Don't be worried friend :)
-(y + 2) + 8 = 3

=> y + 2 = 5
=> y = 3
Answer:
558.036 lb
Step-by-step explanation:
Let x is the amount of the sea water to collect 125 lb of sea salt
As given: 64 lb/ft³ has 0.0035 dissolved salt by weight
So the formula to find out the amount of the sea water is:
64 lb/ft³ * 0.0035 *x ft³ = 125 lb
<=> x = 
= 558.036 lb
Hope it will find you well.
Answer:
The y intercept is (0,-8)
Step-by-step explanation:
To find the y intercept, set x = 0 and solve for y
-4x -2y = 16
-4(0) -2y =16
-2y = 16
Divide by -2
-2y/-2 = 16/-2
y = -8
The y intercept is (0,-8)
A + b = 15 ..... eq 1
a – b = 12 ...... eq 2
So a = 15 – b
Substitute in eq 2 :
15 – b – b = 12
15 – 2b = 12
–2b = 12 – 15
b = 1.5
So a = 15 – 3/2 = 13.5
4ab = 4 x 13.5 x 1.5 = 81
