Answer: 19 + 14x ≤ 65
Explanation:
$19 is only added once because there is only one DVD purchased. $14 is added an unknown number of times, thus the variable X is included. We know that that the total number of dollars spent for both items is either less than or equal to 65. (Depending on your teacher, they may want you to write "19 + 14x < 65" if they want you to write the answer only for discrete numbers).
2+2 is 4 minus one that's 3 quick maths but 2+1 is equal to 3
Answer:
The number would be 3.
Step-by-step explanation:
This problem can be written as
5x + 9 = 24
So to solve it, you have to isolate x:
5x + 9 = 24
5x + 9 - 9 = 24 - 9
5x = 15
5x÷5 = 15÷5
x = 3
Check:
5(3) + 9
= 15 + 9
= 24
Answer: Yes
Step-by-step explanation:
First multiply the first equation by three to get 3x+12y=69
Then subtract 12y from both sides of the second equation
Then add the first system and the second like this:
Because 0≠70, the system has no solutions
