At a certain restaurant, milkshakes cost $4 and cheeseburgers cost $6. if al buys 1 milkshake and x cheeseburgers and spends at least $30 but no more than $46,
what is one value of x

5, 6 or 7

Step-by-step explanation:

If Al spends $30, the number of cheeseburgers bought is:

Since $30 is the minimum value, he has to buy at least 5 cheeseburgers.

If Al spends $46, the number of cheeseburgers bought is:

Therefore, Al bought between 5 and 7 cheeseburgers, which means that 5, 6 or 7 are possible values of x.

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
