First write the equation 8 + 12 > x because according to the triangle property, the sum of any 2 sides have to be greater than the third side. This means that the difference of any two sides should be smaller than the third side.
So, the answer would be 4 < x < 20.
Answer:
- 4
Step-by-step explanation:
(2*(Rationalize(9.7)-Rationalize(4.8x)))==Rationalize(61.2)-Rationalize(3.4)
Rationalize(18.4)-Rationalize(2.8x)
==Rationalize(57.8)
-Rationalize(2.8x)==Rationalize(57.8)-Rationalize(18.4)
x= 38.4÷-2.8
:x= -4
Step-by-step explanation:
a^2 + 2(b - 6) - 17. a = -7 b = 2
= (-7)^2 - 2(2 - 6) - 17
= 49 - 4 + 12 - 17
= 40
Answer:
Total number of students receiving A grade = 75
Step-by-step explanation:
Total number of students enrolled in elementary algebra this year =300
Percentage of students receiving a grade of A = 25%
To find number of students that will receive a grade of A.
Solution:
In order to find the number of students that will receive a grade of A, we will find the percentage students receiving A grade of the total number of the student.
Number of students receiving A grade = 
⇒ 
Writing 25% as fraction and multiplying.
⇒ 
⇒ 
⇒ 
∴ Total number of students receiving A grade = 75 (Answer)
