Answer: B) <14,0>
Answer: it will take 4 games for both costs to be the same.
Step-by-step explanation:
Let x represent the number of games that must be bowled before the costs become the same.
At Paul's bowling alley,it costs 4.00 to rents shoes and 3.50 to bowl each game. This means that the cost of bowling x games at Paul's bowling alley would be
3.5x + 4
At Maggie's bowling alley, it costs 3 to rent shoes and 3.75 to bowl each game. This means that the cost of bowling x games at Maggie's bowling alley would be
3.75x + 3
Therefore, for the costs to be the same, the number of games would be
3.5x + 4 = 3.75x + 3
3.75x - 3.5x = 4 - 3
0.25x = 1
x = 1/0.25 = 4
Answer:
b= -8
Step-by-step explanation:
b-6=-14
add 6 to -14 but its a negative so, you subtract -14 to 6.
----------
b= -8

Correct Question:
5 (u + 1) - 7 = 3 (u - 1) + 2u.
Solve for u
Answer:
See explanation below
Step-by-step explanation:
In this given question, we are required to find u.
Given the equation:
5 (u + 1) - 7 = 3 (u - 1) + 2u
Required:
Solve for u
To find u, first simplify both sides individually.
Simply 5 (u + 1) - 7:
Expand the parenthesis:
5u + 5 - 7
Collect like terms:
5u - 2
<em>Simplify 3 (u - 1) + 2u:</em>
Expand the parenthesis:
3u - 3 + 2u
Collect like terms:
3u + 2u - 3
5u - 3
Bring both simplified equations together:
5u - 2 = 5u - 3
5u - 5u - 2 = -3
-2 = -3
Since -2 ≠ -3, there is no solution.
Therefore, we can say the equation is invalid.
