1week = 7days so
4weeks = 28 days
So 28 x 640 = 17920
1000grams = 1kg
17920 divide 1000 =17.92
Lee uses 17.92kg in those 4weeks
Using linear pairs,
![115+5x=180\\\\5x=65\\\\x=\boxed{13}](https://tex.z-dn.net/?f=115%2B5x%3D180%5C%5C%5C%5C5x%3D65%5C%5C%5C%5Cx%3D%5Cboxed%7B13%7D)
By the exterior angle theorem,
![2y=45+5(13)\\\\2y=45+65\\\\2y=110\\\\y=\boxed{55}](https://tex.z-dn.net/?f=2y%3D45%2B5%2813%29%5C%5C%5C%5C2y%3D45%2B65%5C%5C%5C%5C2y%3D110%5C%5C%5C%5Cy%3D%5Cboxed%7B55%7D)
I think... J because
x + 1 / x^3 - x
Factor out x from the expression
x + 1 / xx(x^2 - 1)
Use a^2 - b^2 = (a - b)(a + b) to factor the expression
x + 1 / x • (x - 1) • (x + 1)
Reduce the fraction with x+ 1
1 / x • (x - 1)
Distribute x through the parentheses
1 / x^2 - x

Answer:
= 21.6216% decrease
Step-by-step explanation:
Calculate percentage change
from V1 = 29.6 to V2 = 23.2
(V2−V1)|V1|×100
=(23.2−29.6)|29.6|×100
=−6.429.6×100
=−0.216216×100
=−21.6216%change
=21.6216%decrease
