and Kevin collect coins. Karen has x coins. Kevin has 3 coins fewer than two times the number of coins Karen has. Write and simplify an expression for the total number of coins Karen and Kevin have.

fahrenheit

step-by-step explanation:

fahrenheit is more precise than celsius. the ambient temperature on most of the inhabited world ranges from -20 degrees fahrenheit to 110 degrees fahrenheit—a 130-degree range. on the celsius scale, that range is from -28.8 degrees to 43.3 degrees—a 72.1-degree range. this means that you can get a more exact measurement of the air temperature using fahrenheit because it uses almost twice the scale.

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled

3

step-by-step explanation:

divide 13.5 by 9 to get the scale factor. it equals 1.5

2 * 1.5 = 3
