ANSWER

EXPLANATION
The given line JKL is a straight line. The angle on a straight line is 180 degrees.
This implies that the sum of the angles ![\begin{gathered} Solve for x in the equation above:[tex]\begin{gathered} x=180-30 \\ x=150\degree \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20Solve%20for%20x%20in%20the%20equation%20above%3A%3C%2Fp%3E%5Btex%5D%5Cbegin%7Bgathered%7D%20x%3D180-30%20%5C%5C%20x%3D150%5Cdegree%20%5Cend%7Bgathered%7D)
That is the value of x.
Erika $21
3k of cinnamon
1g of gummies
Irene $39
3k of cinnamon
3k of gummies
c= cost of 1 kilogram of cinnamon
g= cost of 1 kilogram of gummies
Erika's Equation
3c + 1g= $21
Irene's Equation
3c + 3g= $39
Solve for one variable in equation one and substitute it in the other equation.
3c + 1g= 21
subtract 3c from both sides
g= 21 - 3c
Substitute g=21 - 3c in equation
3c + 3g= $39
3c + 3 (21 - 3c)= 39
multiply all in parentheses
3c + 63 - 9c= 39
63 - 6c= 39
subtract 63 from both sides
-6c= -24
c= $4
Substitute c=4 in equation to find g
3c + g= 21
3(4) + g= 21
12 + g= 21
subtract 12 from both sides
g= $9
ANSWER: The price of 1 kilogram of cinnamon red hots is $4. The cost of 1 kilogram of gummies is $9.
