Answer:
0.137
Step-by-step explanation:
The computation is shown below:
Educated = 0.27
And, unemployed to educated is 0.043
Now probability of educated and unemployed is
= 0.043 × 0.27
= 0.1161
So, the educated would be
= 0.01161 ÷ 0.085
= 0.137
The answer would be 6(y+x).
Answer:
A
Step-by-step explanation:
First just simplify the terms.
y * 5 = 5y
y * 55 = 55y
55y + 5y = 60y
Answer:
x = 
Step-by-step explanation:
5x + 2(x + 1) = 4
5x + 2x + 2 = 4 (here we got rid of the parenthesis)
7x + 2 = 4 (here we summed both of our x values)
7x = 4 - 2 (here we took #2 to the other side of the equation)
7x = 2 (we subtracted 4 - 2)
x = 2 / 7
x =

Answer:
Explanation:
1. x represent the copybook while y represent the pen that is bought.
2. 2x + 3y = 9000 means that in order to buy 2 copybooks and 3 pen you have to pay 9000 LL.
3. Solve for the price of x and y
2x + 3y = 9000 (1)
4x + 2y = 8000 (2)
Multiply (1) by -2:
-2(2x + 3y = 9000)
4x + 2y = 8000
——————————
-4x - 6y = -18000
4x + 2y = 8000
—————————
-4y = -10000
y = -10000/-4
y = 2500
Substitute y value into (2):
4x + 2(2500) = 8000
4x + 5000 = 8000
4x = 3000
x = 3000/4
x = 750
Therefore, 1 copy book = 750LL and 1 pen = 2500 LL
