John and Nadim do the math homework together. When they find 9 - (-8), they get different answers. John claims the difference is 17. Nadim claims the difference is -1. Who is correct?
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.

B. 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?
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

The lengths of the sides of a quadrilateral are 4 consecutive even integers. The perimeter of the quadrilateral is 36 inches. What is the length of the longest side?
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

The length of a rectangle is twice its width. The perimeter is 60 ft Find its area.
a) A=200 ft²
b) A= 10 ft²
c) A= 100 ft ²
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
At a sale, dresses were sold for $144 each. If the dresses originally cost $200 each, what percentage of its original price was a dress sold for?
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%

Help Idk what I did wrong show your work please
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

Tax rates are: no tax on the first £11000 of earnings earnings in excess of £11000 and up to £43000 taxed at a rate of 20% earnings in excess of £43000 and up to £150000 taxed at a rate of 40% Carys earned £45600 before tax how much tax did she pay in total?
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

Dorian and Jack decided to go bowling. They each need to rent shoes and 1 lane, and Jack is a member.If Jack pays for both of them with $20, what change should he receive?
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
which step is wrong pls help
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.
