Answer:
The total saving of Alex (a) and Benjamin (b) was 2000$.
=> a + b = 2000 (1)
Alex donates 1/4 of saving, Benjamin donates 1/5 of saving.
Total donation: 440$
=> (1/4)a + (1/5)b = 440 (2)
From (1) and (2):
=>(1/4)(2000 - b) +(1/5)b = 440
=> 500 - (1/4)b + (1/5)b = 440
=> (1/20)b = 60
=> b = 20 x 60 = 1200$ (current balance of Benjamin)
=> a = 2000 - b = 800$ (current balance of Alex)
Hope this helps!

Answer: 1.25664 or if you want in fraction form it's 2π/5
Step-by-step explanation:
To convert degrees to radians, multiply by π /180°
72° ⋅ π/180° = 72π/180 = 2π/5
Therefor, the answer is 2π/ 5 or in decimal form 1.25664.

Answer:
60
Step-by-step explanation:
x = 180 - [ 57 + ( 180 - 117 ) ]
= 180 - [ 57 + 63 ]
= 180 - 120
x = 60
6 with and remainder of 2
we conclude that the inequality can be written as the compound inequality:
m < 8
m > 20
<h3>
</h3><h3>
How to solve the inequality for m?</h3>
Here we have the inequality:
3*|14 - m| > 18
We want to isolate m, so we start by dividing both sides by 3:
|14 - m| > 18/3 = 6
Now we can decompose the inequality in two:
14 - m > 6
14 - m < - 6
Solving both for m, we get:
14 - 6 > m
14 + 6 < m
8 > m
20 < m
Then we conclude that the inequality can be written as the compound inequality:
8 > m
20 < m
