Answer:
a + c = 150
Step-by-step explanation:
adults + children = 150
a + c = 150
so to find the number of adults we need to subtract the number of children from the total number of attendees.
a + c - c = 150 - c the the number of adults is
a = 150 - c
Take 5 1/2 and put it over 100. This is a complex fraction which means 5 1/2 divided by 100. Convert 5 1/2 to an improper fraction, 11/2, and multiply it by the reciprocal of 100, 1/100. The answer is 11/200.
Remember that a system of equations (two lines) only has solutions if the lines cross. In this case, the lines are parallel, which means that they will never cross. Therefore, there are no solutions.
Hope this helps! :)
To find the total cost, you need to add these numbers together
you get 7.37 as your answer, but you need to round this to the nearest whole number.
rounding 7.37 will make it 7.
the total cost is about $7
