Eva is showing her work in simplifying (7.3 – 7.2) – 3.8 + 3.7. in which step did eva make an error? step 1: (7.3 – 7.2) – 3.8 + 3.7 step 2: 7.3 + (–7.2 – 3.8) + 3.7 (commutative property) step 3: 7.3 – 11 + 3.7 step 4: 7.3 + 3.7 – 11 (commutative property) step 5: 11 – 11 = 0 step 2; she wrote commutative instead of distributive step 4; she wrote commutative instead of distributive step 4; she wrote commutative instead of associative step 2; she wrote commutative instead of associative

Mistake made by Eva is:

Step 2; she wrote commutative instead of associative

Step-by-step explanation:

Associative property states that if a,b and c are three elements then,

a+(b+c)=(a+b)+c

and Commutative property states that

a+b=b+a

Step 1: (7.3 – 7.2) – 3.8 + 3.7

Step 2: 7.3 + (–7.2 – 3.8) + 3.7 (associative property)

Step 3: 7.3 – 11 + 3.7

Step 4: 7.3 + 3.7 – 11 (commutative property)

Step 5: 11 – 11 = 0

Hence, Mistake made by Eva is:

Step 2; she wrote commutative instead of associative

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.
