What value of x makes the vertical parts of the letter N parallel? (4x + 12)°7x° When x = , the alternate interior angles are co

Snezhnost [94]

Answer:

x = 4

Step-by-step explanation:

We assume that the given expessions represent the measures of the alternate interior angles, so are equal.

... (4x + 12)° = 7x°

... 12 = 3x . . . . . . . divide by degrees, subtract 4x

... 4 = x . . . . . . . . . divide by 3

_____

Then the angles are 7x° = 28° = (4x+12)°.

A number is equal to twice a smaller number plus 3. The same number is equal to twice the sum of the smaller number and 1. How m

Pie

Answer:

No solutions exist because the situation describes two lines that have the same slope and different y-intercepts.

Step-by-step explanation:

This question can be solved by a system of equations.

I am going to call the numbers x and y.

A number is equal to twice a smaller number plus 3.

Greater number is x, and smaller is y. So

$x = 2y + 3$

The same number is equal to twice the sum of the smaller number and 1.

This means that $x = 2y + 1$

Equaling the values for x:

$2y + 3 = 2y + 1$

$0y = -2$

$y = -\frac{2}{0}$

Since division by 0 does not exist, it means that there is no solution for the system.
