Part A: Solve the equation 7x + 3x − 18 = 6(x + 3), and show your work. (5 points) Part B: Use this list of properties to justify each step of your math work. Justifications may be used more than once if needed. (5 points) Distributive Property Subtraction Property of Equality Combine Like Terms Multiplication Property of Equality Division Property of Equality Given Addition Property of Equality

Step-by-step explanation:

So we have the equation:

Steps:

1) Combine Like Terms (left):

2) Distribute Property (right):

3) Addition Property of Equality (add 18 to both sides):

4) Subtraction Property of Equality (subtract 6x from both sides):

5) Division Property of Equality (divide both sides by 4):

So, the value of x is 9 :)

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
