We first find out time taken to travel for just 1 km

2hrs is equivalent to 120 minutes

120 km  = 120 min

1 km  =  x        (where x is the time taken to travel 1 km).

we simplify the equation by cross - multiplying the equation , so:

120  × x = 1 × 120  → 120x = 120  → x  = 120/120 → x = 1

So  the car covers 1km  in 1 minute

For 300 km the car will take 300 × 1 minute = 300 minutes

we convert minutes to hours by dividing by 60 → 300 / 60 = 5

Therefore the car will take 5 hours to cover 300 km.

First you find the unit rate which is 60 km/ hour. Then You divide 300 by 60 to see how long it will take the car to travel 300 km which is 5
So It Will Take 5 Hours

The original price of an item is $130. The item is on a discount of 1/5 off the original price. You then pay a sales tax of 10%.
ahrayia [7]
Hello!

First, find 1/5 of $130, and then subtract that from the original price of the item, because it is a discount.

Divide the price of the item by 5.

130 ÷ 5 = 26

130 - 26 = 104

So, the price of the item (not including tax) is $104. Now, we must calculate the sales tax and then add that onto the price of the item, as tax is money collected by the government.

To calculate the tax, multiply the discounted price of the item by the percentage of tax, and then add it.

104 × 10% = 10.4

104 + 10.4 = 114.4

ANSWER:

The amount of money you paid fot the item is $114.4.

What is the slope of the line described by the equation y-1=3x
Alex777 [14]

Answer:

Hey there!

The line can be expressed into y intercept form, y=3x+1.

Thus, in y=mx+b form, m is the slope, and we see that 3 is the slope of the line.

Let me know if this helps :)
