Elan Coil [88]

Answer:

Step-by-step explanation:

Alright, lets get started.

Suppose car was driven x miles in its 4 days trip.

Cost of a car rental is thirty dollar per day.

So, for 4 days, the car rental will be = $30*4=120$ $

For 1 mile, it adds fifteen cents,

So, for x miles, the cost will be = $0.15 x$ $

As per question, total rent is 180 $

Total rent will be = $120 + 0.15 x = 180$

Subtracting 120 in both sides

$0.15 x = 180-120=60$

$x=\frac{60}{0.15}$

$x=400$

It means car was driven 400 miles. : Answer

Hope it will help :)

How do i subtract mix number in fractions?

Galina-37 [17]

To convert mixed number fractions you can:

→ Convert them into improper fractions
→ Give the fractions common denominators
→ Subtract the two numerators, keeping the denominator
→ If necessary, simplify and convert your fraction back to a mixed number fraction

Example: 3 5/6 - 1 2/3

→ 23/6 - 5/3
→ 23/6 - 10/6
→ 13/6 = 2 1/6
∴ 3 5/6 - 1 2/3 = 13/6 OR 2 1/6
