El radio de un círculo siempre será la mitad del diámetro. Por lo tanto, si el radio es de 4 pulgadas el doble sería 8 pulgadas.
El diámetro del círculo será de 8 pulgadas.
Answer:

Step-by-step explanation:
25 - 3x = -5(1 - x) - 2x
<u></u>
<u>We have to first get rid of the parenthesis:</u>
==> -5
==> 5x
<u>So now you should have:</u>
25 - 3x = -5 + 5x - 2x
<u>Combine like terms:</u>
25 - 3x = -5 + 5x - 2x
25 - 3x = -5 + 3x
<u>Add 3x to both sides:</u>
25 - 3x = -5 + 3x
+ 3x = + 3x
<u>And you should have:</u>
25 = -5 + 6x
<u></u>
<u>Add 5 to both sides:</u>
25 = -5 + 6x
+5 = +5
30 = 6x
<u>Divide 6 to both sides:</u>
= 
5 = x
Example: 2x + 6 < -8
There's 2 steps to solve this one.
2x + 6 < -8
Subtract 6 from both sides
2x < -14
Divide both sides by 2
x< -7

<u><em>Explanation</em></u>
For making one pizza, amount of cheese needed =
cups =
cups.
Now for finding the total amount of cheese needed to make 10 pizzas, we need to <em>multiply
