What are the illnesses caused by heat exposure?
The risk of heat-related illness varies from person to person. A person’s general health also influences how well the person adapts to heat (and cold). Those with extra weight often have trouble in hot situations as the body has difficulty maintaining a good heat balance. Age (particularly for people about 45 years and older), poor general health, and a low level of fitness will make people more susceptible to feeling the extremes of heat.
Medical conditions can also increase how susceptible the body is. People with heart disease, high blood pressure, respiratory disease and uncontrolled diabetes may need to take special precautions. In addition, people with skin diseases and rashes may be more susceptible to heat.
Heat exposure causes the following illnesses:
Heat exhaustion is caused by loss of body water and salt through excessive sweating. Signs and symptoms of heat exhaustion include: heavy sweating, weakness, dizziness, visual disturbances, intense thirst, nausea, headache, vomiting, diarrhea, muscle cramps, breathlessness, palpitations, tingling and numbness of the hands and feet. Recovery occurs after resting in a cool area and consuming cool salted drinks.

A negative number(-6) * a negative number(-4) will always equal a positive number(+24). Same with division. A negative number(-24) / a negative number(-6) will always equal a positive number(+4).
Negative Rules:
Multiplication and Division
-5 * -7 = 35
-5 * 7 = -35
-35/-7 = 5
-35/7 or 35/-7 = -5
Addition and Subtraction
-9 + -5 = -14
-9 + 5 or 5 + -9 = -4
-7 - (-5) = -2 > you cannot minus a negative, the number will become positive.
-7 + 5
6 - (-5) = 11
6 + 5
All positive numbers the answer will be positive.
8 + 9 = 17
17 - 8 = 9
6 * 7 = 42
42/7 = 6

Fabrics
-
There are two common types of fabric used in retractable awnings: laminated fabric and woven acrylic fabric. Laminated fabric is the industry standard, consisting of a center denier scrim sandwiched between two colorized layers, which are then sandwiched between two layers of protective lamination. Woven acrylic fabric is a single woven and colorized acrylic layer sandwiched between protective laminations.

Problem: Addition Method > Multiply the first equation by 4
x + 2y = 2
-4x + 3y = 25
4(x + 2y) = 4(2) = 4x + 8y = 8
Now put problem back together with new equation. The 4x's will cancel out.
4x + 8y = 8
-4x + 3y = 25
____________________
11y = 33 > divide by 11 on both sides
11 11
y = 3
Now solve for x. Use either equation and put 3 for the value of y.
x + 2(3) = 2
x + 6 = 2 > now subtract 6 on both sides
x + 6 - 6 = 2 - 6
x = -4
Solution:
(-4, 3)
