A+ 2b = 10 2a + b =6
GenaCL600 [577]
First you can solve for b: Subtract a on both sides and get 2b=-a+10, then divide by 2 to get b by itself and get: b=-1/2a+5

Then you can plug in this equation for b in the other: This would give you: 2a+-1/2a+5=6. Then you can use that equation to solve for a and get: 1.5a+5=6, subtract 5, 1.5a=1, divide by 1.5, a=1/1.5

Then you can plug in the value of a to solve for b.

Answer:

3.1891

Step-by-step explanation:

Common logarithms are logarithms with base 10.

So the magnitude of Tallahassee: log_{10}(1.7*10^5)

And the magnitude of Bascom: log_{10}(1.1*10^2)

Difference between the two is: log_{10}(1.7*10^5)-log_{10}(1.1*10^2)

Type: "log(1.7*10^5)-log(1.1*10^2)" into calculator to get: 3.1891
