Answer:
p = 13
Step-by-step explanation:
Step 1: Write equation
16p = 208
Step 2: Solve for <em>p</em>
- Divide both sides by 16: p = 13
Step 3: Check
<em>Plug in p to verify it's a solution.</em>
16(13) = 208
208 = 208
Answer:
w = 13yd, l = 18yd
Step-by-step explanation:
let x be width, so x+5 = length
Perimeter is sum of all 4 sides, and since opposite sides equal in rectangle,
P = 2(l+w)
= 2(x+5 +x)
= 4x + 10
Since perimeter is give as 62yd, equation is
4x + 10 = 62
4x = 52
x = 13
Answer:
i think it's 37.7
Step-by-step explanation:
Answer:
Step-by-step explanation:
← Equation 1
By simplifying the above equation we get,
(Simplifying the brackets)
(By subtracting 
from 
) ← Equation 2
Multiply Equation 1 by 5 and Equation 2 by 3 and add them together.
Equation 1 multiplied by 5 will give,
Equation 2 multiplied by 3 will give,
Add those together,
(After simplifying 
values)
Therefor
By substituting to Equation 1 we get,
Therefor we can say,
Without the actually predicted values in comparison to the real values it is only possible to give a very likely answer based on their scale:
a) is 25 million off, which sounds bad but when compared to a few billion in population it's not even 1%
b)3 billion is more than half the world population as error: very unlikely
c)154 billion, unlikely that a prediction is off by a factor of ~30
d)same as c
so a) is most likely the solution, but in theory the predictions could be arbitrarily bad (things like negative population, or extreme growths)
