3
40:4
50:5
60:6
70:7
80:8
90:9
100:10
You would just continue this pattern.
1/5
4/8-3/10=1/5
#8 : x=15−y
#9:
#10: y=2A−x
#7: T=
65
