Below are the solutions for a variable "x." State the solution that matches the graph below.
Aloiza [94]
We have a number line as indicated in the figure above. From this figure we know that the <em>x-values</em> <em>increase f</em><em>rom left to right</em>. So we need to write the solution<span> that matches the previous graph. Taking a look on the graph we see that x begins in -3 and closes in 8, that is, x <em>takes values from -3 to 8</em>. In a mathematical language this is given by the following statement: 

</span>x \in [-3,8]<span>

Solve the equation when x=12 1/3<br> Please show your work <br> 7x+8(x+1/4)=3(6x-9)-8
alina1380 [7]
7(12  1/3) + 8(12 1/3 + 1/4) = 3(6(12 1/3) - 9) - 8

12 1/3 = 12.33
1/4 = 0.25

7(12.33) + 8(12.33 + 0.25) = 3(6(12.33) - 9) - 8
86.31 + 8(12.58) = 3(73.98 - 9) - 8
86.31 + 100.64 =  3(64.98) - 8
186.95 = 186.94 - 8
186.95 ≠ 178.94

False. The x, when 12 1/3 does not work inside this equation
