Answer:
4
Step-by-step explanation:
Think of it this way. You have 2 sets of 2.
I I (This represents two)
I I (This represents the other two)
When you combine these, you get:
I I I I
If you count the tally marks, your answer is 4.
I believe the answer is the second one I am in the same class.

= 17 * 17 * 17 * 17 * 17 * 17 * 17 * 17 * 17 = 118,587,876,497
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.
Hope this helps! :)
Answer:
k = -4 or 2
Step-by-step explanation:
For the lines to be parallel, the lines would need to be the same slope. This means to find the slope of each we would take the difference of the rise over the run.
and
To find K, set them equal.
Factor the quadratic and solve for K.
k+4=0 so k=-4
k-2=0 so k=2
