ICE Princess25 [194]

Answer:

162 mL

Step-by-step explanation:

1.Convert all volumes to millilitres

(a) Chlorpheniramine

V = 100 mL

(b) Lidocaine

$V = \text{2 fl oz} \times \dfrac{\text{29.57 mL}}{\text{1 fl oz}} = \textbf{59 mL}$

(c) Banana flavouring

$V = \dfrac{1}{2}\text{ tsp} \times \dfrac{\text{4.928 mL}}{\text{1 tsp}} = \textbf{2.5 mL}$

2.Calculate the total volume

Chlorpheniramine = 100 mL

Lidocaine = 59

Banana flavouring = <u> 2.5 </u>

TOTAL = 162 mL

Which ordered pair is a solution to the system of equations?

enot [183]

Answer:

See below

Step-by-step explanation:

<u>Given system:</u>

2x - y = - 2
15x - 2y = - 7

<u>Solve by elimination, multiply the first equation by - 2 and add up the equations:</u>

-2(2x - y) + 15x - 2y = - 2(- 2) - 7
-4x + 2y + 15x - 2y = 4 - 7
11x = - 3
x = - 3/11

<u>Find the value of y:</u>

2( - 3/11) - y = - 2
-6/11 - y = - 2
y = 2 - 6/11
y = 1/11

<u>Solution is:</u>

( - 3/11, 1/11)

<em>None of the answer choices is matching this solution. Something must be wrong with the given equations.</em>
