7x - 3 = 60
7x = 63
x = 9
if you need to find for y
11y + 5 = 60
11y = 55
y = 5

Step-by-step explanation:
when you subtract 10.3 by 16% you get 1.6
Answer:
A. ![(-\infty, -4]\ or\ (2,\infty)](https://tex.z-dn.net/?f=%28-%5Cinfty%2C%20-4%5D%5C%20or%5C%20%282%2C%5Cinfty%29)
Step-by-step explanation:
Given:
The inequality is given as:

Now, consider the first inequality

Here, 'x' is less than or equal to -4. The values that are less than -4 are -5, -6, -7... so on. The inequality used is 'less than or equal to'. This means that -4 is included in the solution. So, we use a square bracket (closed interval) at the other end.
The inequality in notation form is thus, ![(-\infty,-4]](https://tex.z-dn.net/?f=%28-%5Cinfty%2C-4%5D)
Now, consider the other inequality 
The values of 'x' are greater than 2. The values that are greater than 2 are 3, 4, 5... and so on. Also, 2 is not included in the solution. So, we use open interval on either side.
Therefore,
in interval notation form is 
There is a conjunction 'or' used in the inequality. Therefore, the answer is:
A. ![(-\infty, -4]\ or\ (2,\infty)](https://tex.z-dn.net/?f=%28-%5Cinfty%2C%20-4%5D%5C%20or%5C%20%282%2C%5Cinfty%29)

Answer:
The answer would be 20
Step-by-step explanation:
75% is 75/100,
15 equals 75/100,
75/100 = 15/x.
x = 15 * 100 / 75 = 20.
the answer is 20.
