A racehorse that wins the 3200 meter Cup in a time of 200 seconds. What is the racehorse's average speed?

Answer: x = 10

Step-by-step explanation:

first Add 20 to both sides.

4x = x + 10 + 20

Then Simplify x + 10 + 20 to x + 30

4x = x + 30

Then u subtract x from both sides

4x - x = 30

Simplify 4x - x to 3x

3x = 30

Then u divide both sides by three

x = 30/3

Then u last simplify 30/3 to 10

x = 10

Answer:

x = 10

Step-by-step explanation:

first Add 20 to both sides.

4x = x + 10 + 20

Then Simplify x + 10 + 20 to x + 30

4x = x + 30

Then you subtract x from both sides

4x - x = 30

Simplify 4x - x to 3x

3x = 30

Then you divide both sides by three

x = 30/3

Then you last simplify 30/3 to 10

x = 10

Answer:

GH¢60

Step-by-step explanation:

Alex puts 1/4 1of his money in savings and uses 1/( 2) of the remaining money to pay back her sister. If she has GH¢15 left, how much did she have at first?

Let the Total amount of Alex money = 1

We are told that she has GH¢15 left,

Hence, we find the fraction of the money she has left

1 - (1/4 + 1/2)

1 - 3/4

= 1/4

The fraction of the amount she left = 1/4

Let x represent the total amount of money that Alex had

1/4 × x = GH¢15

x / 4 = GH¢15

Cross Multiply

x = 4 × GH¢15

x = GH¢60

Therefore, Alex had GH¢60 at first

Answer: x=-10

Step-by-step explanation:

3(-4+x)=-42

Distribute

-12+3x=-42

Bring -12 to the other side (switches signs)

3x=-30

Divide 3 from both sides

x=-10

just replace all the ms in the equation with -5

(-5^2) -8 x -5 - 6

25 + 40 - 6 = 59

Answer:

the second step and third step

Step-by-step explanation:

in the second step, you are supposed to move 5x to the left side

in the process of this, 5x should turn negative, and you should be subtracting it from 7x, not adding it.

so the +5x should be -5x

in the third step you should divide, but when you divide 6 by 12, you should get 0.5, not 2.

Answer:

She paid tax of £18240

Step-by-step explanation:

We are told that Carys earned £45600 before tax.

Now, from the question, the tax rate that applies is 40%. This is because she earned £45600 and we are told that earnings in excess of £43000 and up to £150000 taxed at a rate of 40%.

Thus;

Tax payable = 40% × 45600

Tax payable = £18240

Answer:

72%

Step-by-step explanation:

Percentage of  original price = (Selling Price/Cost Price) x 100%

                                                = ($144/200) x 100%

                                                = ($0.72) x 100%

                                                = 72%

Answer:

John is correct

Step-by-step explanation:

The rule in mathematics states that

- × + = -

+ × + = +

- × - = +

Hence, for the homework,

9 - (- 8) = x

9 + 8 = 17

Therefore, John is correct and Nadim is incorrect.

Answer:

Length of longest side is 10.5 inches

Step-by-step explanation:

Let the shortest side of the quadrilateral be x inches

The length of the consecutive sides will be;

x , x + 1 , x + 2 and x + 3 inches

By adding all

together, we get the perimeter of the quadrilateral

so;

x + x + 1 + x + 2 + x + 3 = 36

4x + 6 = 36

4x = 36-6

4x = 30

x = 30/4

x = 7.5 inches

The longest side is x + 3 = 7.5 + 3 = 10.5 inches

Step-by-step explanation:

Answer:

A=200 ft²

Step-by-step explanation:

let the Length be L and the Width be W

We know that Perimeter = Length + Length + Width + Width

or,

Perimeter = 2(L + W)  

given that Perimeter = 60 ft,

60 = 2(L+W)    (divide both sides by 2)

60/2 = (L+W)

L + W = 30 ---------------------eq 1

we are further given that the length is twice the width, or,

L = 2W ---------------------- eq 2

substituting eq2 into eq 1,

L + W = 30

(2W) + W = 30

3W = 30

W = 10  (substitute this into eq 2)

L = 2W

L = 2(10)

L = 20

Area = Length x Width

= 20 x 10

= 200 ft²
