Answer:
21324 and 3
Step-by-step explanation:
7= 16 lb >16 Oz 16x16=256
8= 1500 lb < 2T 2000+2000
9= 3T>5999 lb 2000x3
10= 1600 Oz > 10 lb 1600÷16=100
11= 19 lb>300 Oz 19x16=304oz
12= 8 oz= 1/2 lb 16 ounces = 1 pound 1/2=8
13= pounds=6000 tons= 1, 1.5
◆ Principle of Mathematical Induction ◆
Answer:

Step-by-step explanation:

Isolate n on one side of the equation.
First, subtract 12 from both sides.
4n+12-12=4-12
Solve.
4-12=-8
4n=-8
Then, divide by 4 from both sides.
4n/4=-8/4
Solve.
Divide the numbers from left to right.
-8/4=-2
n=-2

So, the final answer is n=-2.
