Arnold's pizzeria sells their pizzas "by fraction". you can buy 1/6 of a pizza for $2.75, 2/5 of a pizza for for $6, 1/2 of a pizza for $8, or 2/3 of a pizza for $12. which of these offers the best deal?

2/5 of a pizza for for $6 offers the best deal.

Step-by-step explanation:

Pizzas are sold by fraction at Arnold's Pizzeria.

1)You can buy 1/6 of a pizza for $2.75. This means that the cost of a full pizza at this rate would be

6 × 2.75 = $16.5

2) 2/5 of a pizza for for $6, This means that the cost of a full pizza at this rate would be

6 × 5/2 = $15

3) 1/2 of a pizza for $8. This means that the cost of a full pizza at this rate would be 8 × 2 = $16

4) 2/3 of a pizza for $12. This means that the cost of a full pizza at this rate would be 12 × 3/2 = $18

Therefore, the best deal is 2/5 of a pizza for for $6

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
