Answer:
Find out the numbers .
To prove
Let us assume that one number be x.
Let us assume that second number be y.
As given
The sum of two numbers is 30.
Than the equation becomes
x + y = 30
Their difference is 6.
x - y = 6
Thus two equation are .
x + y = 30 and x - y = 6
Subtracted x - y = 6 from x + y = 30
x - x + y - (-y) = 30 - 6
y + y = 24
2y = 24
y = 12
Put in the x - y = 6
x - 12 = 6
x = 6 + 12
x = 18
Therefore the two numbers are 12 and 18 .

Answer:
The value of the investment by the end of the month is $59.89.
Percent loss = 20% to the nearest tenth
Step-by-step explanation:
At the end of the month, there was a loss of $13.53 from the $73.42 investment at the beginning of the month.
Value in Dollars = $73.42 - $13.53
= $59.89
The value of the investment by the end of the month is $59.89.
PERCENTAGE LOSS =
(CP - SP / CP ) * 100
= ($73.42 - $59.89 / $73.42) * 100
= ($13.53 / $73.42) * 100
= 0.184 * 100
= 18.43%
= 20% to the nearest tenth
Enjoy! Maths is fun
