Answer:
X= 9/2
Alternative form
x=4 1/2, x=4.5
Step-by-step explanation:
*= Multiply
1. log (little 10 under) (2)*(3x-1)= log (little 10 under) (2)*(x+8)
2. then divide both side by log (little 10 under (2))
3. 3x-1=x+8
4. move variable to the left side and change its sign
5. 3x-x-1=8
6. then move constant to the right side and change its sign
7. 3x-x=8+1
8. collect like terms
9. 2x=8+1
10. add 8+1
11. 2x=9
12. then divide both sides by 2
13. 2/2 9/2
14. 2/2 cancels out so x=9/2 is the answer
Answer:
I think the answer is Associative.

Answer:
80
Step-by-step explanation:
you have 8 ten times add 8 together ten times you get 80
12,14 to 12,17 is a rise of 3 (14 to 17).
12,14 to 16,14 is a move to the right of 4 (12 to 16)
That means the dimensions of the sandbox are 3ft by 4ft and the perimeter is 2(l+w) or in this case 2 (3+4) or 14 ft
First I would move x and y on the same side so the new equations would be:
y+x=7 and y- (-5x)= 1, then you need to subtract the second equation from the first one
y+x=7
-y- (5x)=1 ,the y value would then be out of the equation leaving you with:
6x=6 then you would divide so
x=1
Then you need to substitute that back into the first equation:
y=(-1) + 7, simplify
y=6 so the final answer is
(1,6)
