For the answer to the two questions above,
3x + 2y = 36.50 (I)
2x + 5y = 50 (II)
Eliminating x from the two equations by subtraction:
first we multiply equation I by 2 and equation II by 3
6x + 4y = 73
6x + 15y = 150
Subtracting the two,
-11y = -77
y = 7
He earns $7 at the coffee cart
Substituting y into equation I,
3x + 14 = 36.5
x = $7.50
So we can conclude that, he earns a greater wage of $7.50 at the library,
Answer:
2 gallons
Step-by-step explanation:
So say we make everything into cups. We know there is 4 cups in a quart and 2 cups in a pint. So if we do the math you are really adding
4 cups + 4 cups + 8 cups + 16 cups
So that would be 32 cups.
We also know there is 16 cups in a gallon. Since we know that then we can do
32 cups ÷ 16 cups
That would be 2 gallons!
Hope this helps!

Step-by-step explanation:
Answer: 0.9 is the decreasing factor.
Step-by-step explanation:
Here, The price of the ginger roots is G .
And, It there occurs the 10% off on this amount then,
The new price of the ginger is 90% of G.
That is, Final price of G = 
= 
= 0.9G
Since, 0.9 decreases the price of the ginger.
Therefore, It is called decreasing factor for the function which represents the price of the ginger.
9.4 - 6 = 3.4
12.8 - 9.4 = 3.4
16.2 -12.8 = 3.4
hence the difference between the terms is common and = 3.4
