A train leaves at 5.35 and arrives at 18.20 how long its journey . how long is the journey

First of all, try to understand the questions then try to make a pair of linear equations. After that make the coefficients of x or y equal in both RFD equations by multiplying them by suitable values then add or subtract them ,in such a way which will terminate any one of the variables. Then find the value of left variable. After that just put the value you have found just now In any of the equations and you'll really get the value of the second variable too.

Answer:

1,227

Step-by-step explanation:

3,000 divided by 3 is 1,000

600 divided by 3 is 200

80 divided by 3 is 26 r2

1 + r2 =3

and 3 divided by 3 is 1

1,000 + 200 + 26 + 1 = 1,227

Step-by-step explanation:

Hi!

Alright, so we're going to move all of the variables and constants to one side. Then, using the quadratic formula, we'll find the answer.

1. Move 12x-5 to the left side of the equation by

  a. Subtracting 12x from both sides

  b. adding 5 to both sides.

1: x^2+4x+20-12x+5

2. Group the common terms

  x^2+4x-12x+20+5 --> x^2-8x+25

3. Look at the problem. We can't factor this.

Explanation for why this isn't factorable (you can skip this)

(1) 25 is positive, so its two factors will both be either positive or negative. We're looking for a negative 8, so let's go with negative.

(2) Factors of 25: 1 & 25, 5 &5

Seeing the problem? Ya, none of the factors of 25 sum to eight. So, instead, we're going to use the quadratic formula.

4.  So, the quadratic formula: [tex]\frac{-b+-\sqrt{b^2-4ac} }{2a}[/tex]

Our equation is x^2-8x+25=0

a is the constant in front of the x^2

b is the constant in front of the x

c is the term without any x values

so, a=1, b=-8, and c= 25

Into equation:

[tex]\frac{8+-\sqrt{64-4(1)(25)} }{2a}[/tex]=[tex]\frac{8+-\sqrt{64-100} }{2}[/tex]=[tex]\frac{8+-\sqrt{-36} }{2}[/tex]

8/2 = 4

sqrt(-36) = 6i

6i/2 = 3i (remember, we still have the two in the denominator)

4 + (or -) 3i

Answer:

[tex]x=4+ 3\mathbf{i}[/tex]

[tex]x=4- 3\mathbf{i}[/tex]

Step-by-step explanation:

Solve:

[tex]x^2+4x+20=12x-5[/tex]

Move everything to the left side:

[tex]x^2+4x+20-12x+5=0[/tex]

Simplify:

[tex]x^2-8x+25=0[/tex]

Apply the solver formula:

[tex]\displaystyle x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

Where a=1, b=-8, c=25. Thus:

[tex]\displaystyle x=\frac{8\pm \sqrt{(-8)^2-4(1)(25)}}{2*1}[/tex]

[tex]\displaystyle x=\frac{8\pm \sqrt{64-100}}{2}[/tex]

[tex]\displaystyle x=\frac{8\pm \sqrt{-36}}{2}[/tex]

The solutions are complex numbers:

[tex]\displaystyle x=\frac{8\pm 6\mathbf{i}}{2}[/tex]

Simplifying:

[tex]x=4\pm 3\mathbf{i}[/tex]

Two solutions are found:

[tex]x=4+ 3\mathbf{i}[/tex]

[tex]x=4- 3\mathbf{i}[/tex]

Answer:

8 hours

Step-by-step explanation:

Given that:

Money spent by Jacqueline to rent a bicycle = $33.50

Per hour charges for the bicycle for renting the bicycle = $4

Processing fee charged for renting the bicycle = $1.50

To find:

The number of hours, [tex]x[/tex] for which Jacqueline rented the bicycle.

Solution:

Charges for 1 hour = $4

Charges for [tex]x[/tex] hours = $[tex]4x[/tex]

Processing fee = $1.50

Total fee charged for renting the bicycle is nothing but the sum of processing fee and the charges for [tex]x[/tex] hours charged by the bike rental facility.

Total money spent = Processing Fee + Charges for [tex]x[/tex] hours

Total money spent = 1.50 + 4[tex]x[/tex] = 33.50

[tex]\Rightarrow 4x = 32\\\Rightarrow x = \bold{8\ hours}[/tex]

So, Jacqueline rented the bicycle for 8 hours.

Answer:

50% off of the $62 for christmas wrapping is the better deal

Step-by-step explanation:

Let us compare the prices after the discount

25% off of the $40 for christmas wrapping paper

=25/100*40

=0.25*40

=$10

The new price is

40-10=$30

50% off of the $62 for christmas wrapping

50/100*62

0.5*62

=$31

The new price is

Answer:

The black-and white printer print can print 15 pages per minute.

Step-by-step explanation:

The given modeled equations are

3b + 5c = 70...(i)

6b + 9c = 135...(ii)

where b is the number of pages per minute of the black-and-white printer and c is the number of pages per minute of the color printer.

From equation (i), we have

[tex]3b=70-5c \\\\\Rightarrow b = \frac {70-5c}{3} \cdots(iii)[/tex]

Now, substitute the value of b in equation (ii), we have

[tex]6\times \frac {70-5c}{3}+9c=135 \\\\\Rightarrow 2(70-5c)+9c=135 \\\\\Rightarrow 140 - 10c+9c=135 \\\\\Rightarrow -c=135-140=-5 \\\\\Rightarrow c=5x^{2}[/tex]

By using equation (iii), we have

[tex]b = \frac {70-5\times5}{3}=\frac{45}{3}=15[/tex]

Hence, the black-and white printer print can print 15 pages per minute.

The black-and-white printer can print 15 pages per minute.

Given equations:

[tex]3b+5c=70[/tex]    ........(i)

[tex]6b+9c=135[/tex]  ........(ii)

Where b is the number of pages per minute of the black-and-white printer and c is the number of pages per minute of the color printer.

Solve the system of equations by substitution method

From (ii)

[tex]6b=135-9c\\b=\frac{135-9c}{6}[/tex]     ........(iii)

Put the value of b in (i), we get

[tex]3(\frac{135-9c}{6} )+5c=70\\\frac{135-9c}{2} +5c=70\\135-9c+10c=140\\c=5[/tex]

put c = 5 in (iii)

[tex]b=\frac{135-9(5)}{6} =\frac{90}{6} =15[/tex]

Therefore, The black-and-white printer can print 15 pages per minute.

Answer:

16,712.38

Step-by-step explanation:

Periodic interest rate 7.2%/12 = 0.6%

First find the monthly payment

M = $14,000 * 0.006(1 +0.006)^60/(1+0.006)^60-1 = 278.54

The total payment is $278.54 * 60= $16,712.38

Jesse's total payment amount for this loan is $16,712.38

Compound interest is a method of calculating the interest charge. In other words, it is the addition of interest on interest.

Compound Interest =P(1+r/n)^rt

We are given that Jesse took out a $14,000 car loan for 5 years at a 7.2% interest rate.

Periodic interest rate = 7.2%/12

= 0.6%

First we need to find the monthly payment

M = $14,000 x 0.006(1 +0.006)^60/(1+0.006)^60-1

M = 278.54

The total payment is

$278.54 x 60= $16,712.38

Hence, Jesse's total payment amount for this loan is $16,712.38

Answer:

She made a profit of 1,335 cedis

Step-by-step explanation:

Here, we want to calculate the profit made

Profit is selling price - cost price

Her cost price is 65 credits

For her selling price;

she sells 3 for 20 cedis

So the price she sold 210 will be;

(210 * 20)/3 = 1,400 cedis

So the profit made is;

1,400-65 = 1,335 cedis
