2

Linear Equations are used to solve real life problems

Conversions, Perimeter, Measures, Physics, Business, etc...

3

Converting between different measures is a great example for the need to solve equations.

Multiple Choice

The formula to convert Celsius to Fahrenheit is F = 1.8C + 32. Which equation would be used to find the degrees in Celcius when the temperature is 68 degrees fahrenheit?

1

F = 1.8(68) + 32

2

68 = 1.8C + 32

5

Multiple Choice

Identify the first step when solving:


68 = 1.8C + 32

1

add 32

2

subtract 32

3

divide by 1.8

4

subtract 68

Multiple Choice

Speed of falling objects can be determined using v = gt where which we can rewrite as v = 32t since g is the acceleration due to gravity and is 32 ft/sec2


Which equation would be used to determine the time it takes a falling ball to reach a velocity of 176 ft/sec

1

176 = 32t

2

v = 32(176)

Multiple Choice

Impulse can be represented by

 Δp = m(vf  vi)\Delta p\ =\ m\left(v_f\ -\ v_i\right) 

What is the first step needed to find the final velocity of an object given the following equation for impulse:

100 = 25(v - 10) 

1

add 10

2

subtract 25

3

distribute 25
