Four times a number, subtracted from four, is twice the number. Find the number.
Answer:
[tex]\frac{2}{3}[/tex]
Step-by-step explanation:
let the number be n , then
4 - 4n = 2n ( add 4n to both sides )
4 = 6n ( divide both sides by 6 )
[tex]\frac{4}{6}[/tex] = n
The number is [tex]\frac{2}{3}[/tex]
Answer:
Let the number = x
4 - 4x= 2x
4 = 2x+4x
4 = 6x
x = 4/6
x = 2/3

A garage sells cars.
It offers a discount of 20% off the normal price for cash.
Dave pays £5200 cash for a car.
Calculate the normal price of the car.
Answer:
6,500
Step-by-step explanation:
Discount = 20%
Therefore the cost price is 100 - 20 = 80%
so,
£5,200 = 80%
To find the 100% ( the cost of the car before the discount), invert the fraction.
100/80 x 5200/1 = 6,500

Answer:
C
Step-by-step explanation:
Divide the Y values by the X values to check your answer
Answer:
C
Step-by-step explanation:
The question asks for a 0.3 constant of proportionality between 'x' and 'y'.
So, if you multiplied 0.3 to the number in 'x', you would get the number in 'y'.
By process of elimination, we can find that in A, 0.3 * 6 is not 2 and it's the same for all the other numbers in the table.
For B, 3*0.3 is not 1.8 and 0.3 multiplied by the other numbers in B do not match the number in y.
The only answer that matches is C, 4*0.3 is 1.2, 8*0.3 is 2.4, and 13*0.3 is 3.9.
So, the answer is C.

Write the equation of a line with a point at `(-3,2)` and has a slope of `\frac{1}{2}`.
Answer:
y = (1/2)x + 7/2
Step-by-step explanation:
y = ax + b (general form of a linear function)
a = 1/2 (slope)
y = (1/2)x + b
(-3, 2) is on the line, 2 = (1/2)*(-3) + b
2 = -3/2 + b
b = 2 + 3/2
b = 7/2
equation: y = (1/2)x + 7/2

I’m confused with this question, so I can’t find the median because there is repeating numbers so yeah
Answer:
60
Step-by-step explanation:
To find the mean, add all numbers together and divide by the amount of numbers.
Total of number = 660
Number of numbers = 11
660/11 = 60
Answer:
The median is 70.
Step-by-step explanation:
I believe you may have mixed up median with mode.
Here are the definitions of both:
Mode - The value that appears the most in a data set
Median - The middle number in a list of numbers ordered from least to greatest
To find the median of this data set, we must arrange the numbers from least to greatest!
20, 20, 30, 50, 60, 70, 70, 80, 80, 90, 90
Now we just have to figure out the middle number...which is 70!
20, 20, 30, 50, 60, 70, 70, 80, 80, 90, 90
I hope this helps! Let me know if you have any other questions :D
