Answer:
x = 14
A = 38
B = 71
C = 71
Step-by-step explanation:
3x-4 + 5x + 1 + 7x-27 = 180
15x-30 = 180
15x = 180 + 30
15x = 210
x = 210/15
x = 14
A = 3x-4 = 3(14) - 4 = 38
B = 5x + 1 = 5(14) + 1 = 70 + 1 = 71
C = 7x - 27 = 7(14) - 27 = 98-27 = 71
Hello!
If you divided by two then added 8 to reach 17, simply reverse the process, like so:
17 - 8 = 9
9 * 2 = 18
<u>Jordan's allowance is $18</u>
I hope this helps, and have a nice day!

Answer: n is greater than or equals to 1, where n is an integer
Step-by-step explanation:
Answer: No, it is not a solution
Work Shown:
-2 ≤ k/3
-2 ≤ -9/3
-2 ≤ -3
The last inequality is false because -3 should be smaller than -2 (not the other way around). Use a number line to help see this.
Since the last inequality is false, the original inequality must also be false for that particular k value. Therefore, k = -9 is not a solution.
