91 = 13 x 7 Can't go any further as both 13 and 7 are prime numbers.
9 and 13 both go into 117.
x - 7 - 4 = 13 (-7 - 4 = -13) x - 11 = 13 add 11 to both sides x = 24
the answer -7+x=13 add 7 to both sides. cancel the first set of sevens leavening you with the x and add 13+7=20
7/13 is already in its most sim plified form. Reason ; both '7' and '13' are prime numbers , and therefore do not have any common factors.
91 = 13 x 7 Can't go any further as both 13 and 7 are prime numbers.
9 and 13 both go into 117.
91 divided by 13 = 7 13 can go into 91 7 times
-8x -7 = 3x - 13 Add 8x to both sides: -7 = 11x - 13 Add 13 to both sides: 6 = 11x Divide both sides by 11: x = 6/11
16 and 13 both go into any multiple of 208 .
7, remainder 7
The prime factorization of 91 is 13 x 7 They are both prime so its a prime factorization
x - 7 - 4 = 13 (-7 - 4 = -13) x - 11 = 13 add 11 to both sides x = 24
Both are prime numbers and a prime number is only divisible by 1 and itself.
the answer -7+x=13 add 7 to both sides. cancel the first set of sevens leavening you with the x and add 13+7=20
7/13 is already in its most sim plified form. Reason ; both '7' and '13' are prime numbers , and therefore do not have any common factors.
13 is a prime number so only 13 and one can go into it
