So which is equivilent
pemdas
(8-6x+12)
(20-6x)
multiply/distribute
1/4(20-6x)
5-6/4x=5-3/2x=-3/2x+5
the answer is D
so mean is equivilent to average
per minute means x feet for every one minute=xfeet/1miin=x/1
so just divide
-378/7=-54
mean change in altitude
-54 feet per minute
The final result is:
infinite solutions.
Since the solution has equal sides, there are infinite solutions.
Multiply 16*3 to get 48
48 * $28 = $1344
$1344 will be the cost to cover the counter top with tiles<span />
1+3x = 4x-9
add 9 to each side: 10+3x = 4x
subtract 3x from each side: 10 = x
7+2x = 3x
subtract 2x from each side: 7 = x
Answer:
This equals 58.10. The difference would be 24.90. Hope that helps :)
