3, 9, 27, 81, 343, 729, … is a geometric sequence because each term is obtained by multiplying 3 to the preceding term.
Answer:
45
Step-by-step explanation:
Plug in the values into the equation
4(12) - 3
48 - 3 = 45
Answer:
<u>x = -2</u>
<u>y = -6</u>
Step-by-step explanation:
<u>Equating the equations</u> :
- x - 4 = 4x + 2
- 3x = -6
- x = -2
12,500 x 1.79 to find the price but 16,000 - 12,500 to get how many were left.
12,500 x 1.79 = $22,375 that they made from selling. 16,000 - 12,500 = 3,500 rolls left in the inventory. This question confused me so I just gave both answers.
