As long as you keep the signs with the numbers the order doesn't matter. The cumulative property says that you can flip the numbers in any order and it will equal the same amount.
Answer:
$2000
Step-by-step explanation:
6,000 dollars is invested in two different accounts earning 3% and 5% interest.
Let x be the amount invested in account earning 3% interest
So, 6000-x is the amount invested in account earning 5% interest

So, Simple interest for account earning 3% interest


Simple interest for account earning 5% interest



Since we are given that the two accounts earned $220 in interest
So, 




So, 4000 was invested at 3%
(6000-x)=6000-4000=2000 was invested at 5%
Hence 2000 was invested at 5%
The answer is B because 140 plus 40 is 180
Answer:
2
Use the prime factorization:
7 * 5 * 1 = 35
7 * 5 * 2 = 70
If the cakes are circles,
3.14(4)2= 50.24
3.14(5)2= 78.5
78.5-50.24= 28.26
#1 is 28.26
