photoshop1234 [79]

Consider the equation

$\dfrac{1}{4}x-5=\dfrac{x-20}{3}$ .

It is easy to see that x=20 is a solution of this equation, because when x=20:

$\dfrac{1}{4}x-5=\dfrac{1}{4}\cdot 20-5=5-5=0$ ,

$\dfrac{x-20}{3}=\dfrac{20-20}{3}=\dfrac{0}{3}=0$ .

Also this equation have:

1. the variable on both sides;

2. a fractional coefficient on the left side;

3. a fraction on the right side.

Answer:

Option E - None of these answers is reasonable.

Step-by-step explanation:

To find : Convert 17.42 m to customary units ?

Solution :

The customary units is defined as the measure length and distances in the customary system are inches, feet, yards, and miles.

The options belong to feet and inches.

We have to convert meter into inches, feet.

Meter into feet,

$1 \text{ feet} = 0.3048 \text{ meter}$

$1 \text{ meter} = \frac{1}{0.3048}\text{ feet}$

$17.42 \text{ meter} = \frac{17.42}{0.3048}\text{ feet}$

$17.42 \text{ meter} = \frac{174200}{3048}\text{ feet}$

$17.42 \text{ meter} =57 \frac{464}{3048}\text{ feet}$

$17.42 \text{ meter} =57 \frac{58}{381}\text{ feet}$

Now, Feet into inches

$1 \text{ feet} = 12\text{ inches}$

$\frac{58}{381} \text{ feet} = 12\times \frac{58}{381}\text{ inches}$

$\frac{58}{381} \text{ feet} =\frac{232}{381}\text{ inches}$

i.e. $17.42 \text{ meter} =57\text{ feet }\frac{232}{381}\text{ inches}$

or $17.42 \text{ meter} =57'\frac{232}{381}''$

None of these answers is reasonable.

Therefore, Option E is correct.

Ahmed, Walid and Faisal made $1446 profit from selling used books. If Ahmed to receive double amount of Faisal and Walid to rece

sukhopar [10]

Answer:

Faisal will receive $ 241
Ahmed will receive $ 482
Walid will receive $ 723.

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Profit Ahmed, Walid and Faisal made from selling used books = $ 1,446

Ahmed to receive double amount of Faisal

Walid to receive triple amount of Faisal

2. How much does each one receive?

Let x to represent the amount Faisal to receive
Let 2x to represent the amount Ahmed to receive (double amount of Faisal)
Let 3x to represent the amount Walid to receive (triple amount of Faisal)

Therefore, we have:

x + 2x + 3x = 1,446

6x = 1,446

x = 1,446/6

x = 241 ⇒ 2x = 482 ⇒ 3x = 723

Faisal will receive $ 241, Ahmed will receive $ 482, and Walid will receive $ 723.
