Because a prime number has to be greater than 1.
Answer:
Apple = €0.20
Banana = €0.60
Step-by-step explanation:
Let A represent the price of an apple and B represent the price of a banana:
4A + B = €1.40
7A + B = €2.00 multiply first equation by -1 and then find the sum of the two equations:
-1 x (4A + B) = 1.40
-4A - B = -1.40
7A + B - 4A - B = 2.00 - 1.40
3A = 0.60 divide both sides by 3
A = 0.20 now we can use this information to calculate the price of a banana
4*0.20 + B = 1.40
0.80 + B = 1.40 subtract 0.80 from both sides
B = 0.60

Answer:
An inverse variation is something of the shape:
y = k/x.
Knowing that the point (5, 10) is included in this equation, we can obtain the value of k.
10 = k/5.
10*5 = k
k = 50
Then our inverse variation is:
y = 50/x.
Now we can give any value of x in order to find another point that is included in the variation, for example, if x = 5
y(5) = 50/5 = 10
then the point (5, 10) does also belong to the inverse variation.
if x = 50
y(50) = 50/50 = 1.
then the point (50, 1) does also belong to the inverse variation.
Answer:
1.88 pounds
Step-by-step explanation:
First, find the total amount of sugar, since there were 2 shipments
22.56(2)
= 45.12
Then, divide this by 24:
45.12/24
= 1.88
So, each canister had 1.88 pounds of sugar
