Answer:
64
Step-by-step explanation:
the different sum of money is 64
Answer: the fraction of her paycheck that she deposited in each account is 1/12
Step-by-step explanation:
Mrs. Pens spent 1/3 of her paycheck on her grooves and household goods and paid bills with 5/12 of the pay check. It means that the total amount that she spent is
1/3 + 5/12 = 9/12
The amount of money she has left would be
1 - 9/12 = 3/12
She then deposited the rest of the money equally in 3 accounts. Therefore, the fraction of her paycheck that she deposited in each account is
3/12 ÷ 3
= 3/12 × 1/3
= 1/12
The solution of the system of linear equation are (1, 7)
<h3>How to solve system of equation?</h3>
3a + 6b = 45
2a - 2b = -12
multiply equation(ii) by 3
Therefore,
3a + 6b = 45
6a - 6b = -36
9a = 9
a = 1
Hence,
2(1) - 2b = -12
2 - 2b = -12
-2b = -12 - 2
- 2b = - 14
b = -14 / -2
b = 7

Answer:
1/40
Step-by-step explanation:
A bag contains 5 blue, 3 red, and 8 green marbles
You have (5+3+8=16) marbles
P(red 1) = red/total = 3/16
You do not replace it
A bag contains 5 blue, 2 red, and 8 green marbles
You have (5+2+8=15) marbles
P(red 2nd) = red/total = 2/15
P(red 1, red 2) = P (red 1)* P (red 2) = 3/16 * 2/15
=1/40
3 times 8 is 24. 2 times 8 is 16. 1 times 8 is 8. all of them together is 48.
