Answer:
The washer costs $723 and the dryer $241.
Step-by-step explanation:
Represent the cost of the washer by w and that of the dryer as d.
Then w = 3d.
Since w + d + $964, we get 3d + d = $964, or 4d = $964, or d = $241.
Three times that is $723.
A washer and dryer cost a total of $964 . The cost of the washer is three times the cost of the dryer. Find the cost of each item.
Answer: 96$
1) log7 (5*8)= log7(40)
2) log2(11) -log2(9)=log2(11/9)
3)2log9 2=log9(2^2)
Answer: 2m/s
The boat goes twice as fast down the river, which means it goes twice as slow up the river.
Because the river flows at 2m/s, I think the answer is 2m/s
