Answer:
x - y = 5
x + y = 23
x = 14, y = 9
Step-by-step explanation:
Make x subject:
x = 5 + y
Substitute c by (5 + y) :
( 5 + y) + y = 23
2y = 18
y = 9
Substitute y (9):
x = 5 + 9
x = 14
Answer:
A. p = $17.95n - $1,250.00
Step-by-step explanation:
Profit (p) = net revenue - expenditure
Net revenue = charge for transfer of n videos - expense for n blank DVD
charge per video transfer = $20.40
charge for n video transfer = $20.40 × n = $20.40n
expense per blank DVD = $2.45
expense for n blank DVD = $2.45 × n = $2.45n
Net revenue = $20.40n - $2.45n = $17.95n
expenditure = $1,250.00
Therefore, p = $17.95n - $1,250.00
Step-by-step explanation:
g) 6g=54
g=54/6
g=9
h) 7h=73-10
h=63/7
h=9
I) 8x-32=48
8x=48-32
x=16/8
x=2
j) 63=27+9j
63-27=9j
36/9=j
4=j
k) 101-61=4x
40/4=x
20=x
l)46=8+x-5
46=3+x
46-3=x
43=x
Hope this helps you
have a nice day
