Distribute the 3 -> 12x - 6
Get rid of the 6 on the side with the variable -> 12x - 6 + 6 = 0 + 6
Get rid of the 12 -> 12x / 12 = 6 / 12
Simplify -> 1x = x = 1/2 or 0.5

Describe and correct the error in finding the tenth term of the arithmetic sequence 4, 12, 20, 28.

ycow [4]

Answer: The tenth term is 76

=======================================================

Explanation:

We use this arithmetic sequence formula to get the nth term

$a_n = a_1 + d(n-1)$

Plug in $a_1 = 4, \ d = 8, \ n = 10$ and you should get the following:

$a_n = a_1 + d(n-1)\\\\a_{10} = 4 + 8(10-1)\\\\a_{10} = 4 + 8(9)\\\\a_{10} = \textbf{76}\\\\$

The tenth term is <u>76</u>

---------

We can verify this by listing out the terms one by one. Start at 4, add on 8 each time, until you generate the 10th term. A table like the one shown below is a good way to keep track of all the terms.

$\begin{array}{c|c}\boldsymbol{n} & \boldsymbol{a_n}\\1 & 4\\2 & 12\\3 & 20\\4 & 28\\5 & 36\\6 & 44\\7 & 52\\8 & 60\\9 & 68\\10 & \textbf{76}\\\end{array}$

---------

In short, the error is with the "10" in the expression 4+10(8). The student should have used 9 instead. This is because of the n-1 term in $a_n = a_1 + d(n-1)$ which shifts everything one spot to the left.

OUT OF 32 STUDENTS IN A CLASS, 5 SAID THEY RIDE THEIR BIKES TO SCHOOL. BASED ON THESE RESULTS, HOW MANY OF THE 800 STUDENTS IN

svet-max [94.6K]

Let, the total number of students in school that ride the bike to school be "x"
Now,
Using ratio and proportion, we get,
$\frac{5}{32} = \frac{x}{800}$

$\frac{5}{32}*800 = \frac{x}{800} *800$

$\frac{4000}{32} =x$

$125 =x$

$x=125$

So, out of 800 students, 125 ride their bike to school.
