Equation (A) C= 1.46n shows the relationship between the total cost of gasoline, c, and the number of gallons purchased, n.
<h3>
What is an equation?</h3>
- An equation is a formula in mathematics that expresses the equality of two expressions by connecting them with the equals sign =.
- The word equation and its cognates in various languages may have somewhat different definitions; for example, in French, an équation is defined as including one or more variables, whereas in English, an equation is any well-formed formula consisting of two expressions linked by an equals sign.
To find the right equation:
- In order to find the constant rate, we would divide 23.36/16 which gives you 1.46.
- That is the price of 1 gallon which would change depending on the amount of falling a purchased (n) and give you the total price of (C).
- So, C=1.46n
Therefore, equation (A) C= 1.46n shows the relationship between the total cost of gasoline, c, and the number of gallons purchased, n.

The complete question is given below:
The total cost of gasoline varies directly with the number of gallons purchased. Kathy pays $23.36 for 16 gallons of gasoline. Which equation
shows the relationship between the total cost of gasoline, c, and the number of gallons purchased, n?
A.C= 1.46n
B. n = 1.46c
C.C = 23.361
D. n = 23.36c
Answer:
20
Step-by-step explanation:
To solve, I converted the fraction to decimals
1.5/(2.25-0.75) X 1.8 = 1.5/1.5 X 1.8 = 1.8
3.2 - 1.20 = 2
3(2/30 - 1/30) = 3(1/30) = 3/30 = 1/10 = 0.1
2(2/64 / 1/16) = 2(32/64) = 2 (1/2) = 1
1.8/0.1 + 2/1 = 18 + 2 = 20
Answer:
the one you have selected is correct
Step-by-step explanation:
just remember when a number has absolute value bars around them it basically just makes it positive.
Answer:
17
Step-by-step explanation:
12 -6 divided by 3 is 2, so 15+2 is 17
