a = 28.

Step-by-step explanation:

{a}n = a  + (n - 1)d

4 = a + (7 - 1)( - 4)

4 = a + 6( - 4)

4 = a + ( - 24)

4 = a - 24

4 + 24 = a

28 = a

(OR)

a = 28.

Keiko has a total of $ 5200 comma which she has invested in two accounts. The larger account is $ 900 greater than the smaller a
Ilia_Sergeevich [38]

Keiko has a total of $5200

x is the amount of money in larger account

y is the amount of money in smaller account

x - y = $900

and x + y = $5200

<u>This creates two simultaneous equations:</u>

x - y = $900 ... (i)

x + y = $5200 ... (ii)

Adding (i) and (ii) :

2x = $6100 , x = $3050

y = x - $900 = $3050 - $900 = $2150

The amount of money in larger account (x) = $3050

The amount of money in smaller account (y) = $2150
