x-(x/3)=2
turn x into a fraction x/1
to get x/1 -x/3 = 2
multiply x/1 x 3/3 to get both fractions with same denominator
3x/3 - x/3
(3x-x)/3
3x-x = 2x
so now you have (2x)/3 =2
multiply both sides by 3 to get 2x = 6
divide bothe sides by 2 to get x = 3, which is the answer
The rule for regular polygons are very easy. The number of reflectional symmetries is same as the number of sides. Regular polygons have all sides the same length and all angles same. Reflection symmetry means that you can fold the shape along that line and it will match up.
For this question, we want the number of reflectional symmetries of a regular decagon. Decagon is a 10 sided figure. Hence, the number of reflectional symmetries is 10.
There are 5 symmetry lines from one vertex to opposite vertex and 5 more symmetry lines form midpoint of one side to midpoint of opposite side.
ANSWER: 10
Answer:
If 5x+12=44 then value of 5x-12 is 20
Step-by-step explanation:
5x + 12 = 44
- The first step, we have to find the value of x
5x + 12 = 44
5x = 44 - 12
5x = 32
x = 32/5
x = 6.4
- After that, insert the value of x into 5x - 12
5x - 12 = ...
5 ( 32/5 ) - 12
= 32 - 12
= 20
Answer:
there is a total of 20 students in the class because 60% of 20 is 12
Step-by-step explanation:
pls answer my recent question :(
Step-by-step explanation:
slope=4-6/8-3=-2/5
chosing another point (x,y) we have
y-4/x-8= -2/5
y-4=-2/5(x-8)
y= -2/5x+16/5+4
