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!

What are the values of x and y <br>x=9/4 y=3/4<br>x=9/4 y=15/4<br>x=15/4 y=5/4<br>x=3/4 y=15/4

The complete question in the attached figure

we know that

in the triangle BDC
cos alfa=3/y----------> equation 1
sin alfa=x/y----------> equation 2


in the triangle ABD
cos alfa=4/5--------> equation 3
sin alfa=3/5---------> equation 4

then

Equal equation 1 and 3
3/y=4/5---------> y/3=5/4----------> y=15/4

Equal equation 2 and 4
x/y=3/5-------> x=3*y/5------------> 3*15/(4*5)-----> x=9/4

the answer is
<span>x=9/4 y=15/4</span>

Find the sum of the interior angles of a regular 29-gon.
aev [14]

Woah! A 29-gon. Impressive!

Sum of angles = 180(n-2) [where n is equal to the number of sides]

180(29-2)

180(27)

The sum of the interior angles of a regular 29-gon is 4860 degrees.

Hope that helps!

Solve the system using elimination.5x-9y=12x-9y=-12
NemiM [27]

Answer:

x = 6

y = 2

Explanation:

To solve the system using elimination, we need to multiply the second equation by -1, so the second equation is equivalent to:

x - 9y = -12

-1 (x - 9y) = -1 (-12)

-x + 9y = 12

Then, we can sum this equation and the first equation. So:

5x - 9y = 12

-x + 9y = 12

4x + 0 = 24

So, we can solve for x, as:

4x = 24

4x/4 = 24/4

x = 6

Then, we can replace x by 6 on the first equation and solve for y, so:

5x - 9y = 12

5(6) - 9y = 12

30 - 9y = 12

30 - 9y - 30 = 12 - 30

-9y = -18

-9y/(-9) = -18/(-9)

y = 2

Therefore, the solution of the system is x = 6 and y = 2
