I dont know if this is right but the answer to 2(12+8x)-3(4x-9) might be 4x+51?
Answer:
d
Step-by-step explanation:
The first thing you should do is solve the equation yourself.
1) Distribute the 2.
6x + 4 = 2x – 16
2) Next, you'll want to get the x's on one side. So add -2x to both sides.
6x + 4 + -2x = 2x + -2x - 16
4x + 4 = -16
3) Now subtract 4 from both sides
4x + 4 – 4 = -16 – 4
4x = -12
4) Finally, divide both sides by 4
4x/4 = -12/4
x = –3
To solve this problem all you need to do is look back out you work, and figure out the correct solution. The answer the question is The student made an error in Step 1.
Interior angle+exterior angle=180
10x +10 +3x -12 =180
13x-2=180
13X+182
X=14 sides
Answer:
99 robberies
Step-by-step explanation:
What you are basically doing is taking the discount.
1 + 14% = 1.14
