Answer: x = -16
Step-by-step explanation:
3x - 11 = -x - 75 then solve. see photo attached for work.
Answer:
She gets an increase of $750 each year so in the tenth year she would make $34,850
Step-by-step explanation:
The answer is actually cube A
Using proportions, it is found that the infusion rate is of 150 ml/hr.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, 50 ml are administered over 20 minutes. How much is administered over one hour = 60 minutes? The <em>rule of three</em> is:
50 ml - 20 min
x ml - 60 min
Applying cross multiplication:
x = 50(60)/20
x = 50(3)
x = 150.
The infusion rate is of 150 ml/hr.

Answer:
Step-by-step explanation:
Since the journey initially costs $2 (this will be our y-intercept), and the variable (x) is $1 for every additional kilometer. This can be modelled as...
y=1x+2
(i) if we want to know the cost of what 3.5 km would cost, we simply plug it into our equation...
y=1(3.5)+2
Answer: $5.5
(ii) For this question you can set the y value equal to 6 and plug in a random number for x until you get 6 on both sides. In this case...
6=1x+2
6=1(4)+2
The distance traveled if the fare was $6 is 4km
