4x+y=16 multiply both sides by -3 and will get
2x+3y=-2
-12x -3y = -48
2x +3y = -2
--------------------------
-10x 0 = -50
-10x = -50
x = -50/(-10) = 5
x = 5
4x+y=16
4*5+y=16
20+y=16
y = 16-20
y = -4
x = 5
y = - 4
hope helped
Answer/Step-by-step explanation:
<em><u>*An average person on Earth needs 8.5 hours of sleep each night*</u></em>
1. V - 5 = D
2. D ÷ 2 = S
3. S + 5 = V
<em><u /></em>
49 should be the correct answer.

14 and -18 would be less than or equal too when the -y makes them -14 and 18 it is still less than 19
Cost of goods = 1,500
Selling expense = 500
Total cost in selling = 1500 + 500 = 2000
Profit = Total Revenue - Total cost in selling = 3000 - 2000 = 1000
Profit = 1000
Hope this explains it.
