That looks very hard, keep trying with the steps so yeah
Answer:
Number n increased by 18 = n +18
Number is 2 less than 5 times n= 5n -2
They are same => n +18 = 5n -2
Option B
[ n + 18 = 5n -2
18 +2 =5n - n
20 = 4n
n = 5
Lets check 5+18 = 5*5 - 2
23 = 23]
She would save 256.4 because 1.79×160=286.4 and then 286.4 - 30=256.4

Answer:
1/2, 1/4
Step-by-step explanation:
Let the numbers be x and y.
Given, x=2y
1/x + 1/y = 6
plug in x=2y ,
1/2y+1/y = 6
Taking common denominator ,
(1+2)/2y = 6
2y = 3/6 = 1/2 => y=1/4
x = 2y = 2* 1/4 = 1/2
So, the numbers are 1/2 and 1/4
