Im pretty sure the first piece is 9 and then 9 x 3 = 27 and then 9 x 5 is 45 so piece on is 9 piece 2 is 27 and piece 3 is 45 :)
Answer: 64<em>% were girls</em>
Step-by-step explanation:
<em>Add 320 with 180</em>
<em>320+180=500</em>
<em>take 500 and divide it by 320</em>
<em>320/500 = 64</em><em>%</em>
Answer:
x = 2
Step-by-step explanation:
1 - 3x = -5
Subtract 1 from each side
1-3x-1 = -5-1
-3x = -6
Divide each side by -3
-3x/-3 = -6/-3
x = 2
V = 24/3 = 8
So v = 8
Hope this helps, if it is , pls brainliest !!

Answer: 16 miles</h3>
==========================================================
Explanation:
x = time in hours spent going upstream
5-x = remaining time in hours spent going downstream
Those two quantities add to 5 hours total.
Let's find the expression for how far the fisherman went upstream
distance = rate*time
d = r*t
d = 2x
Do the same for the downstream portion
d = r*t
d = 8(5-x)
d = 40-8x
The values of d refer to the same distance because he came back to the starting point.
Set those right hand sides equal to one another and solve for x.
2x = 40-8x
2x+8x = 40
10x = 40
x = 40/10
x = 4
5-x = 5-4 = 1
He spent 4 hours going upstream, and the remaining 1 hour coming back downstream.
--------------
If he spent 4 hours going upstream at 2 mph, then he traveled d = r*t = 2*4 = 8 miles.
The remaining 1 hour going downstream at 8 mph means he traveled d = r*t = 8*1 = 8 miles, which matches with the previous result. This confirms we have the correct one-way distance of 8 miles.
Therefore, the total round trip distance is 2*8 = 16 miles
