Okay, I'm going to assume that the part you're confused about is the part about how to use the number line to get the answer since the answer is given to you (it's -3).

So what you want to do is plot a point on -7. Since the line ends at -5, extend the line by drawing 2 vertical lines about to represent -6 and -7 (if you're reading it from left to right the -7 would come before -6 because it is a smaller value). Then you would want to hop 4 lines to the right, starting on -7. You would land on -3 which is the answer.

Ratio to percent 16:25

Tamiku [17]

<h3>Solution:</h3>

By multiplying it by 100, we can get the answer.

<h3>Given Ratio:</h3>

$\huge \purple {\tt {16:25}}$

<h3>Converting it into Percent, we get</h3>

$\huge \pink {\tt { \frac{16}{25} \times 100}}$

$\huge \red {\tt {= 16 \times 4}}$

$\huge \green {\tt {= 64\%}}$

<h2>Answer: 64%</h2>

Which recursive definition represents the sequence {2, 3, 5, 9, 17...}?

Gnesinka [82]

Let's analyze the sequence: {2,3,5,9,17...}.
3 = 2+1
5 = 3+2
9=5+4
17=9+8
So, every element of the sequence is obtained as sum from the previous element + (previous element -1)

y[n]=y[n-1] + (y[n-1]-1)

Addison pintó su habitación. Tenía 50

Nikitich [7]

Answer:

A(t) = -7.5t +50

Step-by-step explanation:

The computation is shown below:

Here we use the two point form i.e. presented below

(y - y_1) = (y_2 - y_1) ÷ (x_2 - x_1)

where,

Y = painted area

x = elapsed time

x_1 = 0

y_1 = 50

x_2 = 2

y_2 = 35

Now place the values to the above formula

So,

The area to be painted should be

A(t) = -7.5t +50
