Step-by-step explanation:

7x + 90 + 20 = 180

7x = 70

x = 10

5x + 2y = 90

50 + 2y = 90

2y = 40

Hey Gary :) Nice to see you around

For this question, we want to use logarithmic rules to write the expression as a single logarithm.
Using the rule log_{b} ( M^{k} ) = k *  log_{b} M , we can simplify 
3log_{b} q to log_{b} ( q^{3} ) . We can also simplify 6log_{b}(v) to log_{b}( v^{6}) .

So, we have log_{b} ( q^{3} ) + log_{b}( v^{6}).

Another logarithmic rule is:
log_{b}(M*N) =  log_{b} M +  log_{b} N&#10;

Using this rule, we can use the logs we have calculated and change them to:
log_{b}( q^{3}  v^{6})

This matches answer choice A.

Hope this helps! Feel free to contact me with any questions.
