Answer:
y = 25 degrees
Step-by-step explanation:
We start with 115° and x -
115° + x = 180°
x = 180° - 115°
x = 65°
The sum of all of the angles of a triangle will <em>always</em> be 180 degrees -
x + y + 90° = 180°
We substitute x with 65° -
65° + y + 90° = 180°
y = 180° - 65° - 90°
y = 90° - 65°
y = 25°

Answer:
Michael bought 18 tacos and 9 burritos.
Step-by-step explanation:
Since at a particular fast food restaurant, tacos cost $ 1.29 and burritos cost $ 2.19, and Michael spent a total of $ 42.93 at the restaurant to buy food for a party, if he purchased half as many burritos as tacos, to determine how many tacos did he buy, the following calculation must be performed:
1.29 x 20 + 2.19 x 10 = 47.7
1.29 x 16 + 2.19 x 8 = 38.16
1.29 x 18 + 2.19 x 9 = 42.93
So Michael bought 18 tacos and 9 burritos.
