$18 = 14 + 0.20(t)
- 14
4 = 0.20t
Divide 4 by 0.20
t = 20
0.20 * 20 = 4
4 + 14 = 18
Because it only charged her for texts after 450, its 450 + 20.
470. She sent 470 texts that month.
your answer would be C, cause 1,000 has three zeros;
60.8 ÷ 1,000 = 0.0608

Answer:
No solutions.
Step-by-step explanation:
y = 5/2x + 2
2y = 5x + 8
Plug the first equation into the second.
2(5/2x + 2) = 5x +8
5x + 4 = 5x + 8
5x + 4 cannot equal 5x + 8, so this system of equations has no solutions.
