Answer:
the middle ones
Step-by-step explanation:
Given:
3 pepperoni pizza for every 2 cheese pizzas sold
12 cheese pizzas sold.
This is a proportion problem:
3 : 2 = x : 12
a : b = c : d where ad = bc
a = 3 ; b = 2 ; c = x ; d = 12
3 * 12 = 2 * x
36 = 2x
36/2 = 2x/2
18 = x
18 pepperoni pizzas are sold during the 20 minute period.
I believe you can model a percent by using charts, diagrams, and e.t.c
Answer:
20
Step-by-step explanation:
because angle 5 is found on the same line as 45 degrees (don't remember what that's called), we can subtract from 180 to find
angle 5 = 135
angle 5 and 5x+35 are alternate interior angles, so they have the same value
135=5x+35
100=5x
20=x
