i had this answer on my test and if i dont get it right sorry
Answer:
25. a = 60
26. a = 17
Step-by-step explanation:
In these two problems we are going to use a property of parallelograms that says: opposite angles have equal measure
so we have
25.
![6a+10=130\\\\6a=130-10\\\\6a=120\\\\a=60](https://tex.z-dn.net/?f=6a%2B10%3D130%5C%5C%5C%5C6a%3D130-10%5C%5C%5C%5C6a%3D120%5C%5C%5C%5Ca%3D60)
and for 26 we have
![4a-4=2a+30\\\\4a=2a+30+4\\\\4a=2a+34\\\\4a-2a=34\\\\2a=34\\\\a=17](https://tex.z-dn.net/?f=4a-4%3D2a%2B30%5C%5C%5C%5C4a%3D2a%2B30%2B4%5C%5C%5C%5C4a%3D2a%2B34%5C%5C%5C%5C4a-2a%3D34%5C%5C%5C%5C2a%3D34%5C%5C%5C%5Ca%3D17)
Answer:
No, Sorry.
Step-by-step explanation:
Since the bases are different, you'll have to change them even if they have a exponent or not. If you dunno how to make the denominators the same, just multiply the two by eachother.
Example) 1/2 - 3/4
![\frac{1}{2} - \frac{3}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20%20-%20%20%5Cfrac%7B3%7D%7B4%7D%20)
Multiply 2 and 4 together, and then multiply the 4 to the one also. Multiply 2 to four and also to the 3.
![\frac{4}{8} - \frac{6}{8}](https://tex.z-dn.net/?f=%20%5Cfrac%7B4%7D%7B8%7D%20%20-%20%20%5Cfrac%7B6%7D%7B8%7D%20)
The subtract from there.
![\frac{ - 2}{8}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%20-%202%7D%7B8%7D%20)
and then Reduce (if needed.)
![\frac{ - 1}{4}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%20-%201%7D%7B4%7D%20)
I believe you do it like this:
1/2 Q+5/2
divide 1/2 into each term
to divide multiply by the reciprocal
1/2 x2/1= 1
5/2 x 2/1=5
1/2(Q+5)
