Answer:
BC = 7
Step-by-step explanation:
AB + BC = AC
39 + BC = 46
BC = 46 - 39
BC = 7
2p = 4
p = 2
-2p = 4
p = -2
answer p = -2 and p =2
Given:$7/child
$10/adult
Total people = 700
Total money = $6,400
First, make two equations.
Let a = # of adults & Let c = # of children.
Let p = total people
1. a+c = 700
2. 10a+7c = 6,400
Then, rearrange the equation to solve for a variable.
c = 700-a
Substitute (700-a) for c, or the # of children in the second equation.
10a+(700-a) = 6400
9a+700 = 6400
9a+700-700 = 6400-700
9a = 5700
9a/9 = 5700/9
a = 633 = # of adults attended700-633
= c =
66 = # of children attended
