At the Pizza place, 12% of the pizzas made last week had extra cheese. If 30 pizzas had extra cheese, how many pizzas in all were made last week?

250

Step-by-step explanation:

Given

12% of the Pizzas had extra cheese

If those pizzas were 30 in number

Suppose, x be the total Pizzas

So, 12% of x is 30

Thus, 250 Pizzas were maid last week

Let the distance x, and the time t

So, x = mt + c

Where m is the slope or rate of change and c is constant

Suppose the particle start traveling from the rest at t = 0

So, c = 0

∴ x = mt

Rises 4 feet in 9 seconds.

so, rate of change = distance per time = x/t = (4/9) (feet/seconds)

∴ m = 4/9

∴ x = (4/9) t

So, the relationship between time and the distance traveled

⇒  x = (4/9) t
