Answer: Hello mate!
you put every number twice, I will consider that in this problem we have:
225 gallons of water initial with 5 pounds of sugar. then each minute you add 20 gallons of water and 4 pounds of sugar.
the concentration is defined as pounds of sugar divided by the gallons of water. The gallons of water are 225 initially and 20 per minute, this is written as 225 + 20tt, where t is the minutes. The pounds of sugar is 5 + 4 per minute, then this can be written as 5 + 4t
this is the equation that describes the concentration in pounder per gallon after t minutes.
She made her mistake at the first step. To simplify a radical, you would find two numbers that multiply by each other to get your original number (under the radical)
and have one of the number be a perfect square.
Her reasoning is wrong because 10*10 is not

. Had she been correct, her answer should have been able to be squared to equal

In other words, she should have done

(We used 25 because 25 is a perfect square, 5*5=25).

Answer:
Step-by-step explanation:
13.75+(-11.25)=13.75-11.25
13-11=2
0.75-0.25=.50
2.50
