Answer:

x=-4

Step-by-step explanation:

1.4x +2.6x = -16

combine like terms (numbers with numbers, and numbers with variables together)

4x = -16

get x by itself (isolation)

x = -4

Your friend uses the equation c=50p to find the total cost c for the number of people p internal local amusement park create a t
AnnZ [28]

We are given equation c=50p.

c is the total cost and p is the number of people.

Let us take number of people by groups of 10, 20, 30,40 people.

Note: We can take any positive integer for number of people in a group.

Now, we need to plug p=10, 20, 30,40 one by one in given function c=50p to find the costs c.

Plugging p=10, we get

c= 50*10 = 500.

Plugging p=20, we get

c= 50*20 = 1000.

Plugging p=30, we get

c= 50*30 = 1500.

Plugging p=40, we get

c= 50*40 = 2000.

So, we can create a table as.

Number of people (p)           Total cost (c)

--------------------------------------------------------------------

         10                                      500

         20                                     1000

         30                                     1500

         40                                     2000

What is the best prediction of the amount of money earned when the lemonade stand has been open for 9 hours
abruzzese [7]

Answer:  $50

Step-by-step explanation:  Draw a line through the apparent center of the scattered dots. See where that line intersects 9 in the time scale (x-axis numbers) and the dollars earned scale (y-axis numbers)

It could be 50 or 55, but since there are a few more dots below the apparent midline, it may be best to use the lower estimate.
