linear equation to find the length of a phone call that cost $7.45.

Respuesta :

1.75+.30x=7.45
this is the answer i’m pretty sure

Answer:

1.75 + 0.3x = 7.45; 19 minutes

Step-by-step explanation:

The cost of the phone call is found by 1.75 + 0.30 multiplied by the number of minutes the calls lasts.  The cost of the call is 7.45 so 1.75 + 0.3x = 7.45.  Begin by subtracting 1.75 from each side of the equation.  That leaves 0.3x = 5.7.  Then divide both sides by 0.3.  This gives x = 19.
