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
<u> -7 -7</u>
2x = 8
divide by 2 to isolate x
<u>x = 4</u>
2nd pic) y - 3 <= 6
y - 3 <= 6
<u> +3 +3</u>
<u>y <= 9</u>
<u />
3rd pic) x + 0.5 = x + 6
x + 0.5 = x + 6
<u> -0.5 -0.5</u>
x = x + 5.5
NO SOLUTION
4th pic) 5m + 10 <= 130
5m + 10 <= 130
<u> -10 -10</u>
5m <= 120
divide by 5 to isolate the m
<u>m <= 24</u>
5th pic) 2c - 8 > 0
2c - 8 > 0
<u> +8 +8</u>
2c > 8
divide by 2 to isolate the c
<u>c > 4</u>
a. 6 x 5 = 30
b. 5.6 x 5 = 28
a. 20 devided by 5 = 5.6
b. 36 devided by 5 = 7.2 (i dont know, that sounds like a pretty tall person to me)

That depends on what the digits are. It could be anywhere between zero times and infinite times. If both are the same digit and not zero, then the tenth is ten times the size of the hundredth.
