What is are the solutions to | x+4 |= 3x-5?
bonufazy [111]

Answer:

x = \frac{9}{2}

Step-by-step explanation:

The absolute value always returns a positive value but the expression inside can be positive or negative, that is

x + 4 = 3x - 5 ( subtract 3x from both sides )

- 2x + 4 = - 5 (subtract 4 from both sides )

- 2x = - 9 ( divide both sides by - 2 )

x = \frac{9}{2}

OR

-(x + 4) = 3x - 5

- x - 4 = 3x - 5 ( subtract 3x from both sides )

- 4x - 4 = - 5 ( add 4 to both sides )

- 4x = - 1 ( divide both sides by - 4 )

x = \frac{1}{4}

As a check

Substitute these values into the equation and if both sides are equal then they are the solutions

| \frac{9}{2} + 4 | = | \frac{17}{2} | = \frac{17}{2}

right side = \frac{27}{2} - 5 = \frac{17}{2}

left side = right side , thus x = \frac{9}{2} is a solution

check second solution

| \frac{1}{4} + 4 | = |  \frac{17}{4} | = \frac{17}{4}

right side =   \frac{3}{4} - 5 = -   \frac{17}{4}

right side ≠ left sides, hence not a solution

Duane And his family are playing a game Dwayne scores 11 points each tile matches 1/3 point model the solution with an equation
Luba_88 [7]

Answer:

33 tiles

Step-by-step explanation:

Given

1\ tile = \frac{1}{3}\ points

Required

Determine the number of tiles in 11 points

Represent this with x. So, we have:

1\ tile = \frac{1}{3}\ points

x = 11\ points

Cross Multiply

x * \frac{1}{3} = 11 * 1

Multiply through by 3

3*x * \frac{1}{3} = 11 * 1*3

x = 33
