What is the best estimate for the product of 289 and 7
2 answers:
The best estimate is 2100. Because 289 rounded to the nearest hundredth is 300, and by using simple time tables (3 * 7 = 21), we can determine that 300 * 7 = 2100. But if you want an even closer estimate, do this: (200 * 7) + (90 * 7) = (1400) + (630) = 2030. And to get the exact answer... (200 * 7) + (80 * 7) + (9 * 7) = (1400) + (560) + (63) = (1960) + (63) = 2023. 2032 is the exact answer. The two solutions above involve the usage of time tables and place-value manipulation - (ab) * c = a*c + b*c, in which ab represents a 2 digit number)

We have to start by creating an equation. Cost of System = x Cost of games = 3x Thus x + 3x = $500 Now we find x. 4x = 500, x = 500/4 = 125 So the system is 125, The games, 125*3 = 375
Answer:
6^8
Step-by-step explanation:
6^4 * 6^4
We know that a^b * a^c = a^(b+c)
6^4 * 6^4 = 6^(4+4) = 6^8
