Solve for a. 1/3(21-3a)=6-a

OverLord2011 [107]

Answer:

no solution

Step-by-step explanation:

Given

$\frac{1}{3}$ (21 - 3a) = 6 - a ( multiply through by 3 to clear the fraction )

21 - 3a = 18 - 3a ( subtract 21 from both sides )

- 3a = - 3 - 3a ( add 3a to both sides )

0 = - 3 ← not possible

This indicates the equation has no solution

42,591 to the nearest thousand

Nutka1998 [239]

Answer:

43,000

Step-by-step explanation:

Remember, the tipping point is 50%.

42,591, if the hundreds to one's place is 500 or more, the number 591, it increases the thousands value by 1

Since 591 is greater than 591, the new number will increase from 42,591 to 43,000

A towns population has been growing literally

Tresset [83]

$\bf \begin{array}{ccll}
\stackrel{\textit{years since 2000}}{t}&\stackrel{population}{p}\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
2&29400\\
5&36000
\end{array}\\\\
-------------------------------\\\\
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
&({{ 2}}\quad ,&{{ 29400}})\quad 
% (c,d)
&({{ 5}}\quad ,&{{ 36000}})
\end{array}$

$\bf slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{36000-29400}{5-2}\implies \cfrac{6600}{3}
\\\\\\
2200
\\\\\\
% point-slope intercept
\stackrel{\textit{point-slope form}}{y-{{ y_1}}={{ m}}(x-{{ x_1}})}\implies \stackrel{y}{p}-29400=2200(\stackrel{x}{t}-2)
\\\\\\
p-29400=2200t-4400\implies p(t)=2200t+27200$

how many in 2007? well, 2007 is 7 years after 2000, thus set t = 7,to get p(t).
