Option D:
Solution:
Given compound inequality:
Let us first solve .
Subtract 6 from both sides.
To reverse the inequality multiply by -1 on both sides.
Now solve the next inequality .
Add 9 on both sides.
Divide by 2 on both sides.
Combine the inequality.
Option D is the correct answer.
1 times something is the same number
so
make bottom 1
3/4 times 4/3=12/12=1 so
times wole thing by
result
=
=
=8
basically
a/b divided by c/d=a/b times d/c, invert and multiply
Let's evaluate left side first.
There are 4 -5's and 5 -3's
So that's 4(-5) + 5(-3) = -35
So now our equation is -35 = -5x
Now divide both sides by -5:
-35 / -5 = x
7 = x
So the missing number would be 7 to make this equation true.
Final answer: 7
Hope this helps.
So Area = length x width
Area = 450, width = 9
450 = 9 x length
divide 450 by 9, and you have the length.
Perimeter = length + length+ 9 + 9
and you got your perimeter!
2/3 to nearest thousandth = 0.667
