Answer:
35
Step-by-step explanation:
20% * x = 7
20/100 * x= 7
x = 7 *100/20 (7*100÷20)
you add them then divide the result (310)/(10) = 31 cards
Answer:
x<-3 or x>-1
Step by step explanation:
Start with -5x>15. To get x by itself, we have to divide each side by -5. When we do that we get x<-3. (Don't forget to flip the sign when dealing with negative · and ÷.) Now answer the second equation. x-5>-6 To get x by itself, add 5 to both sides to get x>-1. Now we have x<3 or x>-1.
