Answer:
4x+20=
6x-10
Step-by-step explanation:
Simplifying: 4x + 20 = 6x + -10
Reorder the terms: 20 + 4x = 6x + -10
Reorder the terms: 20 + 4x = -10 + 6x
Solving: 20 + 4x = -10 + 6x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6x' to each side of the equation: 20 + 4x + -6x = -10 + 6x + -6x
Combine like terms: 4x + -6x = -2x: 20 + -2x = -10 + 6x + -6x
Combine like terms: 6x + -6x = 0: 20 + -2x = -10 + 0: 20 + -2x = -10
Add '-20' to each side of the equation: 20 + -20 + -2x = -10 + -20
Combine like terms: 20 + -20 = 0: 0 + -2x = -10 + -20: -2x = -10 + -20
Combine like terms: -10 + -20 = -30: -2x = -30
Divide each side by '-2': x = 15
Simplifying: x = 15

Answer:
7740 degrees.
Step-by-step explanation:
The sum of the exterior angles of all polygons add up to 360 degrees.
So the number of sides and the number of interior angles in this polygon = 360 / 8 = 45.
Each internal angle = 180 - 8 = 172 degrees, so the sum of all interior angles
= 172 * 45
= 7740 degrees,

Answer :
<u>Given</u><u> </u><u>-</u>
- Books read by aya = 5
- Total number of books read by them = 14
<u>To</u><u> </u><u>find</u><u> </u><u>-</u>
- How many books does luka reads.
<u>Solution</u><u> </u><u>-</u>
Here, total number of books is 14 and books read ny aya is 5 . To find the luka reads We'll subtract total number of books read by them from books read by aya.
→ 14 - 5
→ 9
<u>There</u><u>fore</u><u>,</u><u> </u><u>9</u><u> </u><u>books</u><u> </u><u>read</u><u> </u><u>by</u><u> </u><u>luka</u><u>.</u><u> </u>
