Studio fee:$8 per hour <br> Vase:$10

aleksandrvk [35]

Answer:

4.5 hours

Step-by-step explanation:

So, let's write a function p(x) which represents the total cost.

Let's let x represent the amount of hours.

The cost of a piece is a constant 10.

And there is a $8 fee per hour. In other words:

$p(x)=8x+10$

We spent a total of $46.

So, substitute in 46 for p(x) and solve for x:

$46=8x+10$

Subtract 10 from both sides:

$36=8x$

Divide both sides by 8:

$x=36/8$

Reduce:

$x=4.5$

So, we spent about 4.5 hours.

SEVENTH GRADE ALGEBRA PLS HELP

strojnjashka [21]

Answer:

x = 22 (each friend started with 22 action figures)

Step-by-step explanation:

After buying 8 more action figures, each friend has x + 8 action figures. Because there are 5 friends, the new total number of action figures is 5(x + 8), which we are told is equal to 150. Dividing both sides of this equation by 5 yields x + 8 = 30, and subtracting 8 from both sides yields x = 22.
