Answer:

\frac{4 + 3y}{6y - 2}  =  \frac{ - 3}{5}  \\  \\   - 3(6y - 2) = 5(4 + 3y) \\  \\   - 18y + 6 = 20 + 15y \\  \\ 15y + 18y = 6 - 20 \\  \\ 33y =  - 14 \\  \\ y =  \frac{ - 14}{33} \\  \\ y =  - 0.42

I hope I helped you^_^

Plsss help it’s due today in an hour!!! (test grade)
Rudik [331]

Answer:

the area is 50.24 cm^{2}.

Step-by-step explanation:

The formula to find area of a circle is A=πr^{2}. A is area, and r is for radius. Since we have the diameter here, we just need to divide by 2 to find the radius. 8÷2=4, so there, the radius is 4. Now we need to square 4, and do 4x4, which equals 16. Now to multiply 16 by π, or 3.14. 16 x 3.14 = 50.24. The final answer is 50.24 cm^{2}. Hope this helped! :]

4x-1 + 2x-1 = 5x how do I solve this problem?
GREYUIT [131]

Answer: 2=x

Step-by-step explanation:

4x-1 + 2x-1 = 5x

First combine like terms together

4x-1 + 2x-1 is 4x+2x-1-1

4x+2x-1-1 =6x-2

4x-1 + 2x-1=6x-2

6x-2=5x

The oppisite of 6x is -6x so -6x on both sides of equation to keep it balanced

6x-6x-2=5x-6x

0-2=-1x

-2=-1x

Divide both sides of the equation by -1 since -1 is being multiplied by x and the oppisite of multiply is divide

-2/-1=-1x=-1

2=x

If you randomly choose two letters from the word "JANUARY ", find the probability that you choose letter J first and then A afte
miss Akunina [59]

Answer:

2.0%

Step-by-step explanation:

The probability of two events happening in the sequence is calculated by multiplying the probability of each event happening separately by one another. Since there are a total of 7 letters in this word then the probability of choosing one letter correctly is \frac{1}{7} . Since the first letter is replaced before choosing the second letter the probability remains the same. Therefore, the sequence would be the following...

\frac{1}{7} * \frac{1}{7} = 0.020164 or 2.0%

This is an independent scenario because it does not depend on any external factors and under these circumstances the percentage will remain the same.
