Y=15x for the first and answer C for the second
Answer:
25 liters
Step-by-step explanation:
15x + 45(5) = 20(x + 5)
15x + 225 = 20x + 100
Simplify
125 = 5x
Divide both sides by 5
25 = x

Answer:
B. x = 5 and y = -13
Step-by-step explanation:
Subtract the constant on the left:
... (x +yi) = (9 -4i) -(4 +9i)
... = (9 -4 +i(-4-9))
... = 5 -13i
Matching real and imaginary parts, we see that ...
... x = 5, y = -13

Step-by-step explanation:</h3>
The mnemonic SOH CAH TOA reminds you of the definition of the tangent of an angle.
... Tan = Opposite/Adjacent
The side opposite angle C is AB. The side adjacent to angle C is BC. Then ...
... tan(C) = AB/BC = 18/80 = 0.225
