The difference between the weight of 3 gallons of liquid and a 5 pound brick is 19 pounds. Write an equation to represent this situation. What is the weight of 1 gallon of the liquid

3g - 5 = 19 ; 8 pounds

Step-by-step explanation:

Given that :

Difference between weight of 3 gallons of a liquid and a brick that weighs 5 pounds = 19 pounds.

Mathematically,

Let one gallon of the liquid = g

Hence,

(3 × g) - 5pounds = 19 pounds

3g - 5 = 19

The weight of one gallon(g) of the liquid equals :

From the expression above :

3g - 5 = 19

3g = 19 + 5

3g = 24

Divide both sides by 3

3g/3 = 24 /3

g = 8 pounds

Hence, weight of 1 gallon of the liquid is 8 pounds.

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
