Answer:
B
Step-by-step explanation:
Step 1. Factor out the common term 2
n - 2 = 2(5n + 2)/2
Step 2. Cancel 2
n - 2 = 5n + 2
Step 3. Subtract n from both sides
-2 = 5n + 2 - n
Step 4. Simplify 5n + 2 - n to 4n + 2
-2 = 4n + 2
Step 5. Subtract 2 from both sides
-2 - 2 = 4n
Step 6. Simplify -2 - 2 to -4
-4 = 4n
Step 7. Divide both sides by 4
-1 = n
Step 8. Switch sides
n = -1
The answer is letter C.
it’s this because the two first answers are acute and smaller than 90 degrees and 180 is a straight line.
Answer: 18
Step-by-step explanation: Simplify 2^3 to 8. 3/4 (8+4^2). Simplify 4^2 to 16. 3/4 (8+16). Simplify 8+10 to 24. 3/4*24. Use this rule: a/b * c = ac/b. Simplify 3*24 to 72. 72/4.
