Answer:

Brent's speed is \frac{20}{3}\text{ mph}

Step-by-step explanation:

Given : The speed s that Brent can ride his bike if he rides \frac{3}{5} of an hour and travels 4 miles is given by the equation 4=\frac{3}{5}s

To find : What is Brent’s speed?      

Solution :

The distance is d=4 miles.

The time taken is t=\frac{3}{5} hour.

Solving the given equation to find s,

4=\frac{3}{5}s

s=\frac{4}{\frac{3}{5}}

s=\frac{20}{3}

Therefore, Brent's speed is \frac{20}{3}\text{ mph}

His speed is 6 2/3 mi/hr.

Our equation is 4 = 3/5s; to solve this, we want to divide both sides by 3/5:

4 ÷ 3/5 = (3/5s) ÷ 3/5
4/1 ÷ 3/5 = s
4/1 × 5/3 = s
20/3 = s
6 2/3 = s

ii. A machine is sold for 7,000/-. The gross loss is 20% of the cost. What are the cost and gross loss?
aleksley [76]

Given:

Selling price of a machine = 7000/-

Gross loss = 20%.

To find:

The cost and gross loss.

Solution:

Let x be the cost of machine.

According to the question,

x-20\%\text{ of }x=7000

x-\dfrac{20}{100}x=7000

x-0.2x=7000

0.8x=7000

Divide both sides by 0.8.

x=\dfrac{7000}{0.8}

x=8750

So, the cost of the machine is 8750/-.

Now,

\text{Gross Loss}=\text{Cost}-\text{Selling price}

\text{Gross Loss}=8750-7000

\text{Gross Loss}=1750

Therefore, the gross loss is 1750/-.
