Answer:
y=-5/3x+5/3
Step-by-step explanation:
Quantity of water Alberto had initially = 15 gallons.
Fraction of water that evaporated = 3/40
Now we have to find how much water is left.
Quantity of water left = Quantity of water Alberto had initially - Quantity of water evaporated.
Now let us find Quantity of water that was evaporated.
Quantity of water evaporated = 3/40 of 15 = 1.125 gallons
Quantity of water left = Quantity of water Alberto had initially - Quantity of water evaporated.
Quantity of water left = 15- 1.125 = 13.875 gallons
Answer: Quantity of water left is 13.875 gallons.
Answer:
(5, )
Step-by-step explanation:
Given the 2 equations
5x + 7y = 40 → (1)
3x - 7y = 0 → (2)
Adding the 2 equations term by term will eliminate the y- term
8x + 0 = 40
8x = 40 ( divide both sides by 8 )
x = 5
Substitute x = 5 into either of the 2 equations and solve for y
Substituting into (1)
5(5) + 7y = 40
25 + 7y = 40 ( subtract 25 from both sides )
7y = 15 ( divide both sides by 7 )
y =
solution is (5, )
