Answer:
1/9
Step-by-step explanation:
2/3-5/9=6/9-5/9=1/9
On a number line, the coordinates of X, Y, Z, and W are -8, -5, 4 and 6 respectively.
We have to find the length of the segment 
= -5 -(-8)
= -5+8
= 3
Now, we will find the length of the segment 
= 6-4
= 2
Since, the measures of the segments ZW and XY are not equal.
Hence, these segments are not congruent.
Answer:
79
Step-by-step explanation:
We need to calculate the height after 23 months.
so m= 23
Plug in m=23
we have H(m) = 56 + 23 = 79
Answer is 79cm
