Question

Apply the Distributive Property first to solve the equation below. What operation will you need to use​ last? If​ instead, you divide first to solve the equation what operation would you need to use​ last?

18 (d/2-5) = 171

If you apply the Distributive Property​ first, what operation will you need to use​ last?
Multiplication
Addition
Division
Subtraction

If​ instead, you divide first to solve the equation what operation would you need to use​ last?
Division
Multiplication
Subtraction
Addition

Answer 1

Explanation:

18 (d/2-5) = 171

1. If you apply the Distributive Property​ first, what operation will you need to use​ last?

a. Multiplication

b. Addition

c. Division

d. Subtraction

18 (d/2-5) = 171

`18((d)/(2)-5)=171 \\\\18((d)/(2))+18(-5)=171\\\\(18d)/(2) -90=171\\\\9d-90=171\\\\+90\ \ \ \ \ +90\\\\9d = 261\\\\/9 \ \ \ \ /9`<== division was used last

`d = 29`

2. If​ instead, you divide first to solve the equation what operation would you need to use​ last?

a. Division

b. Multiplication

c. Subtraction

d. Addition

Recall that in the previous question, we started with multiplication and ended with division. Now, it's switched. Division comes first, then multiplication.

Hope this helps!
