The amount invested in the account that yields 7% interest is $4000.
The amount invested in the account that yields 12% interest is $1000.
<h3>What are the linear equations that represent the question?</h3>
a + b = 5000 equation 1
0.07a + 0.12b = 400 equation 2
Where:
a = amount invested in the account that yields 7% interest.
b = amount invested in the account that yields 12% interest.
<h3>How much is invested at each rate?</h3>
Multiply equation 1 by 0.07
0.07a + 0.07b = 350 equation 3
Subtract equation 3 from equation 2
0.05b = 50
b = 50 / 0.05
b = 1000
Subtract 1000 from 5000: 5000 - 1000 = 4000

Answer:
1/18
Step-by-step explanation:
5/6 of an estate is to be divided among relatives
Let the total estate = 1
Remaining estate = 1 - 5/6
= 6-5/6
= 1/6 of the estate
Of the remaining a state 1/3 goes to the American cancer society
what fraction of the estate goes to the American Cancer Society
= 1/3 × 1/6
= 1/18
The fraction of the estate that goes to the American Cancer Society = 1/18
