Answer:
the answer is x=4. you have to use the distributive property on both sides then begin solving for x.

Answer:
Use the distributive property to get 10x+20=5x+40. Subtract 5x from both sides to get 5x+20=40. Subtract 20 from both sides to get 5x=20. Divide 5 from both sides to get x=4.

x=4

x=4

11/2÷3=? Write as a mixed number if possible

Ruth's car traveled 120 miles during the first race. During the second race, it traveled 124 miles. If the car averaged 123 miles over the first three races, how far did it travel during the third race?

Simplify

3 - 7n^2 + 3n^3 - (6n^3 - 1 - 5n^2)

Simplify brackets

3 - 7n^2 + 3n^3 - 6n^3 + 1 + 5n^2

Collect like terms

(3 + 10) + (-7n^2 + 5n^2) + (3n^3 - 6n^3)

Simplify

**4 - 2n^2 - 3n^3**

**Answer:**

**-3n^3 - 2n^2 + 4.**

**Step-by-step explanation:**

(3-7n^2+3n^3)-(6n^3-1-5n^2)

First distribute the negative over the second parentheses:

= 3 - 7n^2 + 3n^3 - 6n^3 + 1 + 5n^2

Now simplify like terms:

= **-3n^3 - 2n^2 + 4 **(answer).

7 goes in 7, 100 (Digit!) times no remainder

7 goes in none so it is now 64 not 6

7 goes in 64, 9 times with remainder 1

So it is 109 remainder 1 or 109, 1/7

7 goes in 7, 100 (Digit!) times no remainder

7 goes in none so it is now 64 not 6

7 goes in 64, 9 times with remainder 1

So it is 109 remainder 1 or 109, 1/7

IF

63x+81

= 9(7x+9)

63+81x

= 9(7+9x)

IF

63x+81

= 9(7x+9)

63+81x

= 9(7+9x)

63 + 81 = **9(7 + 9)**

Your final answer is**9(7 + 9)**.
