Okay just find something the bottom and the top number can be divided by. Like the first one 9/18. They are bithe dividable by 9 so 9÷9=1. 18÷9=2. Now put one back over two. 1/2. So your answer is one half. This is to help you learn how to do it I hope it helps.
Answer: I believe it is 60-10=x because it says she purchased it with 60$ but recieved 10$ in change causing the amount we dont know to be a variable such as "x"
six times a number: 6(x)
The sum of 6(x) and 25: 6x + 25
6x + 25 is your expression.
hope this helps
log(4) + log(2) - log(5)
= log(2²) + log(2) - log(5)
= 2 log(2) + log(2) - log(5)
= 3 log(2) - log(5)
= log(2³) - log(5)
= log (2³/5)
= log (8/5)
= log (1.6) = 0.2041... (rounded)
