Can someone help me with this?

Mathematics
1 answer:
nydimaria [60]4 years ago
4 0

Answer:

  1/18

Step-by-step explanation:

First of all, it works well to consolidate the minus signs:

  =-\dfrac{1}{2}+\dfrac{5}{9}

We can multiply the first fraction by 9/9 and the second one by 2/2 so they have a common denominator.

  =-\dfrac{1}{2}\cdot\dfrac{9}{9}+\dfrac{5}{9}\cdot\dfrac{2}{2}=\dfrac{(-1)(9)+(5)(2)}{(2)(9)}\\\\=\boxed{\dfrac{1}{18}}

aliina [53]

p→r

<h3>Law of syllogism</h3>

The law of syllogism, also known as transitivity reasoning, is a legitimate kind of deductive reasoning that adheres to a predetermined pattern. The transitive property of equality states that if a = b and b = c, then a = c. so we can conclude that The law of syllogism is almost  similar to the transitive property.

now if we want to define general case then we can say tha

a→b

and

b→c  => a→c

now according to statements given in the problem

p→q and q→r ⇒ p→r

which completes the syllogism.

hence ,  p→r is the required answer.

A person wishes to mix coffee worth ​$9 per lb with coffee worth ​$3 per lb
Sedaia [141]
To answer the question, let x be the number of pounds of coffee worth $9. Having said that, the number of pounds of coffee worth $3 is 120 - x. The equation relating the items before and after mixing is,
                      (x)($9) + (120 - x)($3) = (120)($5)
The value of x is 40. Therefore, the amount of coffee worth $9 and $3 to be used are 40 and 80 pounds, respectively.
