5x - 2 = 8x + 5.
-2 = -5x + 8x + 5
-2 = 3x +5
-7 = 3x
-7/3 = -2.3
Answer:
y = 1.33
Step-by-step explanation:
What you could do is :
x-1x = 2y + 1x-1x + y = 4
get rid of the x
>>> 2y + y = 4
then combine the like terms or y:
2y + y
>>> 3y = 4
finally: divide 4/3
3y/3= 4/3
>>> y = 1.33
Hope it Helps!
I assume you mean ' 85 ' and not ' 8585 '.
-- 85 is an odd number.
-- If the sum of 2 numbers is odd, then
one of them is odd and the other is even.
-- The only even prime number is 2 .
-- So 85 is the sum of 2 and 83 .
-- Their product is 166 .
Answer:
72 sides
Step-by-step explanation:
The sum of the angles of a polygon with n sides is (n−2) × 180
Since the polygon is regular, we can divide by the number of sides to find the measure of each angle (n−2) × 180 / n
Each angle is equal to 175
(n−2) × 180 / n = 175
Multiply each side by n
(n-2)180 = 175n
Distribute
180n -360 = 175n
Subtract 180n from each side
180n-180n-360 = 175n-180n
-360 = -5n
Divide each side by -5
-360/-5 =-5n/-5
72 = n
There are 72 sides
