Answer:
x = -5
Step-by-step explanation:
7 × 2 + 5 - x = 6 × 2 + 10
Multiply.
14 + 5 - x = 12 + 10.
Combine like terms.
19 - x = 24
Isolate x (I'm going to add x and subtract 24 from both sides to avoid changing signs)
-5 = x
Final answer
x = -5
Answer: The answer is A, 40.
2 x 2 = 4 + 4 x 4 = 16
4 + 16
= 20 + 2 x 40
20 + 80 = 100
(x = 40)
Answer:
The inequality is 
The greatest length of time Jeremy can rent the jet ski is 5 and Jeremy can rent maximum of 135 minutes.
Step-by-step explanation:
Given: Cost of first hour rent of jet ski is $55
Cost of each additional 15 minutes of jet ski is $10
Jeremy can spend no more than $105
Assuming the number of additional 15-minutes increment be "x"
Jeremy´s total spending would be first hour rental fees and additional charges for each 15-minutes of jet ski.
Lets put up an expression for total spending of Jeremy.

We also know that Jeremy can not spend more than $105
∴ Putting up the total spending of Jeremy in an inequality.

Now solving the inequality to find the greatest number of time Jeremy can rent the jet ski,
⇒ 
Subtracting both side by 55
⇒ 
Dividing both side by 10
⇒
∴ 
Therefore, Jeremy can rent for 
Jeremy can rent maximum of 135 minutes.
Answer:
