81.56+n-2.55=0
81.56+n=2.55
n=2.55-81.56
n=-79.01
Answer:
The second one would be the answer.
Step-by-step explanation:
If you look at the model, it shows it on 125 going down to 90.
If she has $125 and she spends $35 on gas, you would subtract that from how much money she has.
125 - 35 = 90.

Answer:
1.
31, 37, 43, 49, 55
2.
for nth number the value is 31+6(n-1)
3.
24th number, 169-31=138 and 138/6=23
55x5 - 40x5
The third one down
All 3 angles of a triangle add up too 180, so 80+55= 135, 180-135 is 45, so the value of x is 45
