4s-5-3s
=s-5
The s and 5 can not subtract because they aren't like terms. Like terms have the same variable.
Let F = father's age Let S = son's age F = 3S F - 5 = 4(S-5) F - 5 = 4S -20 F = 4S - 15 F = 3S 3S = 4S-15 S = 15, age of son
diggy has iphone 4s or 5
It is only because we count in tens - and 5 10 and 2 are factors.
14s 2d 7 - 6s 4d 5 + 8s 2d 3/2s 2d = 14s 7 - 3s 2s 5 + 4s 3
No. iPhone 5 is not better than the iPhone 4S.
5 of them with a remainder of 1
The iPhone 4S (and also the 5) has an 8 megapixel camera. The only difference between the 4S and 5's camera is the 5 has better low-light performance.
It's not solvable: Proof that it's not solvable: 2 simultaneous equations - let F =father and S=son F = 4S (father is 4 times son's age) and F-5=7S (father minus 5 years equals 7 times son's age). Combining both gives 4S=7S+5 which is 3S=-5. Clearly you cannot have a negative age, which makes the question nonsensical.
The quotient is the answer to a division problem. For example, 10/2=5. The quotient is five.
s = 15
iPhone 5
3s and 3p, remember Cl has 7 valance electron. 3s^2 and 3p^5
