3) John has decided to invest his $20,000 in two saving accounts. He decides to invest some of it at 4.5% annual interest and th

Elza [17]

The amount he invested in the account that yields 4.5% interest is $7,500.

The amount he invested in the account that yields 2.5% interest is $12,500.

<h3>What is the system of equations that represent the question?</h3>

a + b = $20,000 equation 1

0.045a + 0.025b = $750 equation 2

Where:

a = amount he invested in the account that yields 4.5% interest

b = amount he invested in the account that yields 2.5% interest

<h3>How much was invested in the account that yields 4.5% interest?</h3>

Multiply equation 1 by 0.025

0.025a + 0.025b = 500 equation 3

Subtract equation 3 from 2

250 = 0.02a

a = 12,500

<h3>How much was invested in the account that yields 4.5% interest?</h3>

Subtract 12,500 from 20,000

20,000 - 12,500 = $7,500

Ugo [173]

The temperatures can be plotted and labelled on a number line as shown in the image attached below (see attachment).

Temperature can be represented on a vertical number line with 0 representing 0°F.

Temperatures above 0°F will be located above 0, while temperatures below 0°F will be located below 0.

Given the following temperatures: <em>-3.5℉ , 5℉, 1.5℉, -0.5℉, -2℉, 2.5℉ and -4℉</em>

Therefore, the temperatures can be plotted and labelled on a number line as shown in the image attached below (see attachment).
