Answer:
2x + 6
2 times the number x is 2x (2 times x)
six more than that would be +6
Answer:
the value of m = 28°
Step-by-step explanation:
the sum of adjacent angles which form linear pair is 180°
so,
=》3m - 6° + 3m + 18° = 180°
=》6m + 12° = 180°
=》6m = 180° - 12°
=》m = 168° ÷ 6
=》m = 28°
x = 30
The distributive property says that we need to multiply what's in the brackets by 1/2 (so 1/2*x and 1/2*6) to get the equation 1/2x + 3 = 18.
Then we need to subtract our constant, 3, from boths sides to get 1/2x = 15.
Multiply both sides by two to isolate x and you get x = 30.
Hope this helps! :)
