You have to start by adding 4/5 in order to get x alone. When you add 4/5 and 6/13, you have to find the smallest number that both the fractions can have as the same number in the denominator. For this case it is 5 because 13 times two, three, or four won't equal a number that 5 times any whole number can equal. 13 times 5 is 65 and 6 times 5 is 30 so our new fraction is 30/65. For 4/5 we do the same. In order for the bottom number to equal 65, you have to multiple the fraction by 13. 5 times 13 is 65 and 4 times 13 is 52 so our new fraction is 52/65. We now add 52/65 and 30/65 to get 82/65!

Answer:
x = 45
Step-by-step explanation:
The two angles form a right angle, which means their sum is 90 degrees
x+45 = 90
Subtract 45 from each side
45+x-45 = 90-45
x = 45
1)x=3
2)m=1 4/5
3)M= - 11
4)X=7 1 1/2
5) i dont know this one sorry
i hope this is enough it took long and i skipped half of my class <3
