1/4 + 3/10
find the common denominator which is 20
multiply by 5 for 1/4
1(5)/4(5)=5/20
multiply by 2 for 3/10
3(2)/10(2)=6/20
5/20+6/20=11/20
answer:
11/20
I have no idea but I’ll go with 60% cause there’s no picture
Answer: x=15
Explanation: you can set 2x+100 = 5x+55 because they are corresponding interior angles.
Work:
2x+100 = 5x+55
2x+100-5x = 55
2x-5x = 55-100
-3x = -45
divide by -3 to cancel the negative and get x by itself
x = 15
Hope this helped! :)
