Answer:
The correct answer is b.
Step-by-step explanation:


No real solutions.
So the division of a number and -9 or
x/-9
+10=11 or
(x/-9)+10=11
subtract 10 from both sides
x/-9=1
multiply both sides by -9
x=-9

Answer:2=c
Step-by-step explanation:
22=5c+3c-c+8
22-8=5c+3c-c+8-8
14=5c+3c-c+0
14=5c+3c-c
14=8c-2
14=7c
14/7=7c/7
2=c
Check answer by pluging 2 in for c.
5*2+3*2-2+8
=10+6-2+8
=16-2+8
=14+8
=22
The final answer is 2=c
Answer:
option c) x₁₁ + x₁₂ = 8000
Step-by-step explanation:
Given:
xij = gallons of component i used in gasoline j
gallons of component 1 available = 8,000
demand gasoline types 1 = 11,000
demand gasoline types 2 = 14,000
Here, we have only component 1 available i.e i = 1 only
( therefore, all the options containing i = 2 gets eliminated )
thus,
component 1 will fulfill the demand of gasoline types 1 and 2 i.e j = 1 and 2
hence,
the equation satisfying the above conditions comes out as:
x₁₁ + x₁₂ = 8000
that means gallons of component 1 used in gasoline 1 and 2 and the total equals to the gallons of component 1 available i.e 8000
