Answer:
2.75
Step-by-step explanation:
275% = 2.75 in decimal form. Percent means 'per 100'. So, 275% means 275 per 100 or simply 275/100. If you divide 275 by 100, you'll get 2.75 (a decimal number)
Answer:
y = - 10
Step-by-step explanation:
2x - 5y + 3 = 6x - 3y + 7
2(4) - 5y + 3 = 6(4) - 3y + 7
8 - 5y + 3 = 24 - 3y + 7
11 - 5y = 31 - 3y
11 - 11 - 5y = 31 - 11 - 3y
- 5y = 20 - 3y
- 5y + 3y = 20 - 3y + 3y
- 2y = 20
- 2y ÷ - 2 = 20 ÷ - 2
y = - 10
720/90 = 8 your answer is 8 hamburgers
