You subtract 3x-9x=-6x
then you add 9+16=25
last you put the two together to get 25-6x so the answer is C
We have two products: a two-slice toaster and a four-slice toaster.
Lets call T the number of two-slice toasters produced and F the number of four-slice toasters produced.
If we have 300 hours per week of labor, the sum of the labor required for T and F has to be lower or equal to that value.
The labor hours that take to make the two-slice toasters can be written as 6*T, as it is the product of the hours per unit (6 hours/unit) by the number of units (T units).
The same can be done for F, where the labor required can be expressed as 10*T.
If we add these terms, and make them be less or equal than 300, we get:

The production capacity is 40 units, so the sum of T and F has to be less or equal than 40.
We can express this as:

Answer:
The system of inequalities for this problem becomes:

6T+10F<=300
T+F<=40
15 is your answer as its 5*3
Answer:
The formula is connecting R and A

The value of 'K' = 18.15
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that R is inversely proportional to A
R ∝ 1 / A

Given R = 12 .1 and A = 1.5


K = 12.1 × 1.5
K = 18.15
The value of 'K' = 18.15
