vitfil [10]3 years ago
3 0

Answer:

Step-by-step explanation:

6.4n - 1.2 + 3n + 8.2 = 19.22

So we can separate the variable side on the left, and the whole numbers on the right.

6.4n + 3n = 19.22 - 8.2 + 1.2

which gives us,

9.4n = 12.22

n = 1.3

A plumber chargers $25 for a service call plus $50 per hour of service. Write an equation in slope-intercept form for the cost,
daser333 [38]

25$ is the flat fee.  50$ is the amount charged per hour.  Therefore the equation is C=25+50h where c is the total cost and h is the amount of hours.  

C=25+50h

To find the amount of money for 8 hours simply plug in 8 for h and you get 400.  Don't forget to add the flat fee of 25.  The total cost for 8 hours of service is 425.

To find the amount of money for 10 hours of work, plug in 10 for h and you get 500.  Add 25 to 500 and you get 525 for a total of 10 hours of work.

Hope this helped...

Suppose a medium pizza at Vincent’s costs $6.75 plus $0.75 for each topping, and the cost of a medium pizza at Original Italian
lapo4ka [179]

Answer:

12 toppings

Step-by-step explanation:

There's a 60 cent difference in the base price, and the price of toppings is a 5 cent difference, so it would take 60/5 or 12 toppings to make up the difference.   r, you can make a chart.  Or you can do algebra and solve an equation:

6.75 + .75 x = 6.15 + .8x  where x is the number of toppings.  Subtract 6.15 from both sides.

.60 + .75x = .8 x     Subtract .75x from both sides

.60 = .05x         Divide both sides by .05
