false is the correct answer right
Fist u have to calculate how much it takes to reach the certain number for instance it takes 30 per gallon because 30 times 1 is 30. 30 times 2 is 60 and so on
Surface Area of Cylinder = 2πrh.
Radius, r = 7 cm, height = 12 cm.
Surface Area = 2*π*7* 12 = 168π cm²
π ≈ 3.14159
168π = 168*3.14159
Surface Area ≈ 527.79 cm²
Answer: 350
Explanation:
a = adult tickets
s = student tickets
║ a + s = 754
║s = a + 54
Plug s = a + 54 into a + s = 754
a + (a + 54) = 754
a + a + 54 = 754
2a + 54 = 754
2a = 754 - 54
2a = 700
a = 350
