Answer:
The answer is (d) 30
Step-by-step explanation:
The LCD (lowest common denominator) of 5/6 is 5 * 6 = 30.
And 2/5 s 2 * 5 = 10
10 = 2×5
15 = 3×5
LCM = 2×3×5 = 30

Step-by-step explanation:
A. 4 km
B. 6 km
C. 8 km
D. 16 km
Given the average speed of Serena during her trainingand the time elapsed, the total distance that she ran is 16km.
Option D) 16km is the correct answer.
Speed is simply referred to as distance traveled per unit of time.
It is expressed as;
Speed = distance ÷ time
Hence,
Distance = Speed × time; d = r × t
Given the data in the question;
From the given formula;
d = r × t
We substitute our given values into the expression above.
d = 8km/hr × 2hr
d = 16km
Given the average speed of Serena during her trainingand the time elapsed, the total distance that she ran is 16km.
Option D) 16km is the correct answer.

The cost , in dollars, for 3 pounds of oranges is 1.8
Solution:
Given that Monica paid 3.20 for 2 pounds of apples and 2 pounds of oranges
Sarah paid 4.40 for 2 pounds of apples and 4 pounds of oranges.
Let the cost of orange per pound = x
Let the cost of apple per pound = y
Therefore, we can frame an equation as follows for Monica and Sarah:
In Monica’s case:
2x + 2y = 3.20
Hence x + y = 1.6 ---- eqn 1
In Sarah’s case:
4x + 2y = 4.40
Hence 2x + y = 2.2
y = 2.2 -2x – eqn 2
Substitute eqn 2 in eqn 1 we get,
x + 2.2 -2x = 1.6
-x = 1.6-2.2 = -0.6
x = 0.6
Substituting the value of “x” in eqn 2 we get the value of “y” as 1
Thus the cost of orange per pound is 0.6
Therefore, cost of 3 pounds of oranges = 3 × 0.6 = 1.8
