On Tuesday the cafeteria sold pizza slices and burritos. The number of pizza slices sold was 20 less than twice
the number of burritos sold. Pizza sold for $2.50 a slice
and burritos for $3.00 each. The cafeteria collected a
total of $358 for selling these two items.
a) Write two equations with two variables to represent the
information in this problem. Be sure to define your
variables.
b) Solve the system from part (a). Then determine how
many pizza slices were sold.

55/i dont know i do it for the points

step-by-step explanation:

the answer is 18 units because there are 18 small cubes inside the rectangle

hope this and p.s i am also in k12

step-by-step explanation:

a

step-by-step explanation:

given the 2 equations

- x + y = - 2 → (1)

2x - 3y = 4 → (2)

multiplying (1) by 2 and adding to (2) will eliminate the x- term

- 2x + 2y = - 4 → (3)

add (2) and (3) term by term

(2x - 2x) + (- 3y + 2y) = (4 - 4), simplifying gives

- y = 0 ⇒ y = 0

substitute y = 0 in either of the 2 equations for corresponding value of x

substituting in (2) gives

2x = 4 ( divide both sides by 2 )

x = 2

solution is (2, 0 ) → a
