Which of these equations have no solution? Check all that apply.
Llana [10]
2(x + 2) + 2 = 2(x + 3) + 1
2x + 4 + 2 = 2x + 6 + 1
2x + 6 = 2x + 7 - NO SOLUTION
(subtract 2x from both sides, then 6 = 7 FALSE)

2x + 3(x + 5) = 5(x – 3)
2x + 3x + 15 = 5x - 15
5x + 15 = 5x - 15 - NO SOLUTION

4(x + 3) = x + 12
4x + 12 = x + 12 - ONE SOLUTION

4 – (2x + 5) = (–4x – 2)
4 - 2x - 5 = -4x - 2
-2x - 1 = -4x - 2  - ONE SOLUTION

5(x + 4) – x = 4(x + 5) – 1
5x + 20 - x = 4x + 20 - 1
4x + 20 = 4x + 19 - NO SOLUTION

Nellie made 734 quarts of soup that she put into 14-quart containers. She filled each container completely before starting to fi
Vikentia [17]

Amount of soup Nellie made = 734 quarts

Amount of soup each container contains = 14 quarts

So, the number of containers Nellie filled = \frac{734}{14} = 52.42

So, Nellie filled 52 containers completely.

24x^2 - 45x - 21 = 0
Norma-Jean [14]
24x^2-45x-21=0\\
3(8x^2-15x-7)=0\\
8x^2-15x-7=0\\
\Delta=(-15)^2-4\cdot8\cdot(-7)=225+224=449\\
\sqrt{\Delta}=\sqrt{449}\\
x_1=\dfrac{-(-15)-\sqrt{449}}{2\cdot8}=\dfrac{15-\sqrt{449}}{16}\\
x_2=\dfrac{-(-15)+\sqrt{449}}{2\cdot8}=\dfrac{15+\sqrt{449}}{16}

HELPP! this is my second time uploading this question:,,)

Answer:

<em>X can equal 22.5 </em>

Step-by-step explanation:

I've set up the equation below:

\frac{2}{3} +\frac{5}{x} =\frac{8}{9}

With this equation, as any addition equation goes, we assume it to be like this:

A +  B = C

so

C - A = B

that means,

\frac{8}{9} -\frac{2}{3} =\frac{5}{x}

The easiest thing to do is to make 2/3 have the same denominator as 8/9, we do this by...

\frac{2}{3} *\frac{3}{3} = \frac{6}{9} \\

So...

\frac{8}{9} -\frac{6}{9} =\frac{2}{9} =\frac{5}{x}

We now know that 5 over x equals 2 over nine. We can determine x by cross multiplying as follows:

\frac{5}{x} =\frac{2}{9} \\2x = 45\\x=22.5

So, x is 22.5, making the equation indeed solvable.
