Ok so we know he used over 700 because he was charged more than 40. Then we take the $8.10 and divide 0.45 into it. This then gives you 18 more minutes. Then add 18 to 700 and you get 718 min.
When you say "Which number ...", I expect to see a list of choices at the
end of the question, and I get very upset when there's nothing there.
9h + 15 > 55
Subtract 15 from each side: 9h > 40
Divide each side by 9 : <em> h > 40/9</em>
Any number greater than (4 and 4/9) satisfies the inequality.

Answer:
g(L) = 175L - L²
Step-by-step explanation:
350 = 2(length + width)
length + width = 175
Let L be the length,
L + width = 175
width = 175 - L
Area = length × width
g(L) = L(175 - L)
g(L) = 175L - L²
Answer:
x<-3
Step-by-step explanation:
-2(x+3)>9+3x - Distribute
-2x-6 > 9+3x - Subtract 3x to both sides
-5x-6 > 9 - Add 6 to both side
-5x > 15 - Divide -5 to both sides
Integer switches: x < -3 - Answer
