Rob saved $30. Do you have to explain, if so since he saved $6 for every $15, you would do 75 divided by 15 which is 5 then you would do 5 times 6 which gives you 30.
Answer: (x+5) (x+2)
Explanation: tell me if you want the explanation
6r - 3t = 6 /*8
6r + 8t = - 16 /*3
48r - 24t = 48
48r + 24t = - 48
---------------------- +
96r = 0
r = 0
t = ( -16 + 6r)/8 = - 16/8 = - 2
Answer:
3.5
Step-by-step explanation:
This is because 12 times 4 is 48 and if you divide 168 by 48 you get 3.5 . 3.5 times 12 times 4 is 168.
