Answer:
15;9;-8
Step-by-step explanation:
1. 5/3x-3=2/3x+12
x=15 once you combine like terms
2. 5x+35-3x+12=7x+2
2x+47=7x+2
5x=45
x=9
3. 12x+20-3=9x-7
12x+17=9x-7
3x=-24
x=-8
You're looking for c, so you want to isolate it or get it by itself. To get rid of the /3 you multiply since the opposite of division is multiplication and to get rid of it, you do the opposite (like -9 you would add 9 to get it to 0). Now you are left with -19+c = 24 (the 24 is 8*3 because what you do to one side you do to the other. Now you get c by itself so you add 19 to both sides which leaves you with C= 43. Sorry if this was confusing!
Answer:
3/14
Step-by-step explanation:
6/7 ÷ 4
Copy dot flip
6/7 * 1/4
Rewriting
6/4 * 1/7
Divide the top and the bottom of the first fraction by 2
3/2 * 1/7
3/14
1 2/3 . Hope this helps ;)
X²+y² =(Radius)²
x²+y² =10². So the radius is 10
