Answer:
8 tables
Step-by-step explanation:
since she makes on average $18 per table and wants to make $180 we can just multiply $18 by 10 tables however we have to take into account the $36 she makes per night. 36 is just 18 multiplied by 2 meaning we can subtract a total of 2 tables away from the total of 10 tables to get 8 tables
Answer:
x ∈ (-oo ; 3)
Step-by-step explanation:
4x - 7 < 5
4x < 5 + 7
4x < 12
x < 12 : 4
x < 3
x ∈ (-oo ; 3)
The answer is -64 or -2^6
Equation: a^2 + b^2 = c^2
18^2 + 16^2 = c^2
324 + 256 = c^2
C^2 = square root 580
Square root 580 reduces to 2 square root 145.
As a decimal that is: 24.08
Rounded to the nearest tenth: 24 inches.
I hope this helps! If it does please offer me the brainiest!
