Select the correct answer.

What is the justification for step 3 in the solution process?

10d − 5 = 4d − 15 − 3d

Step 1: 10d − 5 = d − 15

Step 2: 9d − 5 = -15

Step 3: 9d = -10

A.

the subtraction property of equality

B.

the multiplication property of equality

C.

the division property of equality

D.

the addition property of equality

Pretty sure it's C. The division property of equality.

Because on the last step, you divide 9d by 9, to get d. And you also have to divide the other side by 9.

D.

the addition property of equality

Step-by-step explanation:

Given the expression in

Step 2: 9d - 5 = -15

The addition property of equality was used to get step 3.

That is

9d - 5 = -15

Move -5 over the equality sign and it becomes +5

9d = -15 + 5

9d = -10

OR add 5 to both sides of the equation as shown below

9d - 5 +5 = -15 + 5

9d = -10 which we have in step 3

51

step-by-step explanation:

73-22=51 the   mass number minus the amount of protons gives you the amount of neutrons

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
