Think of this situation as a system of equations.
let y be the price of hotdogs
let x be the price of hamburgers
5y + 2x = 8
2y + 5x = 9.50
now use your solution method of choice

Answer:
of a second
Step-by-step explanation:
We can convert each time into fractions.
11.74 is the same thing as 
and 11.69 is the same thing as 
.
We know that 11 - 11 = 0, so we can focus on the fractions for now.
Let's subtract 
from 
.
.
We can now simplify 
by dividing both the numerator and denominator by 5.

Answer:
The sum of 2 numbers is 52. Express the product of the numbers, P, as a function of one of the numbers, x.
the answer is p(x) = -x² + 52x
Step-by-step explanation:
let the two numbers be x and y
the sum of the two numbers = x + y
≡ x + y = 52
make y the subject of equation
y= 52 - x
to express the product of the numbers, P, as a function of one of the numbers, x. implies that
P(x) = x(-x + 52)
finally,
p(x) = -x² + 52x
Answer:
