Given:

Line l and line m are parallel.

Co-interior angles are (12x - 8)° and 104°.

To find:

The value of x.

Solution:

Sum of co-interior angles = 180°

12x° - 8° + 104° = 180°

12x° + 96° = 180°

Subtract 96° from both sides.

12x° + 96° - 96° = 180° - 96°

12x° = 184°

Divide by 12° on both sides.

x° = 7°

x = 7

The value of x is 7.

Your friends ate at a restaurant and left a $2.40 tip. They left a 15% tip. What was the cost of their bill before the tip?
zhannawk [14.2K]

Answer:

16$ is the bill

Step-by-step explanation:

so 2.40 is 15% of the bill, what i'd do is first divide 2.40(15%) by 3 to get 5% which can make this much easier, 2.40÷3=0.80. this means that 1.60 is 10% since 0.80 is 5%. so now we do 1.60×10=16$
