Answer: Hello mate!

I guess here says:

125 = 5^x

and we want to express this equation in logaritmic form:

using the relation:

ln(a^b) = b*ln(a)

we can solve the previous equation for x as:

125 = 5^x

apply ln to both sides:

ln(125) = ln(5^x)

ln(125) = xln(5)

x = ln(125)/ln(5)

Ms.Wright opens a savings account with a deposit of $800. The bank will pay her 3% interest per year A.) how much interest will

Norma-Jean [14]

A) Ms.Wright receive $12 as interest at the end of 1/2 year.

B) Ms.Wright receive $24 as interest at the end of 1 year.

Step-by-step explanation:

The sum deposited in the bank = Principle = $800

The rate of simple interest = 3%

The time = 6 months = (6/12) years = 0.5 years

$\textrm{SIMPLE INTEREST} = \frac{P \times R \times t}{100} \\\implies SI = \frac{800 \times 3 \times 0.5}{100} = 12$

So, here simple interest = $12.

So Ms.Wright receive $12 as interest at the end of 1/2 year.

B) Now here Time = 1 year

so, Simple interest = $\frac{800 \times 3 \times1 }{100} = 24$

So Ms.Wright receive $24 as interest at the end of 1 year.

Can somebody help me What is 4(x-1)=6

avanturin [10]

4(x-1)=6 you start by dividing the whole equation by 4, so
x-1=6/4 simplify, x-1=3/2 then you add 1 to the whole equation
x=1 and 3/2 or x=5/2
