Answer:

12 weeks

Step-by-step explanation:

Josiah and kiri are each saving money josiah starts with 100$ in savings accound and adds 5$ per week . Kiri with 40$ in her savings account adds 10$ each week after how weeks Josiah and kiri will have the same amount of money in their savings account

Josiah:

100 + 5w

Kiri:

40 + 10w

Where,

w = number of weeks

After how weeks Josiah and kiri will have the same amount of money in their savings account

Equate the savings of the both of them

100 + 5w = 40 + 10w

100 - 40 = 10w - 5w

60 = 5w

w = 60/5

= 12

w = 12 weeks

Josiah and kiri will have the same amount of money in their savings account after 12 weeks

5700 is compounded semiannually at a rate of 15% for 12 years
Rama09 [41]

Answer:

$32,335.38

Step-by-step explanation:

You are going to want to use the compound interest formula, which is shown below.

P(1+\frac{r}{n} )^{nt}

<em>P = initial balance </em>

<em>r = interest rate </em>

<em>n = number of times compounded annually </em>

<em>t = time</em>

<em />

Now lets plug in the values into the equation:

5,700(1+\frac{.15}{2})^{12(2)} = 32,335.38

Your answer is $32,335.38

How can properties of operations help to generate equivalent expressions that can be used in solving problems ?
svet-max [94.6K]
I’m not the best at math, but ⬇️

For example, apply the distributive property to the expression 3(2 + x) to produce the equivalent expression 6 + 3x; apply the distributive property to the expression 24x + 18y to produce the equivalent expression 6 (4x + 3y); apply properties of operations to y + y + y to produce the equivalent expression 3y
