Answer: $66.7
Step-by-step explanation:
Answer:The equation for inverse proportion is calculated as xy=k.
When 20 people attend the picnic, the cost for each person was $50, then k will be= 20 × 50 = 1000
Recall that k = xy
For the second aspect of the question, x= 15, k= 1000.
k= xy
y = k/x
= 1000/15
= 66.7
If 15 people attend the picnic instead, the cost per person will be $66.7

Answer:
no solution (parallel lines)
Step-by-step explanation:
You observe that the coefficient in the second equation are all multiples of 3. Dividing that equation by -3 gives the two equations ...
The slopes are the same (2) and the intercepts are different (-11, 5), so the lines are parallel. There is no solution.
Question
<em>Emerson is making a punch that contains 60% grape juice and the rest lemon-lime soda. The punch has 2 liters of lemon-lime soda. Part A: Write an equation using one variable that can be used to find the total number of liters of grape juice and lemon-lime soda in the punch. Define the variable used in the equation and solve the equation. Hint: 0.6x represents the number of liters of grape juice in the punch. (5 points) Part B: How many liters of grape juice are present in the punch? Show your work. (5 points)</em>
Answer:
<u>5l = 0.4l(1) + 0.6l(2)</u>
<h2>
Step-By-Step-Explenation </h2>
5l = Total litres.
0.4l = 0.4 represents % of lemon-lime soda in litres.
0.6l = 0.6 represents % of grape juice in litres.
For grape juice, make L(1) = 0 and find for L(2), you will get 3L
For lemon-lime soda, make L(2) = 0 and find for L(1), you will get 2L
3L + 2L = 5L.
60% + 40% = 100%
I think this is right but i really tried.!
Hope this helps!
Answer:
D. y+3 = 6(x-1)
Step-by-step explanation:
i just wrote it out and i think thats the answer but not sure. hopefully this helps :)
It would be 15 minutes.
10/40 is 1/4, and 1/4 of an hour would be 15 minutes.
There ya go :)
