Answer:
The height of each step is 1957 yard
Step-by-step explanation:
we are given
Tristan is building steps up to a deck that is 15656 yards above the ground
so, total height =15656 yards
Number of steps =8
now, we can use formula
Height of each step = ( total height)/( number of steps)
now, we can plug these values
and we get
Height of each step is
6=1/5w+7/5w-4 so first, combine like terms
6=8/5w-4 now add the four to both sides
10=8/5w next divide 8/5 on both sides
10/(8/5)=w so
W=6.25
Yes you use the line plot on the right
Answer:
Explanation:
3x - 7y = 21
6x = 14y + 42
Or 6x - 14y = 42
3x - 7y = 21 (1)
6x - 14y = 42 (2)
———————
-2(3x - 7y = 21)
6x - 14y = 42
———————
-6x + 14y = -42
6x - 14y = 42
———————
0x + 0y = 0
So I think in this case x and y has infinitely many solution
