Answer: It is common that your eyes are not green
<u>Step-by-step explanation:</u>
Given an "if p, then q" statement (notation: p → q)
the contrapositive is " if not q, then not p" (notation: ~q → ~p)
In the given statement,
- p = your eyes are green
- q = it is not common
So,
- ~p = your eyes are not green
- ~q = it is common
Therefore, the contrapositive should be:
If <u>it is common </u>, then <u>your eyes are not green</u>.
But grammatically it sounds better to say,
"It is common that your eyes are not green"
1.1x+1.2x-5.4=-10x
Move all terms to the left:
1.1x+1.2x-5.4-(-10x)=0
Add all the numbers together, and all the variables
2.3x-(-10x)-5.4=0
Get rid of parentheses
2.3x+10x-5.4=0
Add all the numbers together, and all the variables
12.3x-5.4=0
Move all terms containing x to the left, all other terms to the right
12.3x=5.4
x=5.4/12.3
x=3.8571428571429/8.7857142857143

Let’s let s = sale price per package
r = =regular price per package
c = cost savings.
Answer: c= 3r – 3s
Another way to do it is
2x-y=17
x-y=10, x=10+y
substitute x=10+y for x in 2x-y=17 and get
2(10+y)-y=17
20+2y-y=17
20+y=17
subtract 20 from both sides
y=-3
subsitute y=-3 into equation x-y=10
x-(-3)=10
x+3=10
subtract 3 from both sides
x=7
or subsitute into 2x-y=17
2x-(-3)=17
2x+3=17
subtract 3 from both sides
2x=14
divide both sides by two
x=7
