SOMEONE PLZ HELP I WILL GIVE 20POINTS IF U ANSWER 2 QUESTIONS
PLZ QUICKLY :)

a) M=1/2t

b) x

=

1

2

y

+

−

1

2

Step-by-step explanation:

Rewrite the equation as 2m=t.

2m=t

Divide each term by 2 and simplify.

m=t/2

Isolate the variable by dividing each side by factors that don't contain the variable.

x=y/2−1/2

Step-by-step explanation:

Hope it is helpful

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
