There is no solution. The output of this equation is equal to -10 = 0 which is obviously not true.

nexus9112 [7]

Answer:

x = 1 and y = 5

Step-by-step explanation:

Use substitution because you know that x = y - 4, and plug this into the first equation to get -10(y - 4) + 3y = 5, or -10y + 40 + 3y = 5. This is -7y = -35 so y = 5. Plug this into the 2nd equation to get that x = 1 and y = 5.

Can anyone help ? i really don’t understand this question <br> If NP bisects X =<br> m/RNM =
snow_tiger [21]

We can conclude that the value of x is (∠MNP + 66)/8 and angle m∠RNM = ∠RNQ - ∠MNP + 78.

<h3>What are angles?</h3>
  • An angle is a figure in Euclidean geometry formed by two rays, called the sides of the angle, that share a common endpoint, called the vertex of the angle.
  • Angles formed by two rays are located in the plane containing the rays.
  • Angles are also formed when two planes intersect.
  • These are known as dihedral angles.

So,

  • ∠MNQ = ∠MNP + ∠PNQ
  • 8x + 12 = ∠MNP + 78
  • 8x + 12 - 78 = ∠MNP
  • 8x - 66 = ∠MNP
  • 8x = ∠MNP + 66
  • x = (∠MNP + 66)/8

Now, substitute 'x = (∠MNP + 66)/8' in 8x + 12:

  • ∠MNQ = 8x + 12
  • ∠MNQ = 8 ×(∠MNP + 66)/8 + 12
  • ∠MNQ = ∠MNP + 66 + 12
  • ∠MNQ = ∠MNP + 78

Hence, m∠RNM = ∠RNQ - ∠MNP + 78

Therefore, in the given question value of x is (∠MNP + 66)/8 and angle m∠RNM = ∠RNQ - ∠MNP + 78.
