Answer:
x=1
Step-by-step explanation:
Simplifying
6x + 5 = 11x
Reorder the terms:
5 + 6x = 11x
Solving
5 + 6x = 11x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-11x' to each side of the equation.
5 + 6x + -11x = 11x + -11x
Combine like terms: 6x + -11x = -5x
5 + -5x = 11x + -11x
Combine like terms: 11x + -11x = 0
5 + -5x = 0
Add '-5' to each side of the equation.
5 + -5 + -5x = 0 + -5
Combine like terms: 5 + -5 = 0
0 + -5x = 0 + -5
-5x = 0 + -5
Combine like terms: 0 + -5 = -5
-5x = -5
Divide each side by '-5'.
x = 1
Simplifying
x = 1
6 + 2v
v = 9
6 + 2(9)
6 + 18
= 24

Answer:
46. <u>(3) 29</u>
47. <u>(1) y = -4x + 3</u>
48. <u>(3) 3</u>
49. <u>(3) -1/2</u>
50. <u>(4) 25x - 75</u>
Step-by-step explanation:
<u>Question 46</u>
- Let red marbles be 2x + 3 and black marbles be x
- 2x + 3 + x = 42
- 3x = 39
- x = 13
- No. of red = 2(13) + 3 = 29 marbles
- <u>(3) 29</u>
<u></u>
<u>Question 47</u>
- Parallel to a line means the slope is the same
- <u>(1) y = -4x + 3</u>
<u></u>
<u>Question 48</u>
- For the expression to be undefined, the denominator has to be 0
- x - 3 = 0
- x = 3
- <u>(3) 3</u>
<u></u>
<u>Question 49</u>
- Slope = -4 - 1 / 4 + 6
- Slope = -5/10
- Slope = -1/2
- <u>(3) -1/2</u>
<u></u>
<u>Question 50</u>
- Total = 25x
- Left 3 boxes at home = -3x = -3(25) = -75
- <u>(4) 25x - 75</u>
