Hi

45 + 89.23568 = 67.09876543456 - ?
First, let's add
134. 23568 = 67.09876543456 - ?
Now let's be smart just for a second :)
We gonna replace this sign ? by x (x means the number we're looking for)
134. 23568 = 67.09876543456 - x
We are solving x, right ? So let's equal it.
Now, we have
-x = 67.09876543456 - 134.23568
You got it ? I hope so :)
Now we subtract
-x = 67.136915
Now we have the number but we can not NEVER left the x with a negative sign, never :)
To eliminate the negative sign we must divide both sides by -1
-x/-1 = 67.136915/-1
x/ = -67. 136915
That's the answer :)

If you have further question about the answer just let me know :)
Thanks !

Factor the expression completely.<br> 3x + 24

Umnica [9.8K]

Answer:

3(x+8)

Step-by-step explanation:

In order to factor the expression completely, you need to find the greatest common factor of both numbers, which would be 3 because 3 fits in both numbers without leading to weird decimals or fractions.

3(x+8) is the answer.

It costs $107 for 10 students and $137 for 15 students. How much does it cost for 12 students?

Anestetic [448]

$\bf \begin{array}{ccccccccc}
&&\stackrel{students}{x_1}&&\stackrel{price}{y_1}&&\stackrel{students}{x_2}&&\stackrel{price}{y_2}\\
% (a,b)
&&(~{{ 10}} &,&{{ 107}}~) 
% (c,d)
&&(~{{ 15}} &,&{{ 137}}~)
\end{array}
\\\\\\
% slope = m
slope = {{ m}}\implies 
\cfrac{\stackrel{rise}{{{ y_2}}-{{ y_1}}}}{\stackrel{run}{{{ x_2}}-{{ x_1}}}}\implies \cfrac{137-107}{15-10}\implies \cfrac{30}{5}\implies \cfrac{6}{1}\implies 6$

$\bf \stackrel{\textit{point-slope form}}{y-{{ y_1}}={{ m}}(x-{{ x_1}})}\implies y-107=6(x-10)
\\\\\\
y-107=6x-60
\implies 
y=6x+47\\\\
-------------------------------\\\\
\textit{how much will it be for }\stackrel{x}{12~students?}\qquad y=6(12)+47$
