X = 1.004, y = 124,996 are your answers
Answer:
The cost for 1 necklace is $3.
Step-by-step explanation:
With the information provided, you can say that the amount spent in bracelets and necklaces is equal to the price per bracelet for the number of bracelets plus the price per necklace for the number of necklaces, which is:
c=3x+2y, where:
c is the total cost
x is the price per bracelet
y is the price per necklace
Now, you can say that c=21 and x=5 and solve for y to find the price per necklace:
21=(3*5)+2y
21=15+2y
21-15=2y
6=2y
y=6/2
y=3
According to this, the answer is that the cost for 1 necklace is $3.
Answer:
They can fill 15 gallons per hour.
Step-by-step explanation:
In order to find the number of gallons, we first need to find the number of cups. We can find that by multiplying the number of juice boxes by the volume of a juice box.
300 * 0.8 = 240 cups
Next, we divide the number of cups by the number of cups in a gallon (16).
240/16 = 15 gallons
assuming you means k = log_2(3) [as log(2)3 is the same thing as 3log(2) due to multiplication being commutative]
given log(ab) = log(a) + log(b)
log_2(48) = log_2(3) + log_2(16)
