Solving Simple Equations
An equation is ____________________________________________________________
_______________________________________________________________________
_____________________________________________________________.
The solution of an equation is the value of the variable that makes the equation __________.
To find the solution of an equation, you want to isolate the variable by using _______________ _______________.
Examples:
X – 10 = 4 2/5 = M – 1/5 N – 3.2 = 5.6
-2.3 + Y = 7 -3/5 + Z = 2/4 H + 2π = 3π
A person’s maximum heart rate is the highest rate, in beats per minute, that the person’s heart should reach. One method to estimate maximum heart rate states that your age added to your maximum heart rate is 220.
Using this method, write and solve an equation to find the maximum heart rate of a 33-year old. Then, write and solve an equation to find the maximum heart rate for you.
More Examples:
[pic] ( 4 (3x ( 27 -[pic] ( (7
[pic]x ( 8 [pic]x ( [pic] 0.09w = 1.8
The distance in miles from the airport that a plane should begin descending, divided by 3, equals the plane’s height above the ground in thousands of feet. If a plane is 10,000 feet above the ground, write and solve an equation to fin the distance at which the pilot should begin descending.
Progress Monitoring: How do you feel about your level of understanding of solving simple equations? (Rate yourself from 0 (don’t understand at all) to 10 (doing awesome))
