Answer:
Option C) 2=2 is the last step of Naomi and it is the correct answer
Step-by-step explanation:
Given that Naomi solves a system of equation by Substitution method :
The given system has infinite many solutions
Naomi's last step is 2=2
<h3>For : A system of equations after solved then its constant value must be same in both the sides</h3>
Then the system of equations has infinite many solutions
Therefore it must be 2=2
Hence option C) 2=2 is the last step and it is the correct answer
Answer:
55.13%
Step-by-step explanation:
Your comparison is 215 men out of 390 people.
Divide 215 by 390 and then multiply by 100 to get your percentage
215 ÷ 390 = 0.5513
0.5513 × 100 = 55.13%
Law = 99 sq.
L = 2w + 7
---
Law = 99
(2w + 7)w = 99
2ww + 7w = 99
2ww + 7w - 99 = 0
---
the above quadratic equation is in standard form, with a=2, b=7, and c=-99
---
to solve the quadratic equation, plug this:
2 7 -99
the roots of the quadratic are:
-9
5.5
---
the negative root doesn't make sense as a length, so use the positive root:
---
w = 5.5
L = 18
