Ada is showing her work in simplifying (5.9 – 1.8) – 6.2 + 4.1. in which step did ada make an error? step 1: (5.9 – 1.8) – 6.2 + 4.1 step 2: 5.9 + (–1.8 – 6.2) + 4.1 (associative property) step 3: 5.9 – 8 + 4.1 step 4: 5.9 + 4.1 – 8 (associative property) step 5: 10 – 8 = 2 step 2; she wrote associative instead of commutative step 2; she wrote associative instead of distributive step 4; she wrote associative instead of commutative step 4; she wrote associative instead of distributive

C Step 4: She wrote associative property instead of commutative .

Step-by-step explanation:

We are given that Ada is showing her work in simplifying

(5.9-1.8)-6.2+4.1

We have to find Ada makes an error

Step 1:(5.9-1.8)-6.2+4.1

Step 2: 5.9+(-1.8-6.2)+4.1

Associative property : (a+b)+c=a+(b+c)

Step 3:5.9-8+4.1

Step 4 : 5.9 +4.1-8

Using commutative property

Step 5: 10-8=2

Ada makes an error in step 4. By using associative property in place of commutative property

Option C is true.

Answer : C Step 4: She wrote associative property instead of commutative .

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

the answer is 62.8 cubic units
