Answer:

You would explain what I did in the step by step explanation.

Step-by-step explanation:

There are three types of triangles: equilateral, isosceles, and scalene. An equilateral triangle has all 3 sides congruent, an isosceles has only 2 sides congruent, and a scalene has no sides congruent. So, if the triangle has marked sides congruent, or you have found some sides congruent, then you look at the amount of sides congruent, and then you can find the type of triangle. For example, if you have a triangle called ABC, and AB and BC are congruent but AC is not, then it is Isosceles because 2 sides are congruent. You would explain the 3 triangle definitions to your friend.

Answers:

<u>24000 dollars</u> invested at 4%
<u>18000 dollars</u> was invested at 7%

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

Work Shown:

x = amount invested at 4%

If she invests x dollars at 4%, then the rest (42000-x) must be invested at the other rate of 7%

She earns 0.04x dollars from that first account and 0.07(42000-x) dollars from the second account

This means we have

0.04x+0.07(42000-x)

0.04x+0.07*42000-0.07x

0.04x+2940-0.07x

-0.03x+2940

This represents the total amount of money earned after 1 year.

We're told the amount earned in interest is $2220, so we can say,

-0.03x+2940 = 2220

-0.03x = 2220-2940

-0.03x = -720

x = -720/(-0.03)

x = 24000 dollars is the amount invested at 4%

42000-x = 42000-24000 = 18000 dollars was invested at 7%

----------------------

As a check, we can see that

18000+24000 = 42000

and also

0.04x = 0.04*24000 = 960 earned from the first account

0.07*18000 = 1260 earned from the second account

1260+960 = 2220 is the total interest earned from both accounts combined

This confirms our answers.
