Answer:
1) 4
2) y <= 9
3) NO SOLUTION
4) 24
5) 5 cards
Step-by-step explanation:
1st pic) 2x + 7 = 15
2x + 7 = 15
-7 -7
2x = 8
divide by 2 to isolate x
x = 4
2nd pic) y - 3 <= 6
y - 3 <= 6
+3 +3
y <= 9
3rd pic) x + 0.5 = x + 6
x + 0.5 = x + 6
-0.5 -0.5
x = x + 5.5
NO SOLUTION
4th pic) 5m + 10 <= 130
5m + 10 <= 130
-10 -10
5m <= 120
divide by 5 to isolate the m
m <= 24
5th pic) 2c - 8 > 0
2c - 8 > 0
+8 +8
2c > 8
divide by 2 to isolate the c
c > 4
