Answer:
60.
Step-by-step explanation:
I guess you mean the LCM (Lowest Common Multiple):
12 = 2 * 2 * 3
30 = 2 * 3 * 5
We see there are duplicate 2's and 3's so:
So the LCM is 2 * 2 * 3 * 5 = 60.
(the duplicates only appear once in the calculation).
The answer is D for 4x +7x equals 11x and 12 is a number that doesn't have an x and you must combine like terms so the answer is D.
Answer:
Co-interior angels adds up to 180
180-109=71
? Is 71
2x + x + 45=180
3x + 45 =180
- 45
3x =135
÷3
x=45
2x = 90
So, 90+45+45=180
x =45
B
Answer:
