Answer:
x<9
Step-by-step explanation:
-5(x-1) > -40 ---> divide each side by -5(you flip the inequality because of dividing by negative)
(x-1)<8 ---> add 1 to each side
x<9
Answer:
190 Jeans
Step-by-step explanation:
The daily production cost of the jeans manufacturer is given as:
To determine the number of Jeans,x that should be produced daily to minimize cost, C. We take the derivative of C and solve for its critical points.
Therefore, to minimize daily cost, 190 Jeans is the number of jeans that should be produced daily.
(a−b)+a+(a+b)=45
⟹3a=45
a=15
a(a+b)=300
⟹15(15+b)=300
⟹225+15b=300
⟹15b=300−225
⟹15b15=7515
b=5
a−b=10⟹a=15⟹a+b=20
The three numbers are 10, 15, and 20.
Proof:
10+15+20=45✓
