The sum of two numbers is 79. Three times the first number added to 5 times the second number is 283. What are the two numbers?
Karolina [17]

Answer:

<u><em>The two numbers are 56 and 23.</em></u>

Step-by-step explanation:

Let the two numbers be A and B.

We are told that:

A+B = 79, and

2)  3A + 5B = 283

Rearrange the first expression to isolate A:

A = 79-B

Now use this value of B in the second expression:

3A + 5B = 283

3(79-B) + 5B = 283

237-3B + 5B = 283

2B = 46

B = 23

If B=23, we can find A from (1):  

A+B = 79

A+23 = 79

A = 56

<u>CHECK:</u>

Does A+B = 79?

56 + 23 = 79?  <u><em>YES</em></u>

Does 3A + 5B = 283?

  3(56) + 5(23) = 283?

 168 + 115 = 283?  <u><em>YES</em></u>

Solve for x: <br> 2700=300•2^10x<br><br> Check all that apply.Options are in image above
Genrish500 [490]

Answer:

B and C

Step-by-step explanation:

300  \times  {2}^{10x}  = 2700 \\  {2}^{10x}  =  \frac{2700}{300}  =  \frac{27}{3}  = 9 \\  {2}^{10x}  = 9 \\  log( {2}^{10x} )  =  log(9)  \\ 10x \times  log(2)  =  log(9)  \\ (10 log(2) )x =  log(9)  \\ x =  \frac{ log(9) }{10 \times  log(2) }

However, if you replace log with ln you can easily reach to the following solution as well.

x =  \frac{ ln(9) }{10  \times   ln(2) }
