34 degrees
The three angles all add up to a straight line, which is 180 degrees. One angle is 56 and one is marked as a right angle, so 90.
56+90+x=180
x=34
Answer:
5f+10x+35
Step-by-step explanation:
5(7+f+2x)
=(5)(7+f+2x)
=(5)(7)+(5)(f)+(5)(2x)
=35+5f+10x
=5f+10x+35

Answer:
-12x+1.50
Step-by-step explanation:
Through Distributing, the above solution is derived
When you are only concerned with the remainder from division by 9, the arithmetic is said to be "modulo 9." The statement "when x is divided by 9, the remainder is 4" can also be written as
 : x mod 9 = 4
When the mod 9 operation is applied to arithmetic involving x, we really only need to apply it to the same arithmetic on the remainder. That is
(2x +2) mod 9 = (2·4 +2) mod 9 = 10 mod 9 = 1
The remainder of 2x+2 divided by 9 is 1.
_____
In the general case, the mod 9 remainder being 4 means that the value of x can be written in general as
x = 9n+4 . . . . for some integer n
Then the expression 2x+2 becomes ...
2(9n+4)+2 = 18n +10 = 9(2n+1) +1
so when we divide this number by 9, we can see the remainder will be 1
