2x+5+(6x+1)
you distribute an invisible one to get them out of the parentheses
2x+5+6x+1
You then add like terms
8x+6
Simplifying
37 + 8x = 4(7 + -1x)
37 + 8x = (7 * 4 + -1x * 4)
37 + 8x = (28 + -4x)
Solving
37 + 8x = 28 + -4x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '4x' to each side of the equation.
37 + 8x + 4x = 28 + -4x + 4x
Combine like terms: 8x + 4x = 12x
37 + 12x = 28 + -4x + 4x
Combine like terms: -4x + 4x = 0
37 + 12x = 28 + 0
37 + 12x = 28
Add '-37' to each side of the equation.
37 + -37 + 12x = 28 + -37
Combine like terms: 37 + -37 = 0
0 + 12x = 28 + -37
12x = 28 + -37
Combine like terms: 28 + -37 = -9
12x = -9
Divide each side by '12'.
x = -0.75
Simplifying
x = -0.75
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:
Answer:
20in
Step-by-step explanation:
The unit rate in the equation is 20.
Option C) is the correct answer.
<u>Step-by-step explanation</u>:
Step 1 :
In the given equation y = 20x
where,
x ⇒ total number of hours for tutoring
20 ⇒ the cost per hour of tutoring
y ⇒ the total cost for total hours of tutoring
Step 2 :
Unit rate refers to the value per hour.
Here, the cost for 1 hour of tutoring is $20.
∴ The unit rate is $20 per hour of tutoring.
