Answer:
x = 15, y = 50
Step-by-step explanation:
8x + 12 and 2x + 18 are same- side interior angles and sum to 180° , then
2x + 18 + 8x + 12 = 180
10x + 30 = 180 ( subtract 30 from both sides )
10x = 150 ( divide both sides by 10 )
x = 15
Then
8x + 12 = 8(15) + 12 = 120 + 12 = 132
3y - 18 and 8x + 12 are vertical angles and are congruent, so
3y - 18 = 132 ( add 18 to both sides )
3y = 150 ( divide both sides by 3 )
y = 50
Answer: 38 laps a day

Step-by-step explanation:
Hello! The tax rate is 8%. To find the total price paid for the television, let's first add 1 to the percentage in decimal form. 8% is 0.08. 1 + 0.08 is 1.08. Multiply that number by 330 to get 356.4. There. May pays a total of $356.40 for the television.
Note: When it comes to skipping straight to the total amount with tax, always add 1 to the tax rate (tax rate should be in decimal form). This will take you straight to the answer and save you some time and paper.
