Answer:
![-452 \frac{6}{7}](https://tex.z-dn.net/?f=-452%20%5Cfrac%7B6%7D%7B7%7D)
Step-by-step explanation:
You just subtract the new elevation from the original, ![-355 \frac{2}{7} - 97 \frac{4}{7} = -452 \frac{6}{7}](https://tex.z-dn.net/?f=-355%20%5Cfrac%7B2%7D%7B7%7D%20-%2097%20%5Cfrac%7B4%7D%7B7%7D%20%3D%20-452%20%5Cfrac%7B6%7D%7B7%7D)
Answer:
256
Step-by-step explanation:
since the the path surounds both sides of the garden you have to add 2 x instead of just x
let me show you what i mean. 10=garden width and 3=path width=x
since it is a square, we can calculate the area by taking one side and squaring it so you get (10+2x)^2 which is 16^2 since x is 3, the width of the garden
to do simaler problems just use thei formula (garden length+2path length)^2 or (garden length+2path length)times(garden length+2path length)
Answer:
R = 20
Step-by-step explanation:
mean age = sum of ages/no. of men
sum of ages of the men that left = 55 + 63 = 188
remaining sum = 50R - 118
remaining no. of men = R - 2
now mean age = 50 - 1 = 49 years
49 = 50R-118/R-2
49(R - 2) = 50R - 118
49R - 50R = -188 - 98
-R = -20
R = 20
