Answer: He invest $2500 in account with rate of interest 5% and invest $3500 in account with 6% of interest so that the total interest earned is $335.
Step-by-step explanation:
Given: The rate of interest for account 1= 5%=0.05
The rate of interest for account 2= 6%=0.06
Let P be the Principal amount Keisha invested in the account with 5% interest .
Then the amount she will invest in account with 6% interest= 6000-P
Time = 1 year
The simple interest is given by:-

Simple interest for account 1=
Simple interest for account 2=
According to the question,
Total Interest =$335

So, he invest in account with 5% interest= $2500
He invest in account with 6 % interest=$6000-$2500=$3500
Answer:
6.28 km
Step-by-step explanation:
The formula for circumference is C = 2πr. Just plug in the radius. C = 2π2. 2 times 2 is 4. So, multiply 4π, which is 6.283185307 (rounded to the nearest billionths). Generally, you are supposed to round to the nearest hundredth. The 3 would round the 8 down, leaving 6.28. The unit used to measure the radius, so unless told otherwise by the problem, stick to km. This results in 6.28 km being your final answer.
(3x - 2y) / (z + 4)........x = 1, y = -2, z = 3
now we start subbing
((3(1) - 2(-2)) / (3 + 4).....simplify
(3 + 4) / (3 + 4) =
7/7 =
