Answer:
40 !
Step-by-step explanation:
You get 12.6
After the decimal starts the the tenth place. In order to round to the tenth place, we need to know the hundredth place which is the 7. If the hundredth place is 5 or greater then we round up and if it's 4 or lower then we keep the tenth place the same number as it is before.
Since the hundredth place is greater than or equal to 5, we round up the tenth place to 6. If you have any questions then leave a comment. Good luck!
Answer:
x = 1 (Option C)
Step-by-step explanation:
3x - 4y = -5 (1)
-3x - 4y = -11 (2)
On adding
3x - 4y - 3x - 4y = -11 + 5
6x = 6
x = 6/6
x = 1
Hey, sorry this took so long for you to get an answer. Let me try.
<h2>Answers:</h2>
Part A: Answer choice C.
Part B: 6 people can come to the bowling alley.
<h2>Explanation:</h2>
For Part A, I've concluded that the answer is C. Ben can't spend more than $80, so it has to be equal to or less than 80. The flat fee is $45, and the cost per person is variable, $5.50p, so I combined all of those together and got <em>45+5.50p ≤ 80 .</em>
This is answer choice C.
And for Part B, I got 6. I got this answer from doing 80, the maximum cost, minus the flat rate, 45. Then, I divided this number by 5.50 to get the number of friends that could be paid for. I originally got 6.3636... but I rounded down because you can't have 0.3636... of a friend to come to the bowling alley.
Hopefully this isn't too late. Good luck.
