Try to rewrite the equation;
You know that 5 can be written as log3(3^5)
log3(3^5)=log3(x^2+18) <-- you can now cancel out log3
3^5=x^2+18
243-18=x^2
225=x^2
√225=x
+-15=x
You see that even if x is negative, the squared will always give a positive answer. Therefore, +15 and -15 are both possible answers.
Hope I helped :)
With percentage in the question, you divide the miles they drove by the total miles in the trip (and of course multiply it by 100).
Joe:
.3077 times 100= 31% (just rounded the percentage to the nearest whole number).
Adam:
.5385 times 100= 54%
Laura:
.1538 times 100= 15%
Tell me if this helps!!
