Abuffet restaurant has one price for adults and another price for children. the taylor family has two adults and three children, and their bill was $40.50. the wong family has three adults and one child. their bill was $38. which system of equations could be used to determine the buffet price for an adult and the price for a child? a. x y = 40.50 x y = 38 b. 2x 3y = 40.50 x 3y = 38 c. 2x 3y = 40.50 3x y = 38 d. 2x 2y = 40.50 3x y = 38

step-by-step explanation:

most likely the answer is a.

alice wins if a total of 5 is rolled. finn wins if a total of 9 is rolled.

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
