Answer:
Option d) is correct
ie, quotient property
Step-by-step explanation:
Given expression is log 618-log 66=log 63
Now we take log 618-log 66
log 618-log 66 = log 
[By using quotient property, log
]
= log 63
Therefore log 618- log 66= log 63
Option d) is correct
In the given expression we are using the quotient property
I like math so i think it's good for me
The answer is 7x = 6(x + 15)
x - Jim's rate
y - Pete's rate
<span>Jim completed half the floor in 7 hours: 7x = half of the floor
</span><span>Pete completed the other half of the floor in 6 hours: 6y = half of the floor
So: 7x = 6y
</span><span>Pete can lay 15 more tiles per hour than Jim: y = x + 15
</span>7x = 6y
y = x + 15
Substitute the second equation into the first one:
7x = 6(x + 15)
The base is 30.
Hopefully I got this correct, not 100%
