Not quite sure sorry edit : Oh sorry I supposed to add this in the comment section
1. x/6>3 multiply both sides by 6
x>18
So a. and c. are both greater than 18
2.
-4x<32 divide both sides by -4 (and remember to reverse direction of inequality sign because of multiplication/division by a negative value!)
x>-8
So three value of this infinite set are -7, -6, -5 :P
3.
x/6≥3 multiply both sides by 6
x≥18
So three value of this infinite set of solutions are 18,19,20
Step-by-step explanation:
Hmm I'm not sure but (no) I think
6 pounds = $16.50
1 pound = $16.50 ÷ 6
=$2.75
$16.50 = 6 pounds
$1 = 6 ÷ $16.50 = 4/11 pounds (0.36363636......)
Answer: The driver has $95.25 after the last ride.
Step-by-step explanation: First we need to know how much money he recieved from each ride. Multiply 3.5 with each number.
$3.5 x 10 = $35
$3.5 x 5.5 = $19.25
$3.5 x 19 = $91
Now add them up.
$35 + $19.25 + $91 = $145.25.
However, he spends $50 on gas. So subtract $145.25 and $91.
$145.25 - $91 = $95.25.
Therefore, the driver has $95.25 after the last ride.
