Jack bought 3 slices of cheese pizza and 6 slices of mushroom pizza for a total of $22.50. Grace bought 1 slices of cheese pizza and 4 slices of mushroom pizza for a total cost of $11.80. What is the cost of one slice of each type of pizza

Equations:

3c + 4m = 12.50

3c + 2m = 8.50

Subtract and solve for "m"::

2m = $4

---

Ans: m = $2.00

Step-by-step explanation:

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
