Two siblings ' ages have a sum of 64 years . The older sibling was born 6 years before their young sibling . Write a system of 2

ELEN [110]

Answer:

younger sibling = 29 years

older sibling = 35 years

Step-by-step explanation:

Let

x = younger sibling

y = older sibling

x + y = 64 (1)

The older sibling was born 6 years before their young sibling

x = y - 6 (2)

Substitute x = y - 6 into (1)

x + y = 64

y - 6 + y = 64

2y = 64 + 6

2y = 70

y = 70/2

y = 35 years

Substitute y = 35 into (2)

x = y - 6

x = 35 - 6

x = 29 years

A home theater system is marked down from $3999 to $3180. What is the discount, and what is the rate of discount? (Round to the

Margarita [4]

Answer: The required discount is $819 and the rate of discount is 20.48%.

Step-by-step explanation: Given that a home theater system is marked down from $3999 to $3180.

We are to find the discount and the rate of discount.

The discount will be given by actual price minus the marked price.

We have

Actual price = $ 3999 and marked price = $3180.

So, the discount is given by

$\textup{Discount}=\$(3999-3180)=\$819$

And the rate of discount is

$\textup{Rate of discount}=\dfrac{819}{3999}\times100\%=20.48\%$

Thus, the required discount is $819 and the rate of discount is 20.48%.
