Answer:

<em>The expression is equal to 22</em>

Step-by-step explanation:

<u>Expression Evaluation</u>

We are given the expression

10 + 2p - 3r

And it's required to evaluate it when p=3 and r=2. This means we have to replace the letter for the value assigned to them, as follows:

10 + 2*3 - 3*(-2) = 10 + 6 - (-6)

= 10 + 6 + 6

= 22

The expression is equal to 22

The graph below shows the relationship between two variables.
Sergeeva-Olga [200]

The graph adequately represents the following case

"The number of employees at a store increased at a constant rate for 5 years. There was a decrease in the number of employees for 2 years. Then the number of employees increased at a greater constant rate for the next few years."

Step-by-step explanation:

To solve the above-mentioned problems we need to filter the results through analysing the options given-

We have to keep in mind that-

  1. For an increase in value/quantity- the graph would be on an upswing
  2. For decrease in value/quantity- The graph would be in declining mode
  3. For constant value- horizontal graph line parallel to the x-axis

Now going through the options-

option 1:-

David drove at a constant speed initially- throughout the graph no horizontal line is present, hence this condition does not represent the graph.

option 2:-

test scores increased and then decline- In this condition only two phases are mentioned, whereas in the graph three different phases are present. Hence this condition too does not represent the graph.

option 3:-

After the period of slow.- The graph starts with an upswing. hence this condition too does not represent the graph.

option 4:-

Employees increased and then declined and then again increased. All the above condition corroborates to the above-mentioned graph. hence this condition is represented in the graph

guapka [62]

Hey!!

Total angle - 180

... 2x + 4 + 2x - 9 + x = 180

... 4x - 5 + x = 180

... 5x - 5 = 180

... 5x = 185

... x = 185 / 5

... x = 37


Hope my answer helps!!

Victor writes 10 more poems than ann.Ann writes 10 poems. How many poems does victor writes?
tino4ka555 [31]

Victor writes 20 poems

<em><u>Solution:</u></em>

Given that victor writes 10 more poems than Ann

Also given that Ann writes 10 poems

To find: number of poems written by Victor

<em><u>From given information, we can frame a equation as:</u></em>

number of poems written by Victor = 10 more poems than Ann

number of poems written by Victor = 10 + number of poems written by Ann

Substituting the given , number of poems written by Ann = 10 , we get,

number of poems written by Victor = 10 + 10 = 20

Thus victor writes 20 poems
