1m is approximately 3 feet whereas 1m is approximately 3280 feet. Therefore, the best estimate for the heiht of a desk would be 1 m
The answer is B. -3, 3
This is why:
3|3*3| = 27
3|9| = 27
3*9 = 27
The same will happen with -3 since this | means the distance from the number to zero and in this case it is 3 units til you reach zero. So the answer is B. 3, -3
This is pretty easy math.
All we have to do here is multiply the hours times the constant (10$ an hour)
20*10=200$
40*10=400$
60*10=600$
All together he makes 1,200$.
