Answer:
Price of roses is proportional to the number of roses.
Step-by-step explanation:
Let the price of roses are proportional to the number of roses.
Equation representing this phenomenon will be,
P = k(R) ⇒ k = 
where 'P' = price of the roses
R = Number of roses
k = Proportionality constant
If we substitute the values of P and R and we get the same value of constant 'k', then the equation will be true.
For R = 3 and P = $9
k = 
k = 3
For R = 6 and R = 18
k = 
k = 3
K is same in both the conditions, therefore, Price of roses are proportional to the number of roses.
The average speed, in km/minute, of the train is 2.79 km/minute
<h3>Calculating average speed </h3>
From the question, we are to calculate the average speed in km/minute
From the given information,
Distance travelled = 503 km
Time taken = 3 hours = 3 × 60 minutes = 180 minutes
Using the average speed formula,
Average speed = Distance / Time
∴ Average speed of the train = 503 / 180
Average speed of the train = 2.79 km/minute
Hence, the average speed, in km/minute, of the train is 2.79 km/minute

Answer:
1/2 <3/4
Step-by-step explanation:
1/2 vs 3/4
We need a common denominator of 4
1/2*2/2 vs 3/4
2/4 vs 3/4
Since the denominators are the same, we compare the numerators
2 <3 so
2/4 < 3/4
1/2 <3/4
Answer:
Soil minerals are the foundation of the soil. They are made from rocks (parent material) that have been weathered and eroded naturally. Water, wind, temperature change, gravity, chemical interaction, live creatures, and pressure changes are all factors that aid in the breakdown of parent material.

<em>x = 1</em>
<em><u>Here is why:</u></em>
Add x to both sides.
Add 5 to both sides.
Divide.
x = 1
