Answer:

part a:60    part b:9

Step-by-step explanation:

part a:

5,10,15,20,25,30,35,40,45,50,55,60,65

12,24,36,48,60

60 is the lowest number that's common in both

part b:

72=2×2×2×3×3×8

81=3×3×3×3

group the common ones so 2 pairs of 3 and 3's cancel out .

so 3 times 3 is 9

Adrienne invested a total of $2900.00 in two simple-interest money market accounts. Account A paid 3% annual interest and accoun
Butoxors [25]

Solving the system of equations, it is found that Adrienne invested $1,366.67 in account A and $1,533.33 in account B.

<h3>System of equations:</h3>

The variables are:

  • Variable A: Amount invested in account A.
  • Variable B: Amount invested in account B.

The equations are:

a + b = 2900

0.03a + 0.05b = 133

From the first equation:

a = 2900 - b

Replacing on the second:

0.03a + 0.05b = 133

0.03(2900 - b) + 0.05b = 133

0.03b = 46

b = \frac{46}{0.03}

b = 1533.33

Then, on the <em>first </em>equation:

a = 2900 - b = 2900 - 1533.33 = 1366.67&#10;

Hence, Adrienne invested $1,366.67 in account A and $1,533.33 in account B.
