What can 5 and 7 both go into
70
Factor them both. 1 x 5 = 5 1 x 7 = 7 Discard the common factor (1) and combine the remaining ones 5 x 7 = 35 35 is the lowest (least) number that both 5 and 7 will go into evenly.
1, 5, 7, 35.
35 is the LCM of the numbers 7 and 5 because 7 multiplied by 5 is 35 and 35 is the lowest number that both 7 and 5 will go into.List the multiples.5, 10, 15, 20, 25, 30, 35, 407, 14, 21, 28, 35, 4235 is the smallest (least) number that appears on both lists.
5, 7, and 3 go into 105.
the biggest number that can go into both 10 and 35 is 5. so 5 goes into 10, 2 times and 5 goes into 35, 7 times so the answer is 2/7
Both numbers add up to 7
-12
5 and 7 are both prime numbers.
5a - 5 = 7 + 2a ( subtract 2a from both sides) 3a - 5 = 7 (add 5 to both sides) 3a = 12 ( divide both sides by 3) a = 4
14 = 2*7 49 = 7*7 So 1, -1, 7, -7 all go into both 14 and 49.
7+8x-5 = 8x+7-5x Subtract 7 from both sides: 8x-5 = 8x-5x Subtract 8x from both sides: -5 = -5x Divide both sides by -5: x = 1 So the equation implies x = 1
