934-768
line them up:
934
-768
Subtract the ones digit (ie 4-8), if insufficient (ie result is less than zero) subtract one from the tens digit and add ten to the numeral in the ones digit. Repeat process for tens and hundreds. (only works if top number is larger than bottom)
ie. 4-8=-4
934-->924, 4-->14, 14-8=6
ie. 20-60=-40
924-->824, 20-->120, 120-60=60
ie. 800-700=100
answer: 100+60+6=166
7x + 5 = 68 subtract 5 from both sides 7x = 63 divide both sides by 7 x = 9
Factors of 68: 1, 2, 4, 17, 34, 68.Factors of 238: 1, 2, 7, 14, 17, 34, 119, 238.GCF (68, 238) = 34
It simplifies to 7 over 34.
7 over 34
68 = 7b - 9 -7b = -68-9 b = (-68-9)/-7 = 11
The factors of 68 are: 1, 2, 4, 17, 34, 68 The factors of 238 are: 1, 2, 7, 14, 17, 34, 119, 238
You would multiply 7 by 7 34 times. This comes out to be 541,169,560,000,000,000,000,000,000,000,000,000.
7 times with a remainder of 5
n= 7
