The fractions you're given can be simplified down, so you get (12 ÷ 3) 4 hours on Monday, (21 ÷ 3) 7 hours on Tuesday, and (22 ÷ 3) 7 1/3 hours on Wednesday. You can now add these up and get your answer as 18 1/3 hours, or 18.33.

I hope this helps!

Which value of k would cause the system of linear equations 35 x 14 y = 119 and 5 x 2 y = k to have an infinite number of soluti
larisa86 [58]

To solve the question we must know about the System of equations.

<h2>System of equation</h2>

<h2>Inconsistent System</h2>

A system of equations to have no real solution, the lines of the equations must be parallel to each other.

<h2>Consistent System</h2><h3>1. Dependent Consistent System</h3>

A system of the equation to be Dependent Consistent System the system must have multiple solutions for which the lines of the equation must be coinciding.

<h3>2. Independent Consistent System</h3>

A system of the equation to be Independent Consistent System the system must have one unique solution for which the lines of the equation must intersect at a particular.

The value of k should be 17 so that the system of equations gives infinite number of solutions.

<h2>Explanation</h2>

Given to us

  • 35x + 14y = 119
  • 5x +2y = k

As we know that for a system of equations to give an infinite number of solutions. the equations of the system must be either same or in ratio.

<h3>In Equation 1</h3>

35x + 14y = 119,

dividing both the sides of the equation by 7,

\dfrac{35x + 14y}{7} = \dfrac{119}{7}\\\\&#10;\dfrac{35x}{7}+\dfrac{14y}{7} = \dfrac{119}{7}\\&#10;5x+2y = 17

As already discussed the system of equations to give infinite number of solutions, the equations must be the same. therefore, comparing both the equations we see that the value of k should be 17.

Hence, the value of k should be 17, so that the system of equations gives infinite number of solutions.

<h3>Verification</h3>

As we can see in the below image on equating the value of k as 17, the line of the system of equations coincides, therefore, the system will have infinite number of solutions.

Which polynomial is a monomial? A.5r^2s^3t^4 B.2p^2-p C.1-2x+5x4 D.6-2x^3-4x^2+x^5
N76 [4]

For this case we have that by definition, a monomial is an algebraic expression that consists of a single term or in which the terms that form it are related by the product operation.

<em>Example:</em>

-4x * y ^ 2 * z ^ 3

Thus, the correct option is option A.

5r ^ 2 * s ^ 3 * t ^ 4

Answer:

Option A
