E = {1, 2, 3, 4, ... , 10}. F is the set of remainders in the division
by 3 of the
elements of E.
Determine F by using the roster notation.

{1, 2, 3}

Step-by-step explanation:

As we know that n divided by 3 must have a remainder of either 1, 2, or 0 (none).

Thus, it is {1, 2, 0}

Or we can write F = {0, 1, 2}

I hope this helps you :)

12x-17=139

8x+35=139

Step-by-step explanation:

The angles are vertical angles which means they are equal

12x-17 = 8x+35

Subtract 8x from each side

12x -8x-17 = 8x-8x+35

4x -17 = 35

Add 17 to each side

4x - 17 +17 = 35+17

4x = 52

Divide each side by 4

4x/4 = 52/4

x =13

12x-17 = 12(13) -17 = 156-17 =139

8x+35 =8(13) +35=104+35=139
