The GCF is 7a.
A prime number times a prime number is a composite number. Since prime numbers, except for 2, are odd numbers, a prime number times a prime number is usually an odd number. It will only be an even number if one of the prime numbers is 2. A prime number times a prime number will be a number with four factors unless both prime numbers are the same, in which case it will be a square number with only three factors.
101 is a prime number. The only factor of 101 is itself and 1.prime
7a
9a-a = 19+7a 8a = 19+7a 8a - 7a = 19 + 7a - 7a 1a = 19 a = 19
It is: 2a+5a = 7a when simplified
1st, let: a= the number you are searching for, of which 105 is 35% of. because fractions are better to work with than percentage or decimals, 35%=7/20 therefore, 105=7a/20 105x20=7a 2100=7a a=2100/7 therefore a=300 to crosscheck, 35% of 300=105
"A" is not used as a symbol in the periodic table. Each element is represented by a unique symbol, such as "H" for hydrogen or "Na" for sodium. If you meant "7A" as a group number, group 7A includes the halogens (fluorine, chlorine, bromine, iodine, and astatine).
5a + 3 = 7a - 1 add 1 to both sides 5a + 4 = 7a so 4 = 2a as 5a + 2a = 7a 4 = 2a = 2 x 2 so a = 2 Check: then 5a + 3 = 10 + 3 = 13 and 7a - 1 = 14 - 1 = 13
7a 7a * 4 = 28a 7a * 7b = 49ab
7a+a=8a
-7a + 3a = -4a
It is: 7a/5xy
The relevant expression is 7a.
The variable is a. You can solve for it, like this: 8a - 9 = 7a - 6 8a = 7a + 3 8a - 7a = 3 a = 3
