let sonia has the (x)
Sandeep would have twice as much as Sonia so (2x)
together they'd have 150.
so, x+2x=150
solve for X
3x=150
X=150/3
So x=50 is what Sonia has,
and Sandeep would have 2(50) =100
Therefore the reminder is 3 when 5n is divided by 7.
Step-by-step explanation:
we know that
Dividend = quotient × Divisor +Reminder
⇔ n = Q(n) × 7 + 2 [ let Q(n) is quotient]
multiplying by 5 both sides
5n = 5 Q(n) ×7 + 2×5
⇔5n = 5 Q(n) ×7 +10
⇔5n= 5 Q(n) ×7 +7 +3
⇔ 5n = (5Q(n) +1) × 7 +3
Therefore the reminder is 3 when 5n is divided by 7.

Question is Incomplete, Complete question is given below.
Consider a model of a train locomotive that has a similarity transformation map of x arrow right 48x from the model to the actual locomotive when answering the question.
If the diameter of the front wheels on the locomotive is 4 feet, what is the diameter of the front wheels on the model? Express the answer in inches.
Answer:
The diameter of front wheel on the model is 1 inch.
Step-by-step explanation:
Given:
Let diameter of the front wheel on the model be 'x'.
Actual diameter of front wheel = 4 feet
Now given that ratio model to actual = 
Now we can say that ratio model to actual is equal to ratio of model diameter of front wheel to actual diameter of front wheel.
framing in equation form we get;

Now we know that;

Hence The diameter of front wheel on the model is 1 inch.
