Step-by-step explanation:
19) Amount of oil in = amount of oil in final product
.025(x) + .09(40-x) = .055(40) (x = 2.5% amt 40 - x = 9% amt)
x = 21.54 L of 2.5 % then 9% = 18.46 L
Answer:

Answer: 50 x
Step-by-step explanation:
Answer:
y=2x - 4
Step-by-step explanation:
slope intercept is y = mx+b, where m is slope and b is y intercept.
subtract 2x from both sides of the equation
-y = 4 - 2x
multiply each term in -y = 4 - 2x by -1
(-y) . -1 = 4 . -1 + (-2x) . -1
y= 4. -1 + (-2x) . -1
simplify
y= -4 + 2x
Reorder
y= 2x - 4
