If $26 represents the cost of the 5 used CDs, than your formula would be "26+4x" ,x being the amount of extra CDs you purchase.
The number CDs minus 5 is our x value, because the first 5 are the used CDs bundled into the $26 group.
26+4(6-5)
26+4(1)
26+4
30
6 CDs would cost $30
Answer:
Step-by-step explanation:
18/12 = 24/(x-2) Put the similar sides in the propertions.
I'm not too sure either.
5(5) + 3(5) = 40 and
5(2) + 3 (10) = 40
If you can't think of anything maybe that'll help
Answer:
P=2x+2y+14
Step-by-step explanation:
Perimeter (P)of a rectangle = 2( l+b)
where l is the length and b is the width of the rectangle .
Here, l= x+8
and, b= y-1
so, P = 2{(x+8)+(y-1)}
= 2( x+8+y-1)
= 2(x+y+7)
=2x+2y+14
