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.
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

What is the value of x (8x-8)° (7x+8)°
I'm going to assume they are the same angle.
Steps to solve:
(8x - 8) = (7x + 8)
~Add 8 to both sides
8x = 7x + 16
~Subtract 7x to both sides
x = 16

what steps could be used to solve the equation 1 + 3x = -x + 4.
Answer:
Combing like terms
Step-by-step explanation:
Answer: x = 3/4
Step-by-step explanation:
1+3x = -x+4
or, 1-4 = -x-3x
or, -3 = -4x
or, 4x = 3
or, x = 3/4
so, x = 3/4

One week, Wyatt earned $70.40 at his job when he worked for 4 hours. If he is paid the same hourly wage, how many hours would he have to work the next week to earn $281.60?
Answer: 8 hours
Step-by-step explanation: he gets 70.40$ to work for 4 hours so you'll have to multiply 4 by 70.40 to represent it's doubling to 8 and you'll get 281.60
70.40x4=281.60
so add this 4 to the other 4 it makes 8 because that's how much it would take to get there 4 steps up to really =8

Answer:
7 %
Step-by-step explanation:
Is means equals and of means multiply
7 = P * 100

ax+3=23 if a=0 plz help
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.
Using distributive property and combining like terms simplify the expression.

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?
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.
