Let x= original savings
(x-1,600) - 2/5 (x-1,600) = 1/3x
(x-1,600) - 2/5 + 640 = 1/3x
(3/5)x - 960 = 1/3x
(3/5)x - (1/3)x = 960
(4/15)x = 960
(15/4)(4/15)x = (15/4) 960
x = 15* 240 (960/4 = 240)
x = $3,600 is his original savings
Check:
$3,600 - 1,600 = 2,000
(2/5)($2,000) = $800
2,000 - 800 = 1,200 left over
Answer:
x = 16
Step-by-step explanation:
First, find hypotenuse using 18 and 16.
Using Pythagorean theorem, it gives 24.08
now use it again with the hypotenuse and (36/2) = 18
This gives us x = 16
Step-by-step explanation:
there you go that is how you solve
