6% of a + 10% of (9000 - a) = 790
a = 2750
(9000 - a) = 6250
The amount invested at 6% is 2750.
The amount invested at 10% is 6250.
<h3>What is a percentage?</h3>
The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Total amount = $9000
Let the part invested for 6% = a
Let the part invested for 10% = (9000 - a)
Now,
6% of a + 10% of (9000 - a) = 790
6% = 6/100 = 0.06
10% = 0.1
0.06a + 0.1(9000 - a) = 790
0.06a + 900 - 0.1a = 790
-0.04a = 790 - 900
0.04a = 110
a = 110/0.04
a = 2750
Now,
9000 - a = 9000 - 2750 = 6250
Thus,
The amount invested at 6% is 2750.
The amount invested at 10% is 6250.

Answer:
700 miles per hour
Step-by-step explanation:
In miles per hour, the jet traveled 350/0.5 (30 minutes is half of an hour)
So the plane traveled (2*350)/(2*0.5) = 700/1
700 miles per 1 hour
Answer:N = 1
Step-by-step explanation:
6N-12=-18
You have to get 6N by itself, so take the -12 and make it a +12. That makes the 12 cancel out. So now you have 6N by itself. What you do one one side you have to do to the other side so take the positive 12 and add it to the -18. Now you have 6N=-6. Now divide, then you have your answer!!!
N=1
A. Negative ♡
Im pretty sure about this
Answer:
651 - ( -13 ) = 664
Step-by-step explanation:
As we know when there is a minus sign we hv to change the sign of the number after it .....
Therefore... ( -13 ) will become ( + 13 )
Then we can solve the equation...
651 - ( -13 ) = 651 + 13 = 664
Hope this helps....
