Answer:
74.5%
Step-by-step explanation:
The total number of people sampled is 1000 people.
There are 745 people who where corrective lenses.
Percent is (part)/(whole); in this case, the part is 745 and the whole is 1000, so:
745/1000 = 74.5%
Thus, the answer is 74.5%.

You should find that your system doesn't have solutions. This is also confirmed by the fact that the determinant of the matrix of the coefficient of the variables x, y and z is equal to zero.
Answer:
x = -2
Step-by-step explanation:
- 3 x - 6x = -18x
- 4 - 18x + 9 = 41
9 - 4 = 5
- 18x + 5 = 41
- 18x = 41 - 5
- 18x = 36
36 divided by -18 is -2
