3 0

Answer:

(13)

<u>x= 8</u>

<u>y=11</u>

(14)

<u>x= 20</u>

<u>y=20.75</u>

(15)

<u>x=9</u>

<u>y=13</u>

Step-by-step explanation:

(13) 8x-1 = 11x -25

24=3x

<u>x= 8</u>

8(8)-1 +15y-48= 180

15y=165

<u>y=11</u>

(14) 7x-44 + 4x + 4= 180

11x= 220

<u>x= 20</u>

4(20)+4+39= 8y-43

123=8y-43

166=8y

<u>y=20.75</u>

(15) 12x+1=15x-26

3x=27

<u>x=9</u>

28+15(9)-26+4y-9=180

4y=52

<u>y=13</u>

Approximately how much money would Manny have if he invested $1,200 at an interest rate
quester [9]

Answer:

$1,701.64

Step-by-step explanation:

(see attached for reference)

recall that for compound interest, the following formula applies:

A = P [1 + (r/n) ] ^ (nt), where

A = final amount (we are asked to find this)

P = Principal amount = $1,200

r = interest rate = 5% = 0.05

t = 7 years

n = 12

Substituting these into the equation,

A = 1200 [1 + (0.05/12) ] ^ [(12)(7)]

A =  $1,701.64
