Since you have to move the decimal point the the right by 7 places to get the decimal point after the one. You must multiply by 1/10 seven times, which is the same as:
10^-7
The greatest common factor is the largest factor that both terms share.
First, start with the coefficients, 14 and 28. The largest factor they both share is 14. 14 x 1 = 14, 14 x 2 = 28.
Next we move to the variables, abc and a²b²c³. The largest factor the both share is abc, all to the power of 1.
So, your GCF and final answer is 14abc
Car 1
2 miles............................1 minute
10 miles.........................5 minutes
20 miles.........................10 minutes
40 miles..........................20 minutes
car2
1.5 miles...........................1 minute
15miles.............................10 minutes
30 miles...........................20 minutes
the difference is 0.5 miles per minute
0.5*60=30 miles/hour
The answer on a app i have says it’s -3x - 7 so the person above me is right
