Answer:
Step-by-step explanation:
We can write two equations in the two unknowns using the given relations. Let g and b represent the costs of a round of golf and a turn in the batting cage, respectively.
5g +4b = 60 . . . . . Sylvester's expense
3g +6b = 45 . . . . . Lin's expense
Dividing the second equation by 3 gives ...
g +2b = 15 ⇒ 2b = 15 -g
Substituting into the first equation, we have ...
5g +2(2b) = 60
5g +2(15 -g) = 60 . . . . . substitute for 2b
3g = 30 . . . . . . . . . subtract 30, collect terms
g = 10 . . . . . . . divide by 3
__
2b = 15 -10 = 5 . . . . use the value of g to find b
b = 2.5 . . . . . . . . divide by 2
Mini golf costs $10 per round; batting cages cost $2.50 per turn.
Explanation:
Each box contains
The ratio that compares the number of blueberry bagels in one box to the number of onion bagels in one box will be calculated below as
This means that for every one onionbagels in the box, there are 2 blueberry bagels
Part B:
Given that there are 20 blueberry bagels, the number if onion bagels will be calculated below as
Hence,
The final answer is
Answer:
13a+27
Step-by-step explanation:
8a+12+5a+15= 13a+27
It will take you double the time, or 78 seconds.
