Mr. osaka sprinkles 1.694 pints of dry, powdered plant food on his garden three times a year. in quarts, what's the total amount of plant food he uses in one year?

Mr. Osaka sprinkles 2.541 US dry quarts of plant food annually on his garden.

Step-by-step explanation:

1. Let's review all the information provided to answer the question correctly:

Amount of plant food Mr. Osaka sprinkles on his garden = 1.694 pints

Number of times Mr. Osaka sprinkles his garden annually = 3

2. In quarts, what's the total amount of plant food he uses in one year?

First of all, we need to calculate the total amount of plant food Mr. Osaka sprinkles on his garden annually, this way:

1.694 * 3 = 5.082 dry pints of plant food

Now, let's find the equivalency between US pints and US quarts

1 US dry pint = 0.5 US dry quart

Thus:

5.082 * 0.5 = 2.541 US dry quarts

Mr. Osaka sprinkles 2.541 US dry quarts of plant food annually on his garden.

starting with:    

5 + x - 12 = 2x - 7   

5 + x - 12 - x = 2x - 7 - x (subtract x from both sides)   

5 - 12 = x - 7 (combine and cancel x's from both sides)   

5 - 12 + 7 = x - 7 + 7 (add 7 to both sides)   

0 = x (add numbers together on both sides)       

so in order for the equation to be true, x must be 0.   

trying x = -0.5   

5 + x - 12 = 2x - 7 (original equation)   

5 + -0.5 - 12 = 2(-0.5) - 7 (plug in value of x)   

5 + -0.5 - 12 = -1 - 7 (did multiplication)   

-7.5 = -8 (did addition on both sides)       

since -7.5 is obviously not equal to -8, the value of -0.5 for x is wrong.   

trying x = 0   

5 + x - 12 = 2x - 7 (original equation)   

5 + 0 - 12 = 2(0) - 7 (plug in value of x)   

5 + 0 - 12 = 0 - 7 (did multiplication)   

-7 = -7 (did addition on both sides)       

since -7 equals -7, that demonstrates that the value of 0 for x is correct.   

trying x = 1   

5 + x - 12 = 2x - 7 (original equation)   

5 + 1 - 12 = 2(1) - 7 (plug in value of x)   

5 + 1 - 12 = 2 - 7 (did multiplication)   

-6 = -5 (did addition on both sides)       

since -6 is obviously not equal to -5, the value of 1 for x is wrong.
