Answer:
Adult ticket is $7.5 while a child's ticket is $11
Step-by-step explanation:
Given data
Let the cost of an adult ticket be x
and the cost of a child ticket be y
The Seward family
2x+3y= 44.50---------1
The Sena family
3x+6y= 78-------------2
solve 1 and 2
2x+3y= 44.50 X2
3x+6y= 78 X1
4x+6y= 89
- 3x+6y= 78
x+ 0= 11
x= 11
put x= 11 in 1
2x+3y= 44.50
2*11+3y= 44.5
22+3y=44.5
3y= 44.5-22
3y= 22.5
y= 22.5/3
y= 7.5
Hence Adult ticket is $7.5 while a child's ticket is $11
8:45
-7:35
1:10 = 70 minutes
You can subtract that way or by knowing that there are 60 minutes in an hour and 8:35 to 8:45 is ten minutes you also get 70.
A candy store sells 8 pound bags of mixed almonds and cashews. If c pounds of cashews are in a bag,...
c=1 was already given as described. The store sells pound bags.
The rest of the description and question seem not to match. Maybe each bag contains 8 pounds of the two nuts. Eight pounds and some of this is of cashews. Now, c is how many pounds of cashews in one bag.
-
p=2.59%2Ac%2B1.72%288-c%29
You want to know the quantity of cashews if p=18.11 dollars per bag.
2.59c%2B1.72%2A8-1.72c=p
2.59c-1.72c=p-1.72%2A8
%282.59-1.72%29c=p-1.72%2A8
0.87c=p-13.76
