5x + 2/2 = 2x - 1
2/2 is basically 1 so
5x + 1 = 2x - 1
isolate the variable
5x + 1 = 2x - 1
-1 -1
5x = 2x -2
-2x -2x
3x = -2
solve
3x/3=-2/3
x=-2/3
Answer:
r=94.2
Step-by-step explanation:
C=pi`d
C=3.14 multiplied by 30
C equals about 94.2
Answer:
Angle A is 77°
x = 3
AC = 13
Step-by-step explanation:
Angles A, B and C MUST add up to 180°. If Angle C is 26°, then the sum of A and B and 26° = 180°. In other words, A+B = 180° - 26° = 154.
Since A and B are equal, A = B = 154°/2 = 77°
Since this triangle is isosceles, sides AC and BC are equal. Thus,
7x - 8 = 3x + 4, or
4x = 12. Then x = 3.
Since AC = 7x - 8, and x = 3, AC = 7(3) - 8 = 21 - 8 = 13
