3x-8<=23 AND -4x+26>=6

bazaltina [42]

Answer:

Step 1: Solve for x in the first equation

$3x-8+8\leq 23+8$

$3x\leq 31$

$3x/3\leq 31/3$

$x\leq \frac{31}{3}$

Step 2: Solve for x in the second equation

$-4x + 26-26 \geq 6-26$

$-4x\geq -20$

$-4x/-4\geq -20/-4$

Since you divide by a negative, you must flip the sign.

$x\leq 5$

How do I find the sum of the measures of the marked angles?

Afina-wow [57]

Answer:

The sum of the marked angles = Total angles on the 4 straight lines – Sum of the interior angles of the quadrilateral. Sum of interior angles of polygon of 4 sides = (4 – 2) *1800 =3600

Hence, sum of the marked angles = 4 * 180° – 360° = 720° – 360° = 360°
