For this case we propose a system of equations:
x: Let the variable representing the number of children in the concert
y: Let the variable representing the number of adults at the concert
According to the assistance we have:

According to the cost we have:

Substituting the first in the second equation we have:

Thus, the concert was 375 adults.
On the other hand we have:

Thus, the concert was 1125 children.
In total they were:
people
ANswer:
The concert was 1500 people
Answer:
In standard form, it would be 0.0000001901!
Step-by-step explanation:
As you can see, if the exponent is negative, the answer would be a decimal so moving the decimal place 7 times to the left, that would be your answer.
Answer:
44 minutes
Step-by-step explanation:
I would set this up as a proportion-
20 x
5 11
Then cross multiply-
20 x 11 = 220
Divide-
220/5 = 44
It would have him 44 minutes to read 11 pages
Answer:
I would go for translation as that relates to a language I guess.
Step-by-step explanation:
You need the total of square feet of the mural before you can divide 50 square feet to it and get your answer of how many pints of paint you will need.
For example.
Mural size is 2800 square feet
1 pint per 50 square feet
Work out problem.
2800 square feet ÷ 50 square feet= ?
= 56 pints of paint
