There is a bag filled with 4 blue, 3 red and 5 green marbles.
Vsevolod [243]
<h2>The chances of receiving two greens are 5/31.</h2>

<em>Given a bag containing four blue, three red, and five green marbles, the total result is:</em>

<em>Total number of balls = 4 + 3 + 5 = 12</em>

<em>If green is chosen first, the chances of picking a green are 5/12.</em>

<em>The probability that the second stone is green is 4/11 if it is picked and not replaced (4 greens remaining)</em>

<em>The chance of earning two greens is 5/12 4/11.</em>

<em>The chance of getting two greens is 20/132.</em>

<em>The chance of earning two greens is 5/31.</em>

<h3><em>As a result, the chance of getting two greens is 5/31.</em></h3>

Solve this equation. Enter your answer in the box.<br> 13(y+7)=3(y−1).
Fofino [41]

★To Solve :

\rm\blue{13(y+7) = 3(y-1)}

⠀⠀⠀⠀⠀

★SOLUTION :

\rm\red\leadsto{13(y+7) = 3(y-1)}

\rm\red\leadsto{13\times{y}+13\times7= 3\times{y}-3\times1}

\rm\red\leadsto{13y+91=3y-3}

\rm\red\leadsto{13y-3y=-3-91}

\rm\red\leadsto{10y=-94}

\rm\red\leadsto{} y =\dfrac{   { \cancel{-94}}^{ \:-45 } }{   { \cancel{10}}^{ \: 5} }

\rm\red\leadsto{y=}\dfrac{-47}{5}

Making coconut cookies. The recipe calls for 420 g of coconut and 120 g of sugar. Only has 252 g of coconut. How much sugar must
geniusboy [140]

Answer: 72 grams.

Step-by-step explanation:

Let be "s" the amount of sugar in grams that  must be used for 252 grams of coconut to keep the same ratio of coconut to sugar.

Knowing that in the recipe for the coconut cookies, should be 420 grams of coconut and 120 grams of sugar, and you only have 252 grams of coconut, you can set up this proportion to find "s":

\frac{420grams}{120grams}=\frac{252grams}{s}

Now, you need to solve for "s":

\frac{420grams}{120grams}=\frac{252grams}{s}\\\\s(\frac{420grams}{120grams})=252grams\\\\s=(252grams)(\frac{120grams}{420grams})\\\\s=72grams
