Answer:
x=3 sorry if I am wrong.
Step-by-step explanation:
(5x-2)=(3x+4)
-3 -3
2x-2=4
+2 +2
2x=6/2
x=3

Answer:
>
Step-by-step explanation:
0.90 is closer to 1 and 0.12 is closer to 0; 0 is less than 1, so 0.90 is greater than 0.12 :)
Answer:
Yes
Step-by-step explanation:
Length of the third side
![180-(72+78)=30\ \text{ft}](https://tex.z-dn.net/?f=180-%2872%2B78%29%3D30%5C%20%5Ctext%7Bft%7D)
The hypotenuse is always the longest side of a right triangle.
So, the hypotenuse here is ![c=78\ \text{ft}](https://tex.z-dn.net/?f=c%3D78%5C%20%5Ctext%7Bft%7D)
![a=72\ \text{ft},b=30\ \text{ft}](https://tex.z-dn.net/?f=a%3D72%5C%20%5Ctext%7Bft%7D%2Cb%3D30%5C%20%5Ctext%7Bft%7D)
![c=\sqrt{a^2+b^2}\\\Rightarrow c=\sqrt{72^2+30^2}\\\Rightarrow c=\sqrt{6084}\\\Rightarrow c=78\ \text{ft}](https://tex.z-dn.net/?f=c%3D%5Csqrt%7Ba%5E2%2Bb%5E2%7D%5C%5C%5CRightarrow%20c%3D%5Csqrt%7B72%5E2%2B30%5E2%7D%5C%5C%5CRightarrow%20c%3D%5Csqrt%7B6084%7D%5C%5C%5CRightarrow%20c%3D78%5C%20%5Ctext%7Bft%7D)
The Pythagoras theorem applies so the fence does form a right triangle.
Since he has to give 50, and 12.25*p is the amount of money he has to spend (since it's 12.25 per pizza), we have 50-12.25=change
