Rupert buys a bicycle with a marked price of £ 12500.He gets a rebate of 10% on it. After getting
the rebate ,tax is charged at the rebate of 8%. Find the amount he will have to pay for the bicycle.
Answers
Answer:
£ 12,150
Step-by-step explanation:
Marked price of bicycle = £ 12500
Rebate = 10%
Amount of rebate = 12500*10/100 = £1250
Rebated price = 12500 - 1250 = £ 11,250
Tax = 8%
Amount of tax = 11250*8/100 = £ 900
Total amount paid for bicycle = Rebated price + amount of tax
= £ 11,250 + £ 900
= £ 12,150

X is the “number”, and twice of X is 2x. You get a sum from addition, so you would add 6 and 2x to get 2x + 6

ax+3=23 if a=0 plz help
Answers
Answer:
x = [tex]\frac{23}{a}[/tex]
Step-by-step explanation:
Given equation is,
ax + 3 = 23
To solve this equation for the value of x isolate the variable 'x' on the one side of the equation.
Step 1,
Subtract 3 from both the sides of the equation.
ax + 3 - 3 = 23 - 3
ax = 20
Step 2,
Divide the equation by a,
[tex]\frac{ax}{a}=\frac{23}{a}[/tex]
x = [tex]\frac{23}{a}[/tex]
Therefore, x = [tex]\frac{23}{a}[/tex] will be the answer.

what is the solution for x in 12x-4=5x+24
Answers
Answer:
x = 4Step-by-step explanation:
12x - 4 = 5x + 24
First subtract 5x from both sides
That's
12x - 5x - 4 = 5x - 5x + 24
7x - 4 = 24
Add 4 to both sides
That's
7x - 4 + 4 = 24 + 4
7x = 28
Divide both sides by 7
We have the final answer as
x = 4Hope this helps you
Answer:4
Step-by-step explanation:First, add 4 to both sides of the equation. Then subtract 5x from both sides. Finally, divide both sides by 7.

To solve this question, we need to understand the concept of Kelper's Third Law and how to use it.
we know that,
Kelper's Third Law:
Kelper's Third Law posits that the ratio between the square of the orbital period (T) as well as the average distance cube of a planet away from the Sun is constant for all planets circling the Sun.
T²/r³ = constant
Suppose, we make a reference to Earth, we have:
T_e²/r_e³ = T_j²/r_j³
Making the orbital period (T_j) of Jupiter as the subject, we have:
T_j = √T_e² * r_j³ /r_e³
where;
r_e = avg. distance from earth to sun = 1 au
so, calculating we get,
T_j = 11.9 years.

Under a dilation centered at the origin, the vertex, (−2, 4), of a polygon is moved to the point (4, −8) . What is the scale factor of the dilation?
Answers
Answer:
-2
Step-by-step explanation:
I took the quiz.
The scale factor of the dilation is -2.
How does dilation works?Dilation of a figure will leave its sides get scaled (multiplied) by same number. That number is called the scale factor of that dilation.
It's also called scaling of a figure, but due the involvement of coordinates, it involves a center of a dilation, which is like a pinned point which stays at same place after dilation.
It's like we enlarge or shorten the size of the figure (or keep it same, when scale factor = 1).
Given that Under a dilation centered at the origin, the vertex, (−2, 4), of a polygon is moved to the point (4, −8) .
Then the scale factor of the dilation
(-2k , 4k )= (4, −8)
Thus, -2k = 4
k = -2
Hence, the scale factor of the dilation is -2.
