Let n be a number of balls: n = 14
In one pan you have 8 balls: 8n
In the other pan you have the rest of balls (14 - 8 = 6) along with a <span>weight of 20 grams = 6n + 20
So the pans are balanced:
8n = 6n + 20
Now, just solve the equation:
8n - 6n = 20
2n = 20
n = 20/2
n = 10
So, you know that a ball weights 10 grams.</span>
First you take 15/10 and see that you can take 5 out of the top and bottom, so it would become 3/2. Now you have 2 3/2. 2 goes into 3 once with 1 remainder so 3/2= 1 1/2
So then you take the original 2 and add it to 1 1/2. The answer is now 3 1/2
I can't really help without the amounts being given but I can say that two supplementary angles add up to 180 degrees, so I hope that helps
Answer:
p = 1
Step-by-step explanation:
-6p - 21 = 3p - 12
+6p +6p
-21 = 9p - 12
+12 +12
9 = 9p
//////////
9 9
1 = p
p = 1
