Ada is showing her work in simplifying (5.9 - 1.8) - 6.2 + 4.1. in which step did ada make an error? (5 points)
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 4 is where she made the error.

Step-by-step explanation:

This step is actually known as the commutative property. That property states that we can change the order of numbers as long as we keep the signs and it maintains it's validity.

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !

step-by-step explanation:

total amount to be paid = $19.5

step-by-step explanation:

given ,

original price = $25.99

discount = 25%

discount amount = 25% of original price

discount amount = 25/100   * 25.99

discount amount = $6.49

hence , the total amount to be paid = original price - discount amount

                                                            = $25.99 - $6.49

                                                            =$19.5

total amount to be paid = $19.5
