Answer :
Answer:
The answers are [tex]\frac{33}{2} ,10\ and\ \frac{5}{3}[/tex] .
Step-by-step explanation:
Given:
Perimeter is 25.
2x-8
2x+5
30-3x
Now, to solve for [tex]x.[/tex]
So, the first equation to solve:
[tex]2x-8=25[/tex]
Adding both sides by 8 we get:
[tex]2x=33[/tex]
Dividing both sides by 2 we get:
[tex]x=\frac{33}{2}[/tex]
Then, the second equation to be solve:
[tex]2x+5=25[/tex]
Subtracting both sides by 5 we get:
[tex]2x=20[/tex]
Dividing both sides by 2 we get:
[tex]x=10.[/tex]
And, the third equation to solve:
[tex]30-3x=25[/tex]
Subtracting both sides by 30 we get:
[tex]-3x=-5[/tex]
Dividing both sides by -3 we get:
[tex]x=\frac{5}{3}[/tex]
Therefore, the answers are [tex]\frac{33}{2} ,10\ and\ \frac{5}{3}[/tex] .
