Answer:

Mr. A initially paid approximately N8000 for the land.

Step-by-step explanation:

Step 1: Let's assume Mr. A initially purchased the land for a certain amount, which we'll call "x" in currency units.

Step 2: Mr. A sold the land to Mr. B at a profit of 10%. This means Mr. A sold the land for 110% of the amount he paid (1 + 10/100 = 1.10). Therefore, Mr. A received 1.10x currency units from Mr. B.

Step 3: Mr. B sold the land to Mr. C at a gain of 5%. This means Mr. B sold the land for 105% of the amount he paid (1 + 5/100 = 1.05). Therefore, Mr. B received 1.05 * (1.10x) currency units from Mr. C.

Step 4: According to the given information, Mr. C paid N1240 more for the land than Mr. A paid. This means the difference between what Mr. C paid and what Mr. A paid is N1240. So we have the equation: 1.05 * (1.10x) - x = N1240

Step 5: Simplifying the equation: 1.155x - x = N1240

Step 6: Solving for x: 0.155x = N1240

x = N1240 / 0.155

x ≈ N8000

Therefore, in conclusion, Mr. A initially paid approximately N8000 for the land.

Answer: 7x=30.5

Step-by-step explanation: If you were to answer this equation with the given information it would not be correct. 7(4.25)=29.75.  You need to go through BEDMAS to answer this.

You what you need to do is divide 30.5 by 7 to get the amount she needs to jog for a week, if you do that you get 4.37 miles each day to get to 30.5 in a week.

Answer: x=3.6; y=-2.5

Step-by-step explanation:

To solve this pair of equations, we can use elimination method.

5x+4y=8

10x-4y=46

Add both equations together to cancel out 4y.

15x=54               [divide both sides by 15]

x=3.6

Now that we know x, we can plug it back into any equation to find y.

5(3.6)+4y=8       [multiply]

18+4y=8             [subtract both sides by 18]

4y=-10                [divide both sides by 4]

y=-2.5

Now, we have x=3.6 and y=-2.5.

Answer:

EG = 34 FG = 25

Step-by-step explanation:

Answer:

EF = 34

FG = 25

Step-by-step explanation:

We are given that the length of line EG is 59. So we have to first solve for x in order to find the lengths of EF and FG:

(8x - 14) + (4x + 1) = 59

12x - 13 = 59

12x = 72

x = 6

EF:

Answer:

The volume of the space for each drawer is 6 feet^3.

Step-by-step explanation:

Solve for the volume of the entire dresser.

Formula for volume of a rectangle:

Volume (v) = Length (l) × width (w) × height (h)

v = 2 × 6 × 3

v = 12 × 3

v = 36

Now divide the volume by the number of drawers.

36 ÷ 6 = 6

Given :

B is between A and C

AB= x²-6x

BC= x²+20x

AC= 60-12x

B divide into 2 equal parts

AB and AC are equal

AC = AB +BC

60-12x = x²-6x + x²+20x

\(60= 2x^{2} -6x +20x +12x\)

\(60 = 2x^{2} -6x +32x\\\)

\(60= 2x^{2} +26x\)

\(30 = x^{2} +13x\\\\\)

\(x^{2} +13x -30 = 0\\x^{2} +15x-2x-30 =0\)

\(x(x+15) -2 (x+15) =0\)

\((x-2) (x+15) =0\\\)

x=2 , x=-15

x never be negative the x is 2

BC =  x²+20x

BC = 2*2 +20*2

BC = 4 +40

BC = 44

length of BC =44

The number in a radical needs to be square rooted to get placed out of it, so the square root of 20 can be split into the square root of 4 times the square root of 5, which can then be simplified to 2 rad 5, but there is a 2 outside of the radical, so then it becomes 4 rad 5, which is equivalent to 4 rad 5 so the first one is an answer.

Raising a number to the exponent of 1/2 is basically square rooting it.

For the second one, it's rad 6 - rad 5, which is not equal to 4 rad 5. That is not an answer.

For the third one, it's 3 times rad 5 + rad 5. That's 3rad5 + rad5. That's 4 rad 5, which is equal to 4 rad 5 at the top, so this is an answer.

For the fourth one, it's 4 times rad 5, so that's 4 rad 5, which is equal to 4 rad 5. That is an answer.

For the fifth one, 10 cannot be simplified to get out of the radical because it's only factors are 2 and 5, and neither of them are squares. That is not an answer.

For the sixth one, it's 3 times rad 5, so it's 3 rad 5. That is not an answer.

The answers are the first one, third one, and fourth one.

Car 1

Step-by-step explanation:

Answer: Car 1

Step-by-step explanation:

Notice that the speed of each car is the slope of the line that represents its average speed.

Since the graph of the speed of Car 1 passes through (0,0) and (4,256), we get that its slope is:

256/4 = 64

Therefore the average speed of Car 1 is 64 mi/h.

 Now, since the equation that represents the average speed of Car 2 is in slope-intercept form, we get that its slope is 55.

Therefore the average speed of Car 2 is 55 mi/h.

Answer: Car 1.

Answer:

Each Cow eats 7 kg and each Horse each 6 kg per day

Step-by-step explanation:

45C + 9H = 369

4H = 3C + 3

H = 3C/4 +3/4  

45C + 9(3/4C + 3/4) = 369

45C + 27/4C + 27/4 = 369  (Multiply both sides by 4)

45C (4) + 27C + 27(4) = 369(4)

180C +27C = 1476-27

207C=1449

C=1449/207=7  (substitute C=7 back into one of top equations)

4H = 3(7) +3

H = (21+3)/4 = 24/4 = 6

The kilogram of grass eaten by the cow is 7kg and the  kilogram of grass eaten by the horse is 6kg.

9h + 45c = 369 equation 1

4h = 3c + 3

4h - 3c = 3 equation 2

Where:

c = kg eaten by cows

h = kg eaten by horses

In order to determine the value of h, multiply equation 2 by 15

60h - 45c = 45 equation 3

Subtract equation 3 from equation 1

69h = 414

h = 6kg

Substitute for c in equation 2

4(6) - 3c = 3

24 - 3c = 3

21 = 3c

c = 7

The function y = e⁻ᵃ is a solution to the differential equation y' + y = 0 that satisfies the initial condition y(0) = 1.

Here we need to find a function that satisfies a differential equation and an initial condition.

The differential equation is given as

=> y' + y = 0.

To solve this differential equation, we need to find the general solution, which is a function that satisfies the equation for all values of t.

The characteristic equation for this equation is

=> m + 1 = 0,

which gives us m = -1 as the only solution.

This means that the general solution can be expressed as y = c1e⁻ᵃ, where c1 is an arbitrary constant.

Answer:

Step-by-step explanation:

Let the number of CD's = c

Let the number of tapes = t

Total  number of CD's and tapes = 9

c + t = 9   --------------- (i)

Cost of 'c' CD's = 7*c = 7c

Cost of 't' tapes = 6*t = 6t

Total cost = $ 68

7c + 6t = 58 -----------------(ii)

Multiply the first equation by (-6) and then add the equations.

(i)* (-6)       -6c - 6t = - 54

(ii)               7c + 6t =  58    {Now add. here t will be cancelled}

                   c         = 4

Number of CD's  = 4

Plugin c = 4 in equation (i)

4 + t = 9

The value of the car in 2000 is expected to be $3800, given a starting value of $7700 in 1990 and a decrease of $390 per year for 10 years.

To find the value of the car in each subsequent year, we can subtract $390 from the previous year's value. Let's calculate the value of the car for each year from 1990 to 2000.

Year 1990: $7700

Year 1991: $7700 - $390 = $7310

Year 1992: $7310 - $390 = $6920

Year 1993: $6920 - $390 = $6530

Year 1994: $6530 - $390 = $6140

Year 1995: $6140 - $390 = $5750

Year 1996: $5750 - $390 = $5360

Year 1997: $5360 - $390 = $4970

Year 1998: $4970 - $390 = $4580

Year 1999: $4580 - $390 = $4190

Year 2000: $4190 - $390 = $3800

Therefore, the value of the car is expected to be $3800 in the year 2000.
