Answer:
The inequality is 
Step-by-step explanation:
Given : The isosceles triangle with base and side 4x+3, 2x+7.
And the perimeter is at least 137ft.
To write : An inequality for x
Solution : Let the base
and sides 
The perimeter of Isosceles triangle is 
where s=side and b=base
Now, we have given that perimeter is at least 137 ft.
Therefore, the inequality form is



Answer:
x=27
Step-by-step explanation:
-4x+4=-3x+31
4=x+31
27=x
Replace each occurrence of x by 7. So we have:-
7^2 + 3 / 7 - 9
= 52 / -2
= -26 answer
Answer:
<em>Martin saved $75 on the television because of the sale</em>
Step-by-step explanation:
<u>Equations</u>
Let's call x=the original price of the television (before discount).
The television had been on sale for 25% off, this means the discount was:
25% of x =
= 0.25x
The sale price was the original price minus the discount:
x - 0.25x = 0.75x
This is what Martin paid, thus:
0.75x = 225
Dividing by 0.75:
x = 225 / 0.75
x = $300
The original price of the television was $300, and the discount was:
0.25*$300 = $75
Martin saved $75 on the television because of the sale
Attached the solution and work. I think this is what you asked for.
