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
Answer:
x= to 5
Step-by-step explanation:
Two line with the same slope are parallel, if two parallel lines have a different y-intercept they will never cross each other.
(Any two lines with different slopes will always intersect at some point)
Answer:
845.6306
Step-by-step explanation:
Firstly this is annuity based
Let, investment at beginning of year = <em>x</em>
Then value at year 1 end = x + (8.2%
x)
Value at end of year 2 = (x + 0.082x) + (8.2%
(x + 0.082x))
Now this value = $990
Therefore,
990 = (x + 0.082x) + ((x + 0.082x)
8.2%)
990 = x + 0.082x + 0.082x + 0.006724x = 1.170724x
x = 990/1.170724 = 845.6306
I’m not that sure but
B is (-2,2)
A is (-4,-2)
C is (2,2)
Hope it helps!!
