Answer:
if -5n+7<57, then n>-10.
if 6n+2<8, then n<1.
Step-by-step explanation:
-5n+7<57
1. subtract 7 from both sides:
-5n+7 -7< 57 -7
-5n<50
2. divide both sides by -5 (remember to flip the sign whenever you divide by a negative number):
-5n ÷-5<50 ÷-5
n>-10
6n+2<8
1. subtract 2 from both sides:
6n+2 -2<8 -2
6n<6
2. divide both sides by 6:
6n ÷6<6 ÷6
n<1
LOGa(n)=b i hope this helps.
Answer:
-10 = a
Step-by-step explanation:
17 = a - 3 - За
Combine like terms
17 = -3 -2a
Add 3 to each side
17+3 = -3-2a+3
20 = -2a
Divide by -2
20/-2 = -2a/-2
-10 = a

Sorry if im wrong
Step-by-step explanation:
Add the prices of the food together to get $7. Then you calculate the sales tax, which is 1.04 * $7 = $7.28. The tip is 15% I am assuming, and not 15, so it would be $7 * 0.15 = $1.05. Add $1.05 with $7.28 to get $8.33, so the answer is A.
