The total cost of gasoline varies directly with the number of gallons purchased. kathy pays $23.36 for 16 gallons of gasoline. w
Shkiper50 [21]

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.

Help me, my teacher is going to kill me if i am wrong!! this is the last question and if I get it right I get a 100!! Please hel
GaryK [48]

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
