The total cost of anja’s trip to the dentist was $628.35. she paid a flat fee of $89.95 which included the checkup and cleaning and then had 4 cavities filled, each of which cost the same amount. which shows the correct equation and value of x, the cost of each cavity filling?

89.95 + 4x =628.35

x = 134.60

Step-by-step explanation:

The trip to the dentist had a flat fee plus 4 cavities for a total cost of 628.35

fee + 4 * cost of cavity = 628.35

Let x = the cost of each cavity

89.95 + 4x =628.35

Subtract 89.95 from each side

89.95-89.95 + 4x =628.35-89.95

4x =538.40

Divide each side by 4

4x/4 =538.40/4

x =134.60

no, the equation would be invalid since they are both not equal.

step-by-step explanation:

here you got

4y-6+4y 2-9

first, you would simplify the equation on the form.

4y-6+4y 2-9

then, move all the terms that contains a y to the left and all the other terms to the right.

+4y-4y+-9-6

finally, you will simplify the left and the right side of the equation.

y=-3
