Valentin [98]

Step-by-step explanation:

3 + \frac{9}{4} = \frac{9}{x+4} \\  \\  \therefore \: \frac{3 \times 4 + 9}{4} = \frac{9}{x+4}  \\  \\ \therefore \: \frac{12 + 9}{4} = \frac{9}{x+4}  \\  \\ \therefore \: \frac{21}{4} = \frac{9}{x+4} \\  \\ \therefore \:21(x + 4) = 36 \\  \\ \therefore \:21x + 84 = 36\\  \\ \therefore \:21x = 36 - 84\\  \\ \therefore \:21x = - 48\\  \\  \therefore \:x =  \frac{-48}{21} \\  \\ \therefore \:x =  \frac{-16}{7} \\  \\  \huge \red{ \boxed{ \therefore \:x = - 2 \frac{2}{7} }}\\  \\

Pls help me complete this

Answer: The number of times a yellow cube will be drawn is 390 times.

Step-by-step explanation: Like the last question with the blue cubes, set up a ratio.

Since it is still 240 times drawn and we need to figure out how many times a yellow cube will be drawn from 1200 times, the top number only changes.

78/240 = x/1200

Multiply 78 and 1200, which is 93,600.

Divide that by 93,600, which is 390.
