Answer:
(7, 2 )
Step-by-step explanation:
Given the 2 equations
3x - 2y = 17 → (1)
x - 3y = 1 → (2)
Rearrange (2) expressing x in terms of y by adding 3y to both sides
x = 1 + 3y → (3)
Substitute x = 1 + 3y in (1)
3(1 + 3y) - 2y = 17 ← distribute and simplify left side
3 + 9y - 2y = 17
3 + 7y = 17 ( subtract 3 from both sides )
7y = 14 ( divide both sides by 7 )
y = 2
Substitute y = 2 into (3) for corresponding value of x
x = 1 + 3(2) = 1 + 6 = 7
Solution is (7, 2 )
1. You have the following information:
-The annual interest rate <span>is 7.2%.
- The </span><span>simple interest is calculated quarterly.
2. Then, to solve this exercise and calculate the </span><span>periodic interest rate of Marta's Account, you only have to divide the annual interest rate (7.2%) by 1/4 year. So, you have:
</span>
=(7.2%)(1/4)
=(7.2%)/4
=1.8%
<span>What is the periodic interest rate of Marta's Account?
The answer is: </span>1.8%
<span>w= 33.75, the weight of the larger sphere
</span>
