Answer:

Step-by-step explanation:
1. Subtract 10 from both sides. Then:

2. Divide both sides by -2. Notice that the direction of the symbol of the inequality will change. Then:

3. Add 22 to both sides. Then:

4. Divide both sides by -7. Notice that the direction of the symbol of the inequality will change. Then:

5. Subtract 30 from both sides. Then:

6. Divide both sides by -5. Notice that the direction of the symbol of the inequality will change. Then:

7. Subtract 13 from both sides. Then:

8. Add 12 to both sides. Then:

18.725 = 18725/1000 = 3745/200 = 749/40 = 18 29/40
so, your answer is 18 29/40
Answer:
Answer:
3x + 3y = 0
7x - y = 8
Step-by-step explanation:
Answer:

Step-by-step explanation:
In order to find r we have to square both sides of the equation

The *square root* sign cancels out the *squared* sign therefore:

Answer:
x + y = 13
98x + 115y = z
Step-by-step explanation:
Let x represent the time spent taking class in Westside community college
Let y represent the time spent taking class in Pinewood community college
Let z represent the combined total amount paid for the class fees.
The total combined time for the two school is given as:
x + y = 13.
For the combined total amount; we multiply the price for each school with the time spent on the school and sum them together.
Westside: 
Pinewood: 
The combined total amount represented as z is given as:
z = 98x + 115y
