2300 people came to the ball game last week. This week there was a 13% decrease. How many people attended the football game this week. The problem can be represented by the expression p-0.13p.

Answers

Answer: 2001 people attended the football game this week.

Step-by-step explanation:

Given: Total people came to the ball game = 2300

Decrease percent = 13%

Number of people attended the football game this week =  p-0.13p, where p= number of people attended football last week.

for p= 2300

Number of people attended the football game this week =  2300- 0.13 x (2300)

=2300-  299

= 2001

hence, 2001 people attended the football game this week.

Answers

Answer:

76.3

Step-by-step explanation:

Answer:

C = 75°

Step-by-step explanation:

The interior angles of a triangle will always add up to 180°, so all we have to do is find the missing variable.  

To do this, we first add up the two angles we do know.

—> 65 + 40 = 105      

Now that we have the total of the other two angles, simply subtract 105 from 180.

—> 180 - 105 = 75

We now have our answer!

Answer:

394 miles.

(its hard to explain but you need to spit 1356 and add 284 to one half)

Answer:

820

Step-by-step explanation:

Let us call the trip back x. The trip back is 284 miles smaller than the trip back, so our equation can be:

x + x + 284 = 1356

2x + 284 = 1356

2x = 1072

x = 536

The we do 536 + 284 because the trip there was 284 miles longer, so that is 820

This is my second attempt first is the brainiest!

Answers

Answer:

A:59 B:48

Step-by-step explanation:

A triangle is equal to 180 degrees. So the equation would be

73+x+(x-11)=180. To find the value of x, add all of the same values

73-11+x+x which is equal to 62+2x=180. Then subtract 62 from both sides

62-62+2x=180-62  so the equation is now 2x=118 now you divide each side by 2 to get x=59. now to get angle b you subtract 11 from 59 to get 48

i posted the same question but they didn’t tell me how they got it so could someone show me how they got the answer pleaseee

Answers

Answer:

y= -6

Step-by-step explanation:

-4y - 20 + 19 = -y + 17        *add y on the right to get rid of -y

+y                    +y                then add it to -4y

-3y - 20 + 19 = 17               *add 20 to the left to get rid of -20  

     +20           +20              then add it to 17

-3y + 19 = 37                      *subtract 19 from the left to get rid of 19

       -19    -19                      then subtrcat 19 from 37 as well

-3y = 18                             *now we want to divide both sides by -3 to

-3      -3                               get y by it's self

y = -6                                *no we're left with y = -6 :D

Which table represents y as a function of x?​

Answers

Answer:

Table number 1

Step-by-step explanation:

explanation: If the X-inputs (the exes) repeats then the table is not a function.

In the first table all the x-inputs are different.

Hence, table first is the correct answer which [tex]y[/tex] is a function of [tex]x[/tex].

What is a input ?

The input is what goes into the function and the output is what comes out of the function.

Here as per the information, table first is correct because when the values  [tex]x[/tex] change then it is a function of [tex]y[/tex] , and as per this concept table first is correct.

Hence, table first is the correct answer which [tex]y[/tex] is a function of [tex]x[/tex].
