Answer:
3
Step-by-step explanation:
(5x -2y) / y
Let x = -4 and y = -4
(5*-4 - 2*-4) / -4
(-20 +8) / -4
-12/ -4
3
Answer:
n = -4/3 or n = 3
Step-by-step explanation:
Multiply by 6 to eliminate fractions, then put into standard form.
3n^2 -5n -12 = 0
3n^2 -9n +4n -12 = 0 . . . . . separate -5n into two terms to facilitate factoring
3n(n -3) +4(n -3) = 0 . . . . . factor pairs of terms
(3n +4)(n -3) = 0 . . . . . . . . . factor out the common factor
n = -4/3 or 3 . . . . . . . values that make the factors be zero
Answer:
First Method
First, he had M some unknown amount
Then, he had 2/3 M since he spent 1/3 M
Then, he spent 3/4 of the (2/3 M) so he had 1/4 of the ( 2/3M)
Then, he spent what was left $20 so $20 = 1/4 ( 2/3 M) now solve for M
You can check by doing each step and figuring how much was spent and how much was left.
Second Method
let us consider the left amount be Y and total now of M dollar be X
Y = amount of money Nartin has left
Y = X - ( 1/3 ) ( X ) - ( 3/4 ) ( X - 1/3 X ) - 20
Y = X - 1/3 X - 3/4 X + 3/12 X - 20
Y = X - 4/12 X - 9/12 X + 3/12 X - 20
Y = X - 10/12 X - 20
Y = X - 5/6 X - 20
Y = ( 1 / 6 ) ( X ) - 20
Hope this helps.
1 is the median
0000(1)2234
The median is the middle number
10000000 + 1 = 10000001
Duh
