A manufacturer produces both two-slice and four-slice toasters. The two-slice toaster takes 6 hours of labor to produce and the
frosja888 [35]

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:

6T+10F\le300

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:

T+F\le40

Answer:

The system of inequalities for this problem becomes:

\begin{gathered} 6T+10F\le300 \\ T+F\le40 \end{gathered}

6T+10F<=300

T+F<=40

7n - 4 (8n+4) = 159
Romashka [77]

Answer:

n = -7

Step-by-step explanation:

Use distributive property:

7n - 32n - 16 = 159

Combine like terms

-25n - 16 = 159

Add 16 to both sides to isolate variable n

-25n = 175

Divide both sides by -25 to isolate variable n

n = -7

Check your work:

7(-7) - 32(-7) - 16 = 159

-49 + 224 - 16 = 159

159 = 159

Which number produces an irrational number when added to 0.4?
Natalka [10]
0.4 is rational.
Any irrational added to a rational is irrational.
Therefore we only need to add ANY irrational to 0.4 to produce an irrational number.
Examples of irrational numbers are: pi, e, sqrt(2), sin(pi/3), tan30 degrees, etc.
