can you please explain how did you get that ?? :-)

Answer 5

ok this is what I did: I worked the problem and then I converted 97/7 into a decimal

Answer 6

great i want to see that "work"
how did you get 97/7 ?

Answer 7

ok here: Rewrite log(7z+3)=2 in exponential form using the definition of a logarithm. If x and b are positive real numbers and b≠1, then logb(x)=y is equivalent to by=x.
(10)2=7z+3
Remove parentheses around 10.
102=7z+3
Raise 10 to the power of 2 to get 100.
100=7z+3
Since z is on the right-hand side of the equation, switch the sides so it is on the left-hand side of the equation.
7z+3=100
Since 3 does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting 3 from both sides.
7z=−3+100
Add −3 and 100 to get 97.
7z=97

Answer 8

whichI subbed z into x

Answer 9

so its z=97 /7
