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%
Answer:
A. x = -7, B. x = -8, C. x = 9, D. x = 2, E. x = -3
Step-by-step explanation:
A. 4x= -28
Divide both sides by 4.
=
. x= -7
B. x- -6= -2 -> x+6= -2
Subtraction 6 to both sides.
x- +6-6= -2-6, x= -8
C. -x+= -9 -> x= 9
D. -3x+7=1
Subtraction 7 to both sides.
-3x+7-7 =1-7 , -3x=-6
Divide both sides by -3.
=
, x= 2
E. 25x+-11= -86 -> 25x-11= -86
Add 11 to both sides.
25x-11+11= -86+11, 25x= -75
Divide both sides by 25.
=
, x= -3
2. 2x+9= -15
Subtraction 9 to both sides.
2x+9-9= -15-9, 2x= -24
Divide both sides by 2.
=
, x= 12
I don't think there's an answer.
