<span>4x(5y-x)-5y(4x-y)=20xy-4x^2-20yx+5y^2=-4x^2+5y^2=5y^2-4x^2</span>
this relation is a function, y=30x
for every ax or 1 gallon, it goes 30 miles.
Assuming that this question is based on a graph, and that this graph tells us that people 50-64 years make up 35% of all the voters, then it would mean that
35%of 12000=

So, assuming that people at age 50-64 make up 35% of the voters, then 4200 of them voted.
Answer:
-6
Step-by-step explanation:

Firts, Let

be the repeated decimal that we are trying to convert , so

equation (1)
Next, lets find how many digits are repeating:
It is pretty cleat that 90 is repeating, and 90 has two digits. So we are going to multiply our equation by 100 to move the decimal point two places:

(2)
Subtract equation (1) from equation (2):


Solve for


We can conclude that 10.9090909091... expressed as a rational number, i<span>n the form pq where p and q are positive integers with no common factors, is </span>
