Answer:

Step-by-step explanation:

Formula for the nth term (an) = a1 + d(n - 1) where a1 = the first term and d = common difference.

So here the 13th term = 3 + 3(13 - 1)

= 3 + 3*12

= 39 (answer).

What is .336 written as a fraction?

marta [7]

The solution to the problem is as follows:

<span>Write the decimal number as a fraction (over 1)

0.336 = 0.336 / 1

Multiplying by 1 to eliminate 3 decimal places

we multiply top and bottom by 3 10's

Numerator (N) N = 0.336 × 10 × 10 × 10 = 336

Denominator (D) D = 1 × 10 × 10 × 10 = 1000 N / D = 336 / 1000

Simplifying our fraction = 336/1000 = 42/125</span>

Answer:

Inequality: $x+10\leq 12$

Inequality solved: $x\leq 2$

The graph is attached.

Step-by-step explanation:

You need to remember the meaning of the inequalities symbols:

: Less than.

$>$ : Greater than.

$\leq$ : Less than or equal to.

$\geq$ : Greater than or equal to.

Let be "x" the number of more songs Carlotta can download.

According to the information given in the exercise, she can download no more than 12 song files per week. This indicates that you must use the symbol $\leq$ .

Since she has already downloaded 10 song files this week, you can write the following inequality that represents this situation:

$x+10\leq 12$

In order to solve it, you must subtract 10 from both sides:

$x+10-10\leq 12-10\\\\x\leq 2$

Plot this result on a number line.

Since the symbol of the inequality is $\leq$ , the dot must be filled (Observe the number line attached).
