Jada has $20 to spend on games and rides at a carnival. Games cost $1 each and rides cost $2 each. Which equation represents the relationship between the number of games, x and the number of rides, y, that Jada could do if she spends all her money?

x + 2y = 20

Step-by-step explanation:

number of games = x

cost of 1 game = $1

cost of x games = $1*x = $x

number of rides = y

cost of 1 rides = $2

cost of y rides = $2*y = $2y

Total cost for x games and y rides = $x + $2y

given that he can spend all which he has

and he has $20

Then

Total cost for x games and y rides would be equal to total money had

thus

$x + $2y = $20

$ gets cancelled from both sides

thus

relationship between  x and y will be

x + 2y = 20  Answer

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )
