The price of 10 citrons and 7 fragrant wood apples is 55 units. The price of 7 citrons and 10 fragrant wood apples is 64 units.

a_sh-v [17]

Price of one citron = 5 units

Price of one fragrant = 5/7 units = 0.71 units

Further explanation:

Let x be the price of one citron and

y be the price of one fragrant

Then according to given statement

10x+7y = 55 Eqn 1

7x+10y = 64 Eqn 2

Multiplying equation 1 by 7

$7(10x+7y) = 7(55)\\70x+49y=385$

This will be equation 3.

Multiplying equation 2 by 10

$10(7x+10y) = 10(64)\\70x+100y=640$

This will be equation 4.

Subtracting equation 3 from equation 4

$70x+100y - (70x+49y) = 640-385\\70x+100y-70y-49y = 255\\51y = 255\\\frac{51x}{51} = \frac{255}{51}\\x = 5\\Putting\ x=5\ in\ equation\ 1\\10(5)+7y = 55\\50+7y = 55\\7y = 55-50\\7y = 5\\\frac{7y}{7} =\frac{5}{7}$

So,

Price of one citron = 5 units

Price of one fragrant = 5/7 units = 0.71 units

Look at the picture! Express the following set in set-builder notation ?

Alex

Answer:

A. E={ $x|x\in N$ and $x$ is a multiple of 8}

Step-by-step explanation:

Let $x$ represent the set of natural numbers. Then we can write;

$x\in N$ .

The set of all natural numbers that are multiples of 8 is then written as;

$x\in N$ and $x$ is a multiple of 8.

E is the set of natural numbers that are multiples of 8 can then be written in set builder notation as;

E={ $x|x\in N$ and $x$ is a multiple of 8}

The correct choice is A
