For this case, the first thing we must do is define a variable:
 g: number of gallons of gas.
 c (g): total cost.
 We then have a linear function of the form:
 c (g) = 2.19 * g
 Answer:
 
A function notation to describe the relationship between the total cost c (g) and the number of gallons purchased is:
 
c (g) = 2.19 * g

For each equation given below, write ONE related equation. a) x + 5 = 18 b) 66x =330
GenaCL600 [577]

Answer:

x = 13 ; x = 5

Step-by-step explanation:

The easiest related equation to get is simply solving for x:

a) x + 5 = 18

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 5 from both sides:

x + 5 (-5) = 18 (-5)

x = 18 - 5

x = 13*

b) 66x = 330

Isolate the variable, x. Divide 66 from both sides of the equation:

(66x)/66 = (330)/66

x = 330/66

x = 5*

*Note: An equation simply is a expression that has an equal sign. This means that as long as there is an equal sign, it counts as an equation.

(a\times b) = (a\times b) +(b -1) = c \\  \\ 3 \times 2 = (3\times 2) +(2-1) = 6 +1=7 \\  \\ 5 \times 4 = (5\times 4) +(4-1) = 20 +3=23 \\  \\ 7 \times 6 = (7\times 6) +(6-1) = 42 +5=47 \\  \\ 9 \times 8= (9\times 8) +(8-1) = 72 +7=79 \\  \\  \\  \\ 10 \times 9 = (10\times 9) +(9-1) = 90 +8=\boxed {\bf{98}}\\\sf {10\times 9 = \boxed{\bf {98}}}
