-20 x 2 or -10 x 4 both equal -40
-2 x 3 = 6
Answer: -11 meters
Step-by-step explanation:
so for the waters surface, we are going to call that 0. if bob is at 15 meters below 0, then -15+4=-11, so he would be at-11 meters in relation to the waters surface.

Answer:
The cost of the rides are 3 tickets
And 1 ticket per game
The ride and game cost 3 tickets and 1 ticket for each respectively.
Step-by-step explanation:
Step 1 of 5
Let <em>a</em> be the number of tickets per ride costs. And <em>b</em> be the number of tickets per game costs.Thus from the given, we get the equations. For Scott, <em>5a+4b=19</em> For Isaac, <em>7a+2b=23</em>
Step 2 of 5
Multiplying the equation 2 by 2, we get <em>5a+4b=19→1</em> <em>14a+4b=46→2</em>
<em>Step 3 of 5</em>
<em>By subtracting both the equations, we get </em>
<em>(−)5a+4b=1914a+4b=46 </em>
<em>_____________ </em>
<em>−9a =−27 </em>
<em> a=−27−9⇒a=3</em>
Step 4 of 5
<em>Substituting the above value in the equation 1, we get5(3)+4b=1915+4b=194b=19−154b=4b=44⇒b=1</em>
<em>Step 5 of 5 </em>
<em>The solution is (3,1).The cost of the rides is 3 tickets per ride.The cost of the games is 1 ticket per game.</em>
