Hello from MrBillDoesMath!
Answer:
10a. YES
10b. YES
10c. NO
10d . YES
Discussion:
If x = 12
10a. Does (3/4) 12 = 9? Does (36/4) = 9 = 9? YES
10b. Does 3x = 36? Does 3(12) = 36 = 36? YES
10c. Does 5x = 70? Does 5(12) = 60 = 70? NO
10d. Does x/3 = 4? Does 12/3 = 4 = 4 ? YES
Thank you,
MrB
Let us evaluate the equations one at a time.
1) 3x + 5 = -2
3x = -7
x = -7/3
This equation has unique solution.
2) 6(x - 11) = 15 - 4x
6x - 66 = 15 - 4x
10x = 81
x = 81/10
Ths equation has a unique solution
3) 12x + 9 = 8x + 1 + 4x
12x - 8x - 4x = 1 - 9
0x = -8
x = -8/0
This equation has no solution.
4) 2(x - 3) = 10x - 6 - 8x
2x - 6 = 10x - 6 - 8x
2x - 10x + 8x = -6 + 6
0x = 0
x = 0/0
Ths equation has no solution.
5) 5x + 6 = 5x - 4
5x - 5x = -4 - 6
0x = -10
x = -10/0
This equation has no solution.

Answer:
$92
Step-by-step explanation:
First, you need to divide the expense between the 5 nights. So 410/5=82. This is still with the coupon though. You need to add 10. When you do, you get $92/night. So, for five nights without the coupon, he would have spent $460 for the entire trip. Hope this Helps!
