Step-by-step explanation:
A) 3x + 8 = 23
3x = 23 - 8
3x = 15
x = 15 / 3 = 5
B) 5x + 1 = 3x + 17
5x - 3x = 17 - 1
2x = 16
x = 16 /2 = 8
C) 4 (x+2) = 32
4x + 8 = 32
4x = 32 - 8
4x = 24
x = 24 / 4 = 6
C is the answer to this question.
Answer:
all answers below
Step-by-step explanation:
(i) 2704 = 2^4 x 13^2
(ii) as both indices (the powers) are divisible by 2, it is a perfect square.
(iii) as both indices are not divisible by 3, it is not a perfect square.
Answer:
-4(8-3x)>or =6x-8
Step-by-step explanation:
open d bracket
-32+12x >or = 6x-8
collect like terms
12x-6x >or =-8+32
6x = 24
divide both sides by 6
x= 4
Angle 2 = 46°
Angle 3 = 180-46=134°
