Answer:

first I would combine terms which would give me

0=0

lastly I would verify the solution

infinite solutions

Step-by-step explanation:

combining combining like terms would give you negative 4x - 7 which is equal to -7 - 4x. if you were to add 7 on either side and 4 on either side you would get 0 = 0 because this is correct it's infinite solutions

What is the value of the angle marked with x?
morpeh [17]

Given:

Quadrilateral with opposite lines are parallel.

To find:

The value of x

Solution:

Quadrilateral with opposite lines are parallel.

Therefore the quadrilateral is a parallelogram.

In parallelogram, the adjacent angles are supplementary angles.

⇒ 48° + x = 180°

Subtract 48° from both sides.

⇒ 48° + x - 48° = 180° - 48°

⇒ x = 132°

The value of the angle x is 132°.

olya-2409 [2.1K]

Answer:

b) 10 to 20

Step-by-step explanation:

You have to multiply each of the given numbers by 4, and add 8 to that result.

So:

  • 0*4+8  = 8
  • 10*4+8 = 48
  • 20*4+8 = 88
  • 30*4+8 = 128
  • 40*4+8 = 168

And 60 is between the result of <u>10 and 20</u>, so that's the interval you have to select.

<em>The correct answer is b) 10 to 20</em>
