Answer:
x = 1/10
Step-by-step explanation:
1/40 + x = 1/8
Subtract 1/40 from each side
1/40-1/40 + x = 1/8-1/40
x = 1/8 - 1/40
Get a common denominator
x = 1/8 *5/5 - 1/40
x = 5/40 - 1/40
x = 4/40
Simplify
x = 1/10
100 + 10h
The 100 represents the $100 and the 10h represents the $10 times the hours
All real numbers is the domain
{x | x ∈ R}
A.(x + 1 < -1) ∩ (x + 1 < 1)
(x < -2) ∩ (x < 0) = (x < -2)
b.(x ≤ 0) ∩ (x ≥ 0) = {0}
c.(x < 0) ∩ (x > 0)
= Ф
Option C has no solution.
