Find the value of y when x equals 26 x+4y=54
pishuonlain [190]

Factor out the common term "2".

2(13x+2y) = 54

Now, divide both sides by 2.

13x + 2y = 54/2. <-- <u>We could not divide into a whole number so it's a fraction.</u>

<u />

Simplify 54/2 to 27.

13x + 2y = 27 <--- <u>Since we have a whole number without a letter, we are done with that side.</u>

<u />

Now, we subtract 2y from both sides.

13x = 27 - 2y

Divide both sides by 13.

x = 27 - 2y/13.

<h3>Therefore, we get <u>x = 27 - 2y/13</u></h3>

That would be our final answer.

Good luck on your assignment!

Rita will rent a car for the weekend. She can choose one of two plans. The first plan has no initial fee but costs $0.90 per mil
Artemon [7]

Let M = #miles driven

 

Plan 1:   .50M + 70  = total cost

Plan 2    .70M = total cost

 

To know how far she would drive to have an equal cost for either plan just set the equations equal to each other

 

.70M = .50M + 70

 

subtract .50M from both sides

 

.20M = 70

 

M = 70/.20 = 350 miles

 

Check the answser:

 

Plan 1:  .50(350) + 70 = 175 + 70 = $245

Plan 2:  .7(350) = $245

they are equal so our answer checks as correct

Give an example of a set of data displayed in a line graph
bazaltina [42]
Normally it’s like a ratio or starts with a graph on the side so you know what goes onto what part for example if you have a line graph you have 2 numbers.. so the y axis could be days and the x axis could be animals... so the graph would be showing how many animals per day... so it could be written out as 3:4 3,4 or how ever your teacher has you wrote them.. so then you would go on the X axis and find the 3 then go up 4 on the y axis and put a dot right at that point.
