Answer:
The price of the regular gasoline is $2.46, while the premium is $2.67.
Step-by-step explanation:
Let the price of regular gasoline be "x", while the price for the premium be "y", The sum of the amount of each type of gas multiplied by its cost should be equal to the total paid, therefore:

We also know that the premium gas costs 0.21 more than the regular one, therefore:

We can apply the second expression on the first, in order to solve for "x".


The price of the regular gasoline is $2.46, while the premium is $2.67.
Answer:
c) 1
Step-by-step explanation:
f(x) = g(x)
-x+2 = 5x-4
+x +x
2 = 6x -4
+4 +4
6 = 6x
(divide both sides by 6)
1 = x
Answer:
4
Step-by-step explanation:
Because 1/12 is a simplified version of x /48
2x^2 -2x - 12 is a polynomial with a GCF of 2.
it can be written as 2(x^2 - x - 6) just by taking out the 2
and if we factor the expression in the parentheses we get
2(x - 3)(x + 2)
Answer:
21
