There are 28 right handed students in class
<em><u>Solution:</u></em>
Given that, there are 32 students in a class
The ratio of left-handed students to right- handed students is 1 : 7
Let the number of left handed students be 1x
Let the number of right handed students be 7x
<em><u>To find: Number of right handed students in school</u></em>
Total number of students = 32
number of left handed students + number of right handed students = 32
1x + 7x = 32
8x = 32
x = 4
number of right handed students = 7x = 7(4) = 28
There there are 28 right handed students in class
(3x + 2) < -7 or (3x + 2 >7
Explanation/Step by step:
We have| |3x +2| >7
We divide the absolute value inequality into two inequalities
First Inequality (Which is Positive Value)
(3x + 2) >7
Second inequality (Which is the Negative Value)
-(3x + 2) >7
Then you Multiply by- 1 both sides
~And Remember that when you multiply or divide both sides of an inequality by a negative number you must reverse the inequality Symbol.~
So which that be said it would look like this:
(3x +2) < -7
So therefore (3x + 2) < -7 or (3x + 2) >7
Hope this makes since to you!!
I hope this helps as well..
Answer:
Step-by-step explanation:
Trick question. Good to know.
0 is the closest 100.
33 will round to 0
The answer is x=-6
2+(-3x)+(-7)=-x+19
-3x+-5=-x+19
-3x=x+24
-4x=24
x=-6
The answer is x = 2 that's what I think
