2x can represent the starting cost for a cookie.

5 can represent what goes to the boy scouts.

13 means the total amount of money you are paying.

Question:

Boy scouts sell cookies for x dollars. It costs $2 to start because that is labor of making the cookie. In addition to that, you need to pay $5 so it can go to supporting them. In total, you pay $13. How much money did you pay for cookies?

Solution:

2x + 5 = 12

~Subtract 5 to both sides

2x = 7

~Divide 2 to both sides

x = 3.5

Therefore, the cookie cost $3.50 each.

Best of Luck!

which pair of points forms line that does no intersect the line that passes through the points (5,7) and (7,7)?
Nuetrik [128]

Answer:

(8, -9), (11, -9)

Step-by-step explanation:

The points (5, 7) and (7, 7) are on a horizontal line in which the y-coordinates of all points are 7. The line has equation y = 7.

For a line to not intersect the line y = 7, it must be parallel to y = 7.

The answer is the pair of points which both have the same y-coordinate, and that y-coordinate is not 7.

From the choices you added to your comments, the only choice with two points with the same y-coordinate is (8, -9) and (11, -9). This is the answer.

Answer: (8, -9), (11, -9)

26=4v+3v+12 can anyone help?
motikmotik

Answer:

Step-by-step explanation:

Combine like terms

3v + 4v

26=7v+12

Subtract    12  from both sides of the equation

26-12

12-12

14=7v

Simplify

so subtract the 12's

Divide both sides of the equation by the same term

14 divided by 7

7 divided by 7

Simplify

do the division and move the term on the other side and it would be

v=2

Solution

 

v=2
