Daryll is given $30 and spends $1.25 per day on basketball cards. On the same day, Larry is given $2 and saves $1.25 per day. The graph shows the amount of money each boy has compared to the number of days that have passed.



How much money will each boy have on the day that the boys have the same amount of money?
$11.20
$30.00
$2.00
$16.00

Answers

$16.00 because that’s where the points hit using the title on the y axis

The boys have $16 on 11th day.

What is Graph?

The graph is simply a structured representation of the data. It aids in our comprehension of the data. The numerical information gathered through observation is referred to as data.

Following the creation of a research question, data is continuously gathered through observation. The information is subsequently arranged, condensed, categorised, and visually portrayed.

In a line graph, the information or data is represented as a series of markers, or dots, and is then connected to one another by a straight line.

Usually, data that varies over time is represented with a line graph.

Given:

Daryll is given $30 and spends $1.25 per day on basketball cards.

Larry is given $2 and saves $1.25 per day.

So, to find the same day for both from the graph.

We have to focus on where the lines for two persons intersects, it will the on same day how much money they have.

Hence, the boys have $16 on 11th day.

-2(4r - 6) Mathhhhhhhhh pls

Answers

Answer: -8r+12

Step-by-step explanation:

Answer:   -8r + 12

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

Explanation:

The outer term -2 is multiplied by each term inside

-2 times 4r = -8r-2 times -6 = 12

Then those results are added to get -8r + 12 as our final answer. We cannot combine these terms because they are not like terms.

I used the distribution property, also known as the distributive property.

That says a*(b-c) = a*b - a*c

In this case, a = -2, b = 4r, and c = 6.
