Let's assume you're solving for x
Your equation:
17 - 5 (2x - 9) = -(-6x + 10) + 4
Distribute the -5 and the -
-5 · 2x ; -5 · -9
Simplify
-10x + 45
Let's put a 1 by the negative sign, it can help you multiply easier.
-1 · -6x ; -1 · 10
Simplify
6x - 10
Simplify
17 - 10x + 45 = 6x - 10 + 4
Combine like terms
17 + 45 = 62 ; -10 + 4 = -6
Simplify
62 - 10x = 6x - 6
Distribute the x terms to one side, try and get rid of negative numbers.
62 - 10x + 10x = 6x + 10x - 6
Simplify
62 = 16x - 6
Add the 6 to the other side.
62 + 6= 16x - 6 + 6
Simplify
70 = 16x
Get x all by itself ; divide by 16
70/16 = 16x/16
4.375 = x
I hope I helped! If you have any questions, ask me. And help me out by marking Brainliest on my answer if I did really well!
Ответ:
Student B is correct.
Step-by-step explanation:
To construct a parallel line following steps should be followed,
1). Draw a line that intersects at B and C.
2). Place a compass at point B and swing an arc that crosses line AB and BC.
Label the points D and E.
3). Keep the compass at the same width and place it on point C.
4). Swing an arc that crosses line BC at F.
5). Open the compass to the width between points D and E.
6). Keeping the compass at the same width, place it on point F.
7). Swing an arc that intersect the arc created from line BC at point C.
8). Mark the intersection of two arcs as point G.
9). Draw a line through point C and G.
Student B is correct.
