Its alot of long division, but the answer is 217.625.
Let the number be x.
7x-x=42
6x=42
x=7
the number is 7
X-1= 5x+3x-8
Combine like terms
x-1= 8x-8
Our goal is to isolate x by cancelling out other numbers.
Subtract x from both sides
x-1-x= 8x-x-8
-1= 7x-8
Add 8 to both sides
7=7x
Divide both sides by 7
1=x
Final answer: x=1
Answer:
1, , .
Step-by-step explanation:
probability =
Total number of persons in the party = n
a) Pr ( every person gets their phone back) = Pr (each person picks his phone ) multiplied by number of person
= × n = 1.
No of first m persons to pick = m
No of last m persons to pick = 1 - m
b) Pr (first m persons to pick each gets their phones back) =
c) Pr( first m persons get a phone belonging to last m persons) =
Answer:
<h3>D. The amount of rotation of one side.</h3>
Step-by-step explanation:
We need to explain the statement " What affects the size of an angle? ".
Given options are

B. The direction of one side
C. Its orientation in space
D. The amount of rotation of one side.
The correct option would be :
<h3>D. The amount of rotation of one side.</h3>
<em>Because as the one side rotated, it makes a greater or smaller arc between the two lines. That would affects the size of an angle. </em>
