1/3x + 2 = 4/3x - 5
2 + 5 = 4/3x - 1/3x
7 = x
y = 1/3(7) + 2
y = 7/3 + 2
y = 7/3 + 6/3
y = 13/3
solution is : (7,13/3) <=
Answer:
Step-by-step explanation:
formula=y-1=m(x-1)
sorry I dont know what the m is but the equation I have is
y-2=m(x-2)
The answer is x = 2 that's what I think
We have 20% and 60% solutions and need 80 ml of 50%
A) x + y = 80
B) .20x + .60y = (80 * .5)
Multiplying A) by -.2
A) -.2x -.2y = -16 Then adding this to B) we get
.4y = 24
y = 60 ml of 60%
x = 20 ml fo 20%

Answer:
86,475<em> </em>people live in poverty.
Step-by-step explanation:
We are given that the Total Cincinnati population is 
people.
We want to find the 
% of the Total population that lives in poverty. To do so we can use:
where 
is the amount of people that live in poperty. Plugging in values and solving we have:
However since here we are referring to number of people (i.e. population) we can not accept any irrational values so we need to round up our value so that
people live in poverty in Cincinnati.
