A dinner set can be bought for $110000 cash or by a deposit of $37000 and 24 equal monthly installments of $4600 each. How much more will the dining set cost using the hire purchase method of payment?
The difference between the dining set cost using the hire purchase method of payment is $37400.
How to calculate the cost?It should be noted that when the hire purchase is used and there is a deposit of $37000 and 24 equal monthly installments of $4600 each.
The total amount will be:
= $37000 + ($4600 × 24)
= $37000 + $110400
= $147400
On the other hand, the dinner set can be bought for $110000 cash.
Therefore, the difference will be:
= Hire purchase - Cash.
= $147400 - $110000.
= $37400
Therefore, the difference between the dining set cost using the hire purchase method of payment is $37400.

Solve the simultaneous question x-2y=10 X=6y+2
Answer:
x = 32
y = 5
Step-by-step explanation:
2y=10
X=6y+2
Put both equations in the same format
x - 6y = 2
Manipulate the equations so that they have a common coefficient
6y = 30
Solve for one coefficient
(x - 6y = 2) + (6y = 30)
x + (-6y + 6y) = 2 + 30
x = 2 + 30
x = 32
Solve for the other coefficient
2y = 10
y = 5
x - 6y = 2
32 - 6y = 2
-6y = 2 - 32
-6y = -30
y = -30/-6
y = 5

The equation is
B) Solve your equation in part [A] for x.
Answer: x =
Answer:
A) 2 + 8x = -134
B) x = -17
Step-by-step explanation:
Note: I am assuming the question says use x as a variable, not z. Otherwise part B does not make sense
If we let variable x be the number then
8 times a number ==> 8x
2 and 8 times a number ==> 2 + 8x
2 and 8 times a number is -134 ==> 2 + 8x = -134
A) Equation form is 2 + 8x = -134
B) Equation is
2 + 8x = -134
Subtract 2 from both sides:
2 - 2 + 8x = -134 - 2
8x = -136
Divide both sides by 8 to give
8x/8 = -136/8
x = - 17

given g(x) = 2x/x-2, x≠2. find g¹³(8)
Answer:
8/3
Step-by-step explanation:
[tex]g^2 (x)=\frac{2\left(\frac{2x}{x-2} \right)}{\frac{2x}{x-2}-2} \\ \\ =\frac{4x}{2x-2(x-2)} \\ \\ =\frac{4x}{4} \\ \\ =x[/tex]

Step-by-step explanation:
How would you find the missing number in a mean sequence where you only know one number? (and also the mean of the known number and the missing number)
Step-by-step explanation:
The mean of a set of numbers is the average of those numbers. You can find the mean by adding the set of numbers and dividing by how many numbers are given. If you are given the mean and asked to find a missing number from the set, use a simple equation.
Add up the numbers you know. The problem states a mean of 58 with this set of numbers: 43, 57, 63, 52 and x. Assign the missing number a value of “x.” So add 43, 57, 63 and 52 to get 215.
Set up your equation by adding 215 plus “x” (the missing number), divided by 5, the number of values given. Set that side of the equation equal to the mean, 58. So, your equation would look like this: [tex] \frac{215+x}{5} = 58 [/tex]
Multiply each side by 5 since our goal is to get “x” by itself. This process cancels the 5 on the left side of the equation and gives you 290 on the right side (58 × 5). Now, your equation should look like this: [tex] 215+x=290 [/tex]
Subtract 215 from each side as you continue to work to get “x” alone. This cancels out the 215 on the left side of the equation and gives you 75 on the right side. Now, your equation should show that x = 75. Therefore, the missing number is 75.
Check the missing number by adding all the numbers together and dividing by 5.
[tex] \frac{43+57+63+52+75}{5} = \frac{290}{5} = 58 [/tex]

As per the question statement, we are required to determine the relation which has a domain of {-5, -3, 0) and a range of {1, 2, 3, 4, 5, 6, 7, 8).
To solve this question, we will use the trial-and-error method on the options provided. We have to find out possible (x, y) combination, where "x" belongs to the set of {(-5), (-3), 0} and "y" belongs to the set of {1, 2, 3, 4, 5, 6, 7, 8}, and match these combinations with the options.
The first option has x values from the set of {1, 2, 3, 4, 5, 6, 7, 8} and y values from the set of {(-5), (-3), 0}. Hence, it is not the correct answer.
The second option has x values from the set of {(-5), (-3), 0} and y values from the set of {1, 2, 3, 4, 5, 6, 7, 8}. Hence, it is one possible correct answer.
The third and fourth options have values out of the sets of {(-5), (-3), 0} and {1, 2, 3, 4, 5, 6, 7, 8}. Hence, they are not the correct answers.
Therefore, {(-5, 8), (-5, 2), (-3, 3), (-3, 1), (0, 4), (0, 5), (-5, 7), (-3, 6)} is the relation that has a domain of {(-5), (-3), 0} and a range of {1, 2, 3, 4, 5, 6, 7, 8}.

Answer:
The probability of rolling a 2 the next time that same die is rolled is 0.167.
Step-by-step explanation:
In this question it is given that there is rolling dice that is six sided and which is rolled for a 100 times and it was further observed that the probability of rolling a 2 was 12%.
Firstly, let us understand what is probability;
The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true.
Now,
Let us understand the concept of impossibility and certainty of an event;
An event's probability is a number between 0 and 1, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes certainty.
Further, In the above-mentioned condition, it is observed that the die has been rolled a 100 times;
The probability of getting X is only 12%.
Now,
In the condition where the die is rolled in for an extra time being a six sided, the probability of getting a 2 is 1/6.
=> 1/6
=> 0.167
Therefore, the probability of rolling a 2 the next time that same die is rolled is 0.167.
