Hypertension is the term used to describe high blood pressure. Blood pressure is a measurement of the force against the walls of your arteries as your heart pumps blood through your body. Blood pressure readings are usually given as two numbers -- for example, 120 over 80 (written as 120/80 mmHg).
well you only switch inequality signs when dividing or multiplying the opposite side of the equation by a negative number because negative numbers can shift or switch around the graph so you have to flip the inequality sign otherwise you'll get the wrong graph. Jayne Â· 1 year ago.
How do you know when to use â¡ or =? I've seen the the formula for density written with that = and â¡. Also, whilst we're on the topic of symbols, what does an inequality sign with two lines beneath it mean? Is it the same as with one line (greater/less than or equal to)
