The diameter of a circular rug is 5.6 feet. What is the radius?

Answer:

$168.75

Step-by-step explanation:

if it's narked down by 20% then $135 is 80% of the original price

80 = 135

100 = x

80x = 100×135

x = $168.75

A bike is on sale for $135. The original price of bike is 135

Solution:

Given that bike is on sale for $ 135

The mark down price is 20 %

We need to find the original price of the bike

Hence we can say that,

Selling price of bike = 135

Mark down price = 20%

Original price of bike = ?

The cost price is given as:

By substituting the values we get,

Hence the original price of bike is $ 168.75

Let me explain like this .Suppose There are 40 people gathered somewhere for attending an event.Each Person has to be given 2 sweets for their arrival or for showing their presence in the event. Now 40 other woman joined them..Instead of getting two sweets each of them got one sweet.

Solution:   2 sweets × 40 people = 1 sweet × 80 people = 80  

2nd Way:

There are 40 rooms in a building.In  Each room we have to fix two bulbs. So How many bulbs are there in the building.

Solution →→→2 bulbs × 40 room = 80 bulbs

Diagram is depicted below for two parts.

1/4(8-4p) + 2p = 12

Use distributive property by multiplying 1/4 by each term inside parentheses:

2 - p + 2p =12

Combine like terms:

2 + p = 12

Subtract 2 from both sides:

P = 10

P is equal to 10

How to get your answer:

So 1/4(8-4p) + 2p = 12

First you need to distributive by multiplying 1/4 to each term like this:

2 - p + 2p =12

Then you have to combine to terms just as I did below:

2 + p = 12

Then you need to subtract 2 from both sides to get 10 so:

P = 10
