a. you would need to know how many toppings are going on the pizza. the price changes depending on the number of toppings, because each one adds 35 cents.
b. x equals the number of toppings. the number of toppings will change from pizza to pizza, so you put a variable in its place so you can use the same equation for every pizza.
c. 12 + 0.35x this is because the base price of every pizza is $12, then you add the number of toppings (x) multiplied by the price per topping ($0.35).
d. 12 + 0.35x when x=3 is 12 + 0.35(3) = 12 + 1.05 = $13.05
You haven't shared "the two patterns below."
Let me guess: 5+5 = 10 and 10+15 = 25. Thus, 5+5+10+15 = 10+25 = 35.
If this is not correct, please ensure that you have shared this problem accurately and completely.
Answer:
15:20
Step-by-step explanation:
We can simplify the ratio to 3:4
after doing that we can multiply both sides by 5 giving us
15:20 as our answer
Or you can cross multiply
9 : 12 = 15 : x
Now we have 9x = 180
divide both sides by 9 and we get
x=20
which would work giving us the ratio of 9 : 12 = 15 : 20
