A/2-b/3=1 solve for a, add b/3 to both sides
a/2=1+b/3 which is equal to
a/2=(3+b)/3 multiply both sides by 2
a=(6+2b)/3 now you can substitute this into 2a+3b giving you:
2(6+2b)/3 + 3b which is equal to
(12+4b+9b)/3
(13b+12)/3
Step 1:
Here we have -3 in subtraction on the left side, so when we take it to the right we apply opposite operation of subtraction that is addition.
Step 2:
Next we have 4 in multiplication on left side, so dividing right side by 4,
Step 3:
taking log on both sides
Step 4:
Dividing right side by 2,
x= ln (3.75) /2 = 0.66088
Answer : x = 0.66088..
Answer:
Step-by-step explanation:
Simple interest rate applies only to the principal amount deposited and not the compounded amount. The formula for simple interest is expressed as
I = PRT/100
Where
I is the interest.
P is the principal or initial amount deposited.
R is the interest rate.
T is the duration in years.
From the information given,
P = $300.00
R = 5 1/4% = 5.25%
T = 6 months = 0.5 years
Therefore,
I = (300×5.25× 0.5)/100 =787.5/100
I = 7.875
The balance in the account at the end of this time will be
300 + 7.875 = $307.875
