If it was reduced by 49 to 140 than obviously the original price was 189$
The solutions are 7, - 7, 2, - 7
Answer:
Step-by-step explanation:
1/5 + 1/5 = 2/5
1/7 + 1/7 = 2/7
1/3 + 1/3 = 2/3
There are an infinite number of these fractions. They must be 1 and 1 in the numerator, and the denominator must be relatively prime to 2. The examples I have picked are prime in the denominator, but the rule is not without many exceptions. For example
1/9 + 1/9 = 2/9
I don't think you can pick an even denominator because it will reduce when put with two. Oh wait 2/18 + 2/18 = 4/18 = 2/9 But these could be reduced before adding. Still, it might count. It depends on who is marking the question.
What about an odd and even denominator?
1/9 + 1/18 = 3/18 = 1/6 There must be something that works, but I can't come up with an example.
the surface area of the prism is 
.
<u>Step-by-step explanation:</u>
Here we have , A right rectangular prism has a length of 15 millimeters, width of 3 millimeters, and height of 4 millimeters. We need to find What is the surface area of the prism . Let's find out:
We know that surface area of the prism = 
. According to question we have following parameters as :
Putting these values to find area of prism we get:
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
Therefore , the surface area of the prism is .
