devlian [24]
<h3>The formula that correctly relates H and L is H = L + 14.8</h3><h3>The high temperature is 83.7 degrees</h3>

<em><u>Solution:</u></em>

Let H represent the high  temperature

Let L represent the low temperature

Given that,

<em><u>The coldest temperature in the city today was 14.8 degrees (Fahrenheit) lower than the hottest temperature</u></em>

L = H - 14.8

Rearrange,

H = L + 14.8

<em><u>If the low temperature was 68.9 degrees, what was the high temperature?</u></em>

L = 68.9

Then,

H = 68.9 + 14.8

H = 83.7

Thus the high temperature is 83.7 degrees
