Answer:
The statement is true
Step-by-step explanation:
The denominators of the fractions are 3 and 4. The least common multiple of those numbers is 12, making the least common denominator 12.
Answer:
45 eggs left
Step-by-step explanation:
if they had 4 crates and each crate has 18, then we have a total of 72 eggs
subtract 27 eaten eggs from 72
72-27=45
they have 45 eggs left
For this problem you have yo set up two equations.
White shirts = w Yellow shirts = y
1st: w + y = 21
2nd: 9.95w + 11.50y = 235.30
Now we're going to do system of equations using substitution.
If w + y = 21, then y = 21 - w
If y = 21 - w, then you can substitute this in the second equation for y.
9.95w + 11.50(21 - w) = 235.30
9.95w + 241.5 - 11.50w = 235.30
-1.55w + 241.5 = 235.30
-1.55w = -6.2
w = 4, so 4 whites shirt were sold.
Now I'm finding out how many yellow shirts were sold using one of the two equations at the top.
w + y = 21
4 + y = 21
y = 17
So 17 yellow shirts were sold and 4 white shirts were sold.
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:
![x = 3y](https://tex.z-dn.net/?f=x%20%3D%203y)
According to the cost we have:
![3x + 7y = 6000](https://tex.z-dn.net/?f=3x%20%2B%207y%20%3D%206000)
Substituting the first in the second equation we have:
![3 (3y) + 7y = 6000\\9y + 7y = 6000\\16y = 6000\\y = \frac {6000} {16}\\y = 375](https://tex.z-dn.net/?f=3%20%283y%29%20%2B%207y%20%3D%206000%5C%5C9y%20%2B%207y%20%3D%206000%5C%5C16y%20%3D%206000%5C%5Cy%20%3D%20%5Cfrac%20%7B6000%7D%20%7B16%7D%5C%5Cy%20%3D%20375)
Thus, the concert was 375 adults.
On the other hand we have:
![x = 3 (375) = 1125](https://tex.z-dn.net/?f=x%20%3D%203%20%28375%29%20%3D%201125)
Thus, the concert was 1125 children.
In total they were:
people
ANswer:
The concert was 1500 people
