Answer:
66 minutes
Step-by-step explanation:
<u>Solve for speed</u>

Answer: Sarah’s neighbor offers to pay her $5 for every shark tooth she finds on the beach. After collecting only three shark’s teeth, Sarah decides to share the opportunity with her friend John. Sarah can find shark teeth twice as fast as John, but she can earn even more money with his help.
Sarah can use the expression 5(2j + 3 + j) to represent the amount of money they can earn. Therefore, The total money they earned is $5 x 15 = $75.
2x + y = 4
2x - y = 8
-------------add
4x = 12
x = 12/4
x = 3
2x + y = 4
2(3) + y = 4
6 + y = 4
y = 4 - 6
y = -2
okay....so x = 3 and y = -2
3x - y = ?
3(3) - (-2) = ?
9 + 2 = 11....so ur answer is 11
