Answer:
Step-by-step explanation:
cos ( J ) =
=
=
The common denomenators of the denomenaotrs is 6(x+1)
times both the fraction by (6(x+1))/(6(x+1))
we get
(5(6)(x+1))/((x+1)+6)=(30(x+1))/(x+7)=(30x+30)/(x+7)
Answer:

Step-by-step explanation:

Determine the regular price (R)
From the question, we understand that:

So, we have:



<em>Hence, the regular price is $903.125</em>
Answer:
x=1 y =15
Step-by-step explanation:
hopefully correct
-5x-2y=13 (i)
3x-y=12
-y=12-3x
y=-12+3x (ii)
substitute ii into i
-5x-2(-12+3x)=13
-5x +24-6x=13
-11x=-11
x=1
substitute x into ii
y=-12+3(1)
y=15
.
. . x=1 and y =15
You are correct the answer is a:18
