6) Alex and Kendra arrive at the Texas State Fair with $51.50. What is the total number of rides they can go
on between them if they each pay the entrance fee of
$17 and rides are $2.50 each? write an equation then solve

Step-by-step explanation:

so first you need to make a equation

since we are trying to find out the amount of rides we can make that stand for x so..

we can first write it as 2.50x

(x = the numbers of rides)

since the entree fee is 17 dollars but they are two kids we have to times 17 by 2 giving us 34 we can add 34 dollars to the equation

34 + 2.50x

alex and kendra have only $51.50 dollars and they cant spend more then that so that means the whole equation has to equal $51.50

34 + 2.50x = 51.50

since we are trying to find the number of rides we can subtract 34 on both sides giving us

2.50x = 51.50 - 34

2.50x = 17.50

then we solve for x which you can divde 2.50 on both sides

x = 17.50 /2.50

x = 7

b.-4 units

all you   do is count how many times you move

3x + 4y -25 =0 represents the amount of change sianna should recieve
