Find the number which when divided by 4 and increased by 12 is the same as when it is divided by 3 and decreased by 5

MatroZZZ [7]

Step-by-step explanation:

Let's make the number we're finding to be $a$ . So, it says that it will be divided by 4 and then added by 12 if we want this in algebraic expression it will be $\frac{a}{4} +12\\$ . It's also telling us that that expression is the same thing as our number divided by 3 and subtracted by 5. If we want an expression out of it it well be $\frac{a}{3} -5\\$ . Since they are the same, we have the equation below.

$\frac{a}{4} +12 = \frac{a}{3} -5\\$

All we have to do now is to find $a$ .

$\frac{a}{4} +12 = \frac{a}{3} -5 \\ \frac{a +48}{4} = \frac{a -15}{3} \\ (3)(a +48) = (a - 15)(4) \\ 3a +144 = 4a -60 \\ (60 -3a) + 3a +144 = 4a -60 +(60 -3a) \\ a = 204$

<h3>Answer:</h3>

Our number must be $204$ . I think

If gasoline costs 1.50 euros per liter it will cost how much to drive 220 kilometers

jok3333 [9.3K]

Answer:

$11.79\ euros$

Step-by-step explanation:

<u><em>The complete question is</em></u>

Suppose that a new fuel-efficient European car travels an average of 28 kilometers on 1 liter of gasoline. If gasoline costs 1.50 euros per liter, how much will it cost to drive 220 kilometers ?

step 1

using proportion

Find out the number of liters of gasoline needed for 220 kilometers

so

$\frac{28}{1}\ \frac{Km}{L}=\frac{220}{x}\ \frac{Km}{L}\\\\x=220/28\\\\x=7.86\ L$

step 2

Find the cost to drive 220 kilometers

Multiply the cost of one liter of gasoline by the total liters of gasoline needed to travel 220 Km

so

$1.50(7.86)=11.79\ euros$
