Answer:
4 minus a number times three
Answer:
5/12
Step-by-step explanation:
First you add 1/4+2/3.
You need to change the denominator so that they are equal to each other
If you multiply the 1/4 by 3/3 you will get 3/12 which is equal to 1/4
Then you need to do the same to 2/3. This time you need to multiply it by 4/4 to get the same denominator which will be 2/3*4/4=8/12
Then you add 3/12+8/12=11/12. You don't need to add the denominator.
After this you will need to subtract 11/12 and 1/2. This time you need to only change the denominator for 1/2.
You multiply the denominator and numerator by 6/6 to 1/2 and you will get 6/12 then you are going to subtract 11/12-6/12 and you will get 5/12
Answer:
Step-by-step explanation:
Hint: 1 - Cos² A = Sin² A
1. Is angle 2 and angle 5 are supplementary and the reason is the given
4. The answer is L || M because of the converse of the CIA theorem( corresponding interior angles)
-3 =-2x - 7
Add 7 to both sides
4=-2x
Divide by -2
-2 = x
