The answer you are looking for is 3x+15=5x-7. But, the answer is x=11.

Sure, I will help you. The answer you are looking for is x=11.

Solution/Explanation:

Write out the equation:

3(x+5)=5x-7

Using the Distributive Property on the LEFT SIDE,

3x+15=5x-7

Next, subtracting 3x from both sides,

3x-3x+15=5x-3x-7

15=2x-7, or 2x-7=15

2x-7=15

Now, adding seven to both sides,

2x-7+7=15+7

2x=22

Finally, dividing both sides by 2,

So, therefore the final answer is x=11. And, also, the next step would be written as 3x+15=5x-7, as stated above, preliminarily.

I hope this helped you find your answer. Enjoy your day, and take care!

12 yellow balls and 9 red balls are placed in an urn. Two balls are then drawn in succession without replacement. What is the pr
denis23 [38]

Answer:

\frac{9}{35}

Step-by-step explanation:

When the first draw is done there are 9 red balls in a sample size of 21. So there probability of drawing a red ball will be \frac{9}{21}

When the second draw is done, there will be 12 yellow balls in a sample size of 20 since the first ball will not have been replaced into the bag. So the chance of someone drawing the second ball in the second draw is \frac{12}{20}

The probability of them happening in this order is the product of both probabilities:

\frac{9}{21}  * \frac{12}{20}  = \frac{9}{35}

What is the 15th term of the sequence A(n) = 50 - 3(n-1) ?
Alexus [3.1K]

Answer:

A(15)=8

Step-by-step explanation:

Given that,

A(n)=50 - 3(n-1)

We need to find the 15th term of the sequence. Put n = 15 in the above sequence so that,

A(15)=50 - 3(15-1)\\\\A(15)=50-3(14)\\\\A(15)=50-42\\\\A(15)=8

So, the 15th term of the sequence is 8.
