Answer:
g(N)=3 + 7n
80 = 3 + 7n
move the variable to the left hand side so
80 - 7n = 3
now do 3 - 80 to get -7n = -77
now divide both sides by -7 to get
n=11
2nd
p(x) = 4x
6= 4x
so swap the equations so its
4x = 6
next divide both sides by 4
x = 3/2 or 1.5
Step-by-step explanation:
23 cards.
After Monday, Esteban has 12 cards.
After Tuesday, Esteban has 12 + 24 = 36 cards.
He gave to his sister x cards.
36 - x = 13
36 = 13 + x
23 = x
Volume = πr²h
3.14 * (18 : 2)² * 12 =
3.14 * 9² * 12 =
3.14 * 81 * 12 =
254.34 * 12 =
3052,08 mm³
