Answer: is that supposed to be a riddle lol I have no clue what that is
Answer:
∠ a = 60° , ∠ b = 120°
Step-by-step explanation:
Supplementary angles sum to 180° then
x - 40 + x + 20 = 180 , that is
2x - 20 = 180 ( add 20 to both sides )
2x = 200 ( divide both sides by 2 )
x = 100
Then
∠ a = x - 40 = 100 - 40 = 60°
∠ b = x + 20 = 100 + 20 = 120°
Let x be the number of new laptops and y be the number of tablets that
the company should buy. The equations that best show the given
conditions are as follows,
x + y = 30
515x + 285y = 11080
Solving simultaneously for the values of x and y gives an answer of x = 11 and y = 19.
Thus, the business should buy 11 laptops and 19 tablets.
