51 = 3k ( take 3 to the other side )
51/3 = k ( multiplication becomes division )
17 = k
k = 17
Answer:
12308.8 cm^3
Step-by-step explanation:
First we need to fill in the variables for the formula


Now solve. Keep in mind the order of operations. I have rewritten the equation with parenthesis to make it easier

After solving, you should get 12308.8. Since these measurements were in centimeters, we need to add <em>cm</em> to the end. Also since this is in 3D we need to add ^3

Answer:
a = -1/2
b = 2
Step-by-step explanation:
Step 1: Rewrite 1st equation
-b = -5 - 6a
b = 5 + 6a
Step 2: Substitution
4a - 3(5 + 6a) = -8
Step 3: Solve
4a - 15 - 18a = -8
-14a - 15 = -8
-14a = 7
a = -1/2
Step 4: Plug in <em>a</em> to find <em>b</em>
6(-1/2) - b = -5
-3 - b = -5
-b = -2
b = 2
