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

Step-by-step explanation:

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:

$6.60

Step-by-step explanation:

This is an incomplete question. I have however searched for the concluding parts and same attached as seen below.

First, we need to calculate the costs for both shoes rented by Dorian and Jack.

Member's cost for each shoe rentage is $2.95 , and since both rents the shoe at same cost, therefore,

Cost = $2.95 + $2.95 + $7.50

Cost = $13.40

To get the balance that Jack should receive, we will simply deduct the cost from the initial $20 member cost, hence;

Balance = $20 - $13.40

Balance = $6.60.

Therefore, the change that should be received by Jack is $6.60

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

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:

H. 20

Step-by-step explanation:

Answer: All of the above

Step-by-step explanation:

The formula for the standard error of the mean is:

σM =σ/√N

where,

σM = standard error of the mean

σ = standard deviation of sample

√N = square of sample size

As the sample size of a population rises, it should be noted that the standard error of the mean will decrease. This is due to the fact that when there's an increase in sample size, there'll be cluster of the sample mean around the population mean.

Also, the the standard error of the mean measures the variability of the sample mean from sample to sample and is never larger than the standard deviation of the population.

Therefore, the answer will be "all or the above".

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:

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:

7$

Step-by-step explanation:

1) 3x10=30 so 30 is how much money he needs

2)30-23=7 so 7 is how much he needs to borrow

Answer:

$7

Step-by-step explanation:

The reason is because three medium pepperoni pizzas cost $30, because you have to multiply $10x3 since each pizza cost $10. He already has $23 dollars in his pocket. You have to subtract his total value which is $23 from $30 to get $7.

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
