If the question is in the context of angles, then
x + 20 + x + 10 = 90
ie 2x + 30 = 90
or 2x = 60 which gives x = 30
If: 3x+20 = 2x-10 Then: x = -30
70
To find the value of ( x ), we first need to understand that complementary angles sum to 90 degrees. Thus, we have the equation: [ (2x + 10) + (2x + 20) = 90 ] Simplifying this gives: [ 4x + 30 = 90 ] Subtracting 30 from both sides results in: [ 4x = 60 ] Dividing by 4, we find: [ x = 15 ] So, the value of ( x ) is 15.
20 + 50 + 20 + 10 = 50 = 150
5 + 20 = 25
If: 3x+20 = 2x-10 Then: x = -30
70
20 + 50 + 20 + 10 = 50 = 150
30 or -10 if the 20 is negative.
5 + 20 = 25
2+2+2+10+5+5+5+20+20+20+20+20+20=151
10 plus 20-2 - 11 plus 3 is equal to 20.
Calculate 10^2 - 4*(-16)*(-20)
20 + 10 + 5 = 35
10 + 15 + 20 = 45
-10
14.95 + 20 + 10 + 2.06 = 47.01
