jose invests money in two simple interests account. he invests twice as much in an account paying 13% as he does in an account p
d1i1m1o1n [39]

Answer:

He invested altogether $900

Step-by-step explanation:

* <em>Lets explain how to solve the problem</em>

- Jose invests money in two simple interests account

- He invests twice as much in an account paying 13% as he does in

 an account paying 5%

- That means the amount he invested in the account paying 13% is

  twice the amount he invested in the account paying 5%

- He earns $93.00 in interest in one year from both accounts combined

- We need to find how much he invested in each account

- Assume that he invested $x in the account paying 5%

∵ He invested twice as much in an account paying 13% as he does in

   an account paying 5%

∴ He invested $2x in the account paying 13%

- The simple interest <em>I = PRT</em>, where P is the money invested, R is the

  rate of interest in decimal and t is the time of investment

# <u><em>Account paying 13%</em></u>

∵ P = 2x , R = 13/100 = 0.13 , T = 1

∴ I = 2x(0.13)(1)

∴ I = 0.26 x ⇒ (1)

# <u><em>Account paying 5%</em></u>

∵ P = x , R = 5/100 = 0.05 , T = 1

∴ I = x(0.05)(1)

∴ I = 0.05 x ⇒ (2)

∵ He earns $93.00 in interest in one year from both accounts

- Add (1) and (2) and equate the sum by 93.00

∴ 0.26 x + 0.05 x = 93.00

- Add like terms in the left hand side

∴ 0.31 x = 93.00

- Divide both sides by 0.31

∴ x = 300

∴ 2x = 2(300)

∴ 2x = 600

∵ x represents the amount of money invested in the account paying 5%

∴ <em>The amount of money invested in the account of 5% is $300</em>

∴ <em>The amount of money invested in the account of 13% is $600</em>

- The total amount of money he invested is the sum of the money

  he invested in each account [$300 + $600 = $900]

∴ He invested altogether $900

The area of the rug is 36 1/4 square feet the rug is 8 3/4. what is the length of the rug?
loris [4]
Area=legnth times width

36 and 1/4=8 and 3/4 times width

conver to imrpoer
36 and 1/4=145/4
8 and 3/4=35/4

145/4=35/4 times x
times both sides by 4
145=35 times x
divide both sides by 35
29/7=x
4 and 1/7=x

answer is 4 and 1/7=legnth

Solve |2x - 5| = 4. {x | x = -4.5 or x = 4.5} {x | x = 0.5 or x = 4.5} {x | 0.5 &lt; x &lt; 4.5}
kotykmax [81]

<u><em>Answer:</em></u>

{x | x = 0.5 or x = 4.5}

<u><em>Explanation:</em></u>

<u>Before we begin, remember that:</u>

The modulus gives the positive value of what's inside it.

<u>This means that:</u>

|a| = |-a| = a

<u>Now, for the given, we have:</u>

|2x-5| = 4

<u>From the above rule, we can deduce that:</u>

<u>either:</u>

2x - 5 = 4

2x = 4 + 5 = 9

x = 4.5 ............> first solution

<u>Or:</u>

2x - 5 = -4

2x = 5-4 = 1

x = 0.5 ..........> second solution

<u>Now, we check:</u>

<u>at x = 4.5</u>: |2(4.5)-5| = |9-5| = |4| = 4 ..........> first solution verified

<u>at x = 0.5</u>: |2(0.5)-5| = |1-5| = |-4| = 4 .........> second solution verified

Hope this helps :)
