4x -6 < -6
I moved the constants over.
4x < 0
Isolate c
x<0
Answer:
8
Step-by-step explanation:
6^7 : 6^6 = 6^(7-6) = 6^1 = 6
3^3 : 3^4 = 3^(3-4) = 3^-1 = 1/3
6* 1/3 = 2
2^3 = 8
Answer:
-16
Step-by-step explanation:
1-2^3-3^2
1-(2)(2)(2)-(3)(3)
1-8-9
-7-9
-16
Answer:
Step-by-step explanation:
3x+y=2............(1)
4y=12-12x........(2)
Making y as subject in (1) and substitute in (2)
y = 2 - 3x......(3)
4(2 - 3x) = 12-12x
8 - 12x = 12 - 12x
12x - 12x = 12- 8
0 = 4
So no solution since variable cancelled out
Answer:
∠ 3 = 25°
Step-by-step explanation:
The sum of the 3 angles 85, 2x and x - 10 are a straight angle = 180°
85 + 2x + x - 10 = 180, that is
3x + 75 = 180 ( subtract 75 from both sides )
3x = 105 ( divide both sides by 3 )
x = 35
Thus x - 10 = 35 - 10 = 25
∠ 3 and x - 10 are Alternate angles and congruent, thus
∠ 3 = 25°
