Answer:

see below

Step-by-step explanation:

The way the problem is worded, we expect "n" to represent the year number we're at the beginning of. That is the initial balance is that when n=1, and the balance at the beginning of year 5 (after interest accrues for 4 years) is the value of obtained when n=5.

After compounding interest for 4 years, the balance will be ...

500·1.04^4 = 584.93

if three bakers can prepare 15 cakes in 60 minutes, how long will it take six bakers working at the same rate to prepare 20 cak

ella [17]

-- 3 bakers produce 15 cakes in 60 minutes.

-- Each baker produces 15/3 = 5 cakes in 60 minutes.

-- Each baker takes 60/5 = 12 minutes to produce 1 cake.

-- 6 bakers can produce 6 cakes in 12 minutes.

-- 20 cakes will take 20/6 = (3 and 1/3) as much time as 6 cakes.

-- (3 and 1/3) times 12 minutes = 40 minutes.

================================================

An easier way to do it:

-- 3 bakers produce 15 cakes in 60 minutes.

-- 6 bakers could produce 30cakes in 60 minutes.

-- Only 20 cakes are needed. That's only (20/30) = 2/3 of 30 cakes.

-- So it will only take them 2/3 of 60 minutes = 40 minutes to make them.

Can you solve the equation 2/3(4x-5)=8 by using the Division Property of Equality? Explain.

Nata [24]

To solve for X you need to simplify both sides on the equation
23(4x−5)=8

(23)(4x)+(23)(−5)=8 *Distribute*

8/3x+−10/3=8

after that you add 10/3 on both sides

8/3x+−10/3+10/3=8+10/38/3x=34/3

finally multiply 3/8 on both sides
(3/8) x (8/3x)=(3/8) x (34/3)

and your answer should be
X= 17/4
