8 pounds of chamomile tea must be mixed to make a mixture that costs 14.63 per pound.
Step-by-step explanation:
We are given the following in the question:
Chamomile tea:
Unit cost = 18.20 per pound
Amount = x pounds
Total cost =
Orange tea:
Unit cost = 12.25 per pound
Amount = 12 pounds
Total cost =
Total mixture:
Unit cost = 14.63 per pound
Amount = (12+x) pounds
Total cost =
We can write the equation that cost of mixture is equal to cost of chamomile tea and orange tea.
Thus, 8 pounds of chamomile tea must be mixed to make a mixture that costs 14.63 per pound.

Answer:
See explanation below.
Step-by-step explanation:
To make use of the tools they give you, start at the point (-5, -2) which you know is a point the line goes through, then draw a line that goes towards the right following the rule given by the slope "1/2" (rise/run) which means that every 2 units to the right, you go one unit up. so from the point -5 in x, you go to the point -3 in x, and from -2 in y you move up one unit to -1
Therefore the line joins (-5, -2) to the point (-3, -1)
Answer:
Step-by-step explanation:
(0;2) and (4;5)
(x1;y1) ; (x2;y2)
y=mx+b
m=(y2-y1)/(x2-x1)
m=(5-2)/4-0)
m=3/4
y=mx+b=> 2=3/4 *0+b; => b=2
So, y=3x/4 +2
Answer: L=45, W=9
Step-by-step explanation:
Perimeter P=108 so if L=5W,
P=2(L+W)=2(5W+W)=2(6W)=12W
108=12W
W=108/12=9
L=5*9=45
