Answer:
Option B. 9 ml.
Step-by-step explanation:
Recommended dose of a drug = 5 mg/kg body weight.
weight of the cat = 8 lb
1 lb = 0.4536 kg.
8 lb = 0.4536 × 8 = 3.6288 kg. ≈ 3.6 kg
A solution contains a concentration of 2 mg/ml
so recommended dose for 3.63 kg = 5mg × 3.6 = 18 mg
∵ 1 ml. contains a concentration = 2 mg
∴ for 18 mg concentration dose will be = 18/2 = 9 ml
9 ml of the solution should be given to a cat.
Option B. 9 ml.
The expressions equivalent to 5+(-3)(6x-5) is -18 x +20 , Option A is the correct answer.
The complete question is
Which expressions are equivalent to 5+(−3)(6x−5)
Choose all answers that apply:
A : -18x+20
B: 3x-3
C: None of the above
<h3>What is an Expression ?</h3>
An expression is a mathematical statement that has variables , constants and mathematical operators all simultaneously.
The expression given is
5+(-3)(6x-5)
By Distributive Property
a(b+c) =ab+ac
5 + (-3*6x) -(-3*5)
5 - 18x +15
-18 x +20
Therefore Option A is the correct answer.
