Andrej [43]

Answer:

a = 6   b=  7

Step-by-step explanation:

4 (b-1) = 3b + 3       substitue for a

4b - 4 = 3b + 3       subtract 4b from both sides

-4 = 3b + 3 - 4b       =        -4 = -b + 3        combine 3b and (-4b)

-7 = -b      divide by -1 for both sides

7 = b


4a = 3 × 7 + 3       substitute for b

4a = 24             combine like terms

a = 6       divide by 4 on both sides


a = 7 -1

a = 6

You put $400 in an account. The account earns $18 simple interest in nine months. What is the annual interest rate
chubhunter [2.5K]

Answer:

6%

Step-by-step explanation:

Simple Interest formula:

S.I=P×R×T/100

where

S.I is simple interest

P is principle amount

R is Annual interest rate

T is time period

[usually represented as (number of months)/12]

so

$18=$400×R/100×9/12

simplify

$18=$3600R/1200

$18=$3R

so R=$18/$3

=6

Therefore,

The Annual Interest Rate is 6%
