Twice (2 x ) a number (n), subtracted (-) from 36, is less than (<) 15 more than (+) one-third (1/3) the number (n).
36 - 2n < 15 + 1/3n Subtract 15 from both sides
21 - 2n < 1/3n Add 2n to both sides
21 < 7/3n Multiply both sides by 3/7 to cancel out the fraction
63/7 < n Simplify the fraction
9 < n Switch the sides to make it easier to read
n > 9
The possible values for the number are anything over 9.
Answer:
X = 50
Step-by-step explanation:
180-80=100. 100/2=50
50+50+80=180
All angles add,up to 180
Sum of inside angles of a polygon= 180º(n-2)
n=number of sides.
This polygon has 6 sides, the sum of all its angles would be=180º(6-2)=720
let´s:
xº=inside angle
xº=720º-sum of the others inside angles.
xº=720º-(75º+130º+120º+105º+145º)=720º-575º=145º
yº=180º-xº=180º-145º=35º
Answer: yº=35º
Answer: 9 x 3 = 27
9 times 3 is equal to 27
It is the symmetric property
