Answer:
x = 2x
x + 20 = 2x + 20
And,
1.5(x + 20) = 2x + 20
x = 20 i.e. Alexis
And, Jelani be 40
Step-by-step explanation:
Given that
Jelani has twice as much as Alexis
And, both can added $20
Jelani will have 1.5 times as much on his pass on Alexis
We need to write an equation also the amount does Jelani and Alexis have
So,
Let us assume the alexis be x
And, Jelani be 2x
Now
x = 2x
x + 20 = 2x + 20
And,
1.5(x + 20) = 2x + 20
1.5x + 30 = 2x + 20
-0.5x = -10
x = 20 i.e. Alexis
And, Jelani be 40
You have to use the equation (72+y)=5(4+y) which Y =+13

Answer:
Option D) 1.26 tons
Step-by-step explanation:
we have
![d=\frac{10w}{\pi}](https://tex.z-dn.net/?f=d%3D%5Cfrac%7B10w%7D%7B%5Cpi%7D)
where
d is the diameter of a rope in inches
w is the weight in tons
we have
----> the diameter is two times the radius
substitute the value of d and solve for w
![4=\frac{10w}{\pi}](https://tex.z-dn.net/?f=4%3D%5Cfrac%7B10w%7D%7B%5Cpi%7D)
![w=\frac{4\pi}{10}=0.4\pi\ tons](https://tex.z-dn.net/?f=w%3D%5Cfrac%7B4%5Cpi%7D%7B10%7D%3D0.4%5Cpi%5C%20tons)
assume
![\pi =3.14](https://tex.z-dn.net/?f=%5Cpi%20%3D3.14)
![0.4(3.14)=1.26\ tons](https://tex.z-dn.net/?f=0.4%283.14%29%3D1.26%5C%20tons)
