If 5x=-20 then it would be
adding 2 and subtracting 2 they cancel out so its
and if you subtract 2 from negative 18 it is negative 20 so it is true
Answer:
x=-24 & x=4.
Step-by-step explanation:
-5/6x=20
x=20/(-5/6)
x=(20/1)(-6/5)=-120/5=-24
-------------------------------------
2/3(x-7)=-2
2/3x-14/3=-2
2/3x=-2+14/3
2/3x=-6/3+14/3
2/3x=8/3
x=(8/3)/(2/3)
x=(8/3)(3/2)=8/2=4
Based on the data displayed in the histogram, the percentage of students who study 2 or more hours for the midterm is 88%.
<h3>What percentage study 2 hours or more?</h3>
First, find the number of students studying:
= 3 + 9 + 6 + 3 + 2 + 1 + 1
= 25
The number of students studying 2 or more hours for the exam are:
= 9 + 6 + 3 + 2 + 1 + 1
= 22 students
The percentage studying for two hours or more is:
= 22 / 25
= 88%
