Evaluate the following expression 5(1 3)-3(2 -1)

BARSIC [14]

Answer:

Step-by-step explanation:

This problem tests your understanding of order of operations rules.

Here you must do any work inside parentheses first, followed by multiplication, followed by subtraction:

5(13) - 3(2 -1) would be 65 -3(1), or 62.

If you actually meant 5(1 - 3) - 3(2 - 1), then you'd have

5(-2) - 3(1) = -10 - 3 = -13

Please compare the problem you've shared with the original problem, to ensure that these match.

If x/y + y/x = -1 , ( x unequal y, y unequal 0) then the value of x^2 - y^2 is?

Maurinko [17]

Take your original equation $\frac{x}{y} +\frac{y}{x} =-1$

and multiply both sides by $xy$ to remove the fractions. You are left with

$x^2+y^2=-xy$

So, $x^2+y^2=-xy$

Update: There is no numerical answer that can be found without being given a value for either x or y

A sporting goods manager was selling a ski set for a certain price. The manager offered the markdowns shown on the right, making

ra1l [238]

Answer:

The original selling price would be $ 515.87 ( approx )

Step-by-step explanation:

Consider the complete question is :

"A sporting goods store manager was selling a ski set for a certain price. The manager offered the markdowns shown, making the one-day sale price of the ski set $325. Find the original selling price of the ski set. It was marked down 10% and 30%"

Suppose x be the original selling price ( in dollars ),

After marking down 10%,

New selling price = x - 10% of x = x - 0.1x = 0.9x

Again after marking down 30%,

Final selling price = 0.9x - 30% of 0.9x

= 0.9x - 0.3 × 0.9x

= 0.9x - 0.27x

= 0.63x

According to the question,

0.63x = 325

$\implies x =\frac{325}{0.63}=\$ 515.87$

Therefore, the original selling price would be $ 515.87.
