Answer:

7 cars

Step-by-step explanation:

Gemma earns $575 a week plus $180 in commission for each car sold

She earned $1835 last week

Therefore the amount of cars sold can be calculated as follows

= $575 + $180(7)

= $575 + $1260

= $1835

Hence 7 cars were sold

Your cell phone plan cost $39.99 per month plus $.13 for each text message you send or receive. You have at most $45 to spend on

Dafna11 [192]

Answer:

At most 38 text messages.

Step-by-step explanation:

Let x represent number of text message you send or receive.

We have been given that the cell phone plan charges $.13 for each text message you send or receive. So amount charged for sending or receiving x text messages would be $0.13x$ .

We are also told that your cell phone plan cost $39.99 per month, so total cost of monthly bill would be $0.13x+39.99$ .

Since you can spend at most $45, so total cost of x messages should be less than or equal to 45 as:

$0.13x+39.99\leq 45$

$0.13x+39.99-39.99\leq 45-39.99$

$0.13x\leq 5.01$

$\frac{0.13x}{0.13}\leq \frac{5.01}{0.13}$

$x\leq 38.5384615$

Therefore, you can send or receive at most 38 text messages.

Find the value of x

tiny-mole [99]

Answer:

x = 150

Step-by-step explanation:

What we need to do is first use the sum of interior angles theorem to find the total sum of this odd hexagon.

n = sides of the shape.

(n-2)*180° = Sum of interior angles

For us this would be 720° total. Now make an equation

121 + 96 + 101 +162 + 90 + x = 720

Then we simplify

570 + x = 720

-570 -570

And then subtract 570 on both sides and we get our answer.

x = 150

Here is a growing pattern of sequences:

Nadusha1986 [10]

Answer:

A, C, F

Step-by-step explanation:

The first figure is drawn using 8 squares. The next uses 11 squares, and the one shown in Step 3 uses 14 squares. The numbers of blocks follow the sequence ...

8, 11, 14

which begins with 8 and increases by 3 from one step to the next. This constant increase from one term to the next makes it an arithmetic sequence.

<h3>explicit form</h3>

The general term, an, of an arithmetic sequence can be written in terms of its first term, a1, and its common difference, d, as ...

an = a1 +d(n -1)

When the first term is a1=8, and the common difference is d=3, this becomes ...

an = 8 +3(n -1)

which simplifies to

an = 8 +3n -3 = 3n +5

Written in functional form, these explicit equations are ...

f(n) = 8 +3(n -1) . . . . . matches choice A

f(n) = 3n +5 . . . . . . . . matches choice F

<h3>recursive form</h3>

The recursive form of the definition of a sequence starts with the first term, then tells you how to obtain the next term from that. Here, the first term is ...

f(1) = a1 = 8

and each term is 3 more than the last:

f(n) = 3 +f(n-1) . . . . . . . . . 3 is added to the previous term

Together, this is ...

f(n) = 8, f(n) = 3 +f(n -1) . . . . . matches choice C
