How many liters of water must Sharon add to 2 liters of a sugar and water solution that is 36% sugar to create a solution that i
Dahasolnce [82]

The amount of sugar x in the starting solution contributes to a 36% concentration, so we have

\dfrac x2=0.36\implies x=0.64

units of sugar in the solution.

Into this solution, Sharon wants to pour y liters of water to obtain a smaller concentration of sugar in the overall solution:

\dfrac{0.64}{2+y}=0.12\implies\dfrac{16}3=2+y\implies y=\dfrac{10}3\approx3.33

So Sharon needs to add \dfrac{10}3 liters of water to the solution to get the desired concentration.

Use two unit multipliers to convert 135 square miles to square feet
Inessa [10]

You only need one of them:

               (135 mile²)  x  (5,280 feet/mile)²

           =  (135 mile²)  x  (27,878,400 feet²/mile²)

           =      (135  x  27,878,400)  mile² - feet² / mile²

           =          3,763,584,000  feet²

What does (d+3) represent in 4.5(d+3)=45
Scrat [10]

Answer:

(d + 3) would be 10

Step-by-step explanation:

<u>Step 1:  Distribute</u>

4.5(d + 3) = 45

(4.5 * d) + (4.5 * 3) = 45

4.5d + 13.5 = 45

<u>Step 2:  Subtract 13.5 from both sides</u>

4.5d + 13.5 - 13.5 = 45 - 13.5

4.5d = 31.5

<u>Step 3:  Divide both sides by 4.5</u>

\frac{4.5d}{4.5} = \frac{31.5}{4.5}

d = 7

<u>Step 4:  Determine what (d+3) is</u>

(d + 3)

(7 + 3)

10

Answer: (d + 3) would be 10
