Answer:
1 y=-1/10x
2 y=-x-8
3 y= 7/3x or 2 1/3x
Step-by-step explanation:
1 -x=10y
divide -x and 10 by 10
2 y+8=-x
subtract 8
3 -4+7x+4=3y
divide everything by 3

Answer:
2520 patterns
Step-by-step explanation:
In 'n' 10! ways, books can be arranged. But, there are also 5! permutation of blue books 'n1', 2! permutation of identical green books 'n2', and 3! permutation identical black books 'n3'.
Therefore, for non identical arrangements:

= 2520
Therefore, the books can be arranged on a shelf in 2520 patterns
Answer:
126
Step-by-step explanation:
Let x be the missing length
The triangles are similar:
● UE/140 = 45/x
From the graph we deduce that:
● UE = 140 - 90 = 50
Replace UE by its value
● 50/ 140 = 45/x
Switch x and 50
● x / 140 = 45/50
45/50 is 9/10 wich is 0.9
● x/140 = 0.9
Multiply 0.9 by 140
● x = 140 × 0.9
● x = 126
-12/4= -3
18/5= 3.6
-2.5= -2.5
1/5= .2
10= 10
Ordered) -12/4, -2.5, 1/5, -2.5, 10
The median is 1/5 since it's in the middle of all five numbers.
Hope I could help! :)
