Answer:
x = 7
Step-by-step explanation:
3x + 20 = 5x + 6
3x - 5x = 6 - 20
-2x = -14
x = 14/2
x = 7
the value of x = 7

Answer:
A x =30
Step-by-step explanation:
(y+x) and (y-x) make a straight line so they add to 180 degrees
(y+x) + (y-x) = 180
Combine like terms
y+y+x-x=180
2y=180
Divide by 2
2y/2 = 180/2
y= 90
(y+x) and 2x make a straight line so they add to 180 degrees
y+x+2x = 180
Combine like terms
y+3x = 180
Since we know y we can substitute it in
90+3x = 180
Subtract 90 from each side
90-90+3x= 180-90
3x = 90
Divide by 3
3x/3 = 90/3
x= 30
27 is 60 percent of 45. I got this answer by dividing 27 by .60 also to check your answer you can multiply 45 by .60 and if you get 27 the answer is correct
