vova2212 [387]
10 cheese pizzas

use  simple ratio, 3:2 (3 pepperoni for every 2 cheese)
to make the ratio bigger, we substitute the "3" pepperoni for "15" pepperoni. then take the new amount, 15/3 original, you get 5. then multiply the 2 original cheese pizzas by that 5, and you get 10 cheese pizza's. 

hope that helps

Write the inequality shown by the graph
Lostsunrise [7]

Answer:

A

Step-by-step explanation:

equation of the line graphed

(y-4)/(2-4) = (x+6)/(0+6)

(y-4)/(-2) = (x+6)/6

y-4 = (x+6)/-3

y = (x+6)/-3 +4

y = (x+6-12)/-3

y = -1/3x + 2

so the answer is A

Is (6, –2) a solution to this system of equations? y = –1/6 x − 1 y = 1/6 x − 3
Liula [17]

Answer:

Yes, (6, -2) is a solution to the given system of equations.

Step-by-step explanation:

Please write  y = –1/6 x − 1 y = 1/6 x − 3 as follows, for greater clarity:

y = (–1/6)x − 1

y = (1/6)x − 3

Let's actually solve this system:

y = (–1/6)x − 1

y = (1/6)x − 3

-----------------------

2y = -4, or y = -2

Now find x.  Arbitrarily we choose to use the first equation for this purpose:

y = (-1/6)x - 1.  We set y = -2 and find x:    -2 = (-1/6)x - 1

Combining the constants, we get -1 = (-1/6)x, or 6 = x

Yes, (6, -2) is a solution to the given system of equations.
