The answer is 78.54 . I promise u it’s correct
Since a cube has 6 sides, we can divide 294 by 6, so we have the area of one side. Since it is a cube, we can just square root that, and you get 7 cm.
Given:
Admission to the local movie theater is $3 for each child and $7 for each adult.
A group of 12 people pay $64 admission.
To find:
The number of children in a group.
Solution:
Let the number of children be x and number of adults be y.
According to the question,
Total persons : ...(i)
Total cost : ...(ii)
Multiply equation (i) by 7 and subtract the result from (ii).
Divide both sides by -4.
Therefore, the number of children is 5.
Answer:
for brand A it required 41 bags and for brand B is required 56 bags
Step-by-step explanation:
The computation is shown below:
Let us assume Brand A be x
And, brand B be y
Now according to the question
The following equations are
8x + 7y = 720
4x + 6y = 500
Multiply by 2 in equation 2
8x + 7y = 720........(1)
8x + 12y = 1000..........(2)
Now subtract equation 1 from equation 2
5y = 280
y = 56 bags
And, x is
8x + 7(56) = 720
8x + 392 = 720
8x = 328
x = 41 bags
hence, for brand A it required 41 bags and for brand B is required 56 bags
