3 is not a factor of 32. Therefore, x will not be a whole number. X is equal to about 10.66

Answer:

x=3

Step-by-step explanation:

I am assuming that your equation is:

$\sqrt{8x + 12} + 4 = 10$

Subtract 4 from both sides to get:

$\sqrt{8x + 12} = 6$

Square both sides to get:

$(\sqrt{8x + 12})^{2} = {6}^{2}$

$8x + 12 =3 6$

$8x =24$

Divide both sides by 8 to get:

$x = \frac{24}{8} = 3$

Teddy has 23 boxes of juice packed and plans to pack 3 additional boxes each hour. Charely has 7 boxes packed and plans to pack

Vadim26 [7]

The equation is already set up for you. All you need to do is solve for x, the number of hours.

23 + 3x = 5x + 7 original equation
23 - 7 = 5x - 3x combine like terms by subtracting 7 and 3x from both sides
16 = 2x simplify
16/2 = x divide both sides by 2 to isolate x
8 = x solve for x
Therefore, the answer is 8 hrs.
