Answer:
5
Step-by-step explanation:
3(3x+7) = 3x+51
9x + 21 =3x+51 ; cuz 3 times 3 is 9 and 3 times 7 is 21
subtract 21 so 21 - 21 = 0 and 51 - 21 = 30 so
9x= 3x+30
Then subtract 3! 9-3x and 30 - 3x
You will get 6x = 30
Next you will divide by 6x
Lastly you will get 5! So your answer is 5, sorry it's a little messy but I hope this helps!
You didn’t finish asking the question. So I will say they work differently at different paces.
Answer: 124
Step-by-step explanation: 7^2=49; 13^2=169; 19^2=361. Only 124 cannot be expressed as a square of an integer.
The answer would be x equal or greater than 1/15
1/5 could be replaced with 0.06
24,000 / 3 = 8000 x 2 = 16,000
16,000 / 650 = 24.6 (25) Days
