1/3 = 2/6 = 3/9 = 4/12 = 5/15 = 6/18 = 7/21 = 8/24 = 9/27 = 10/30 = 11/33 = 12/36 = 13/39 = 14/42 = 15/45 = 16/48 = 17/51 = 18/54 = 19/57 = 20/60
You can use any, these are just the smallest to the biggest but any are fine but I would use the first one. Hope I helped. Equivalent is what 3/9 equals to.
5n + 7 = 7(n+1) - 2n
First distribute 7 to all terms inside the parenthesis
7(n) = 7n
7(1) = 7
5n + 7 = 7n - 2n + 7
Simplify. Combine like terms
5n + 7 = 5n + 7
True.
If you want to continue:
Isolate the n, move all variables to one side, and constants to the other
5n (-5n) + 7 (-7) = 5n (-5n) + 7 (-7)
0 = 0
True
hope this helps
Answer:
y = -4x+4
Step-by-step explanation:
Pick two points on the line
(0,4) and (1,0)
We can find the slope
m = (y2-y1)/(x2-x1)
= (0-4)/(1-0)
= -4/1 =-4
We know the y intercept is 4
The slope intercept form of the equation is y = mx+b where m is the slope and b is the y intercept
y = -4x+4
Answer:
FG = 15
Step-by-step explanation:
Note that
EF + FG = EG ← substitute values into equation, that is
6 + FG = 21 ( subtract 6 from both sides )
FG = 21 - 6 = 15
212= 2 X 2 X 53
212= 4X 53
