tekilochka [14]

The pants cost $36.06 ⇒ answer D

Step-by-step explanation:

George bought a shirt and a pair of pants at a clothing store

1. The pants cost $5.23 more than the shirt

2. He used a $10 off coupon to purchase the shirt

3. The equation s - $10 = $20.83 is used to determine the cost of the

    shirt before the coupon

We need to find the cost of the pants

∵ s represents the cost of the shirt before the coupon

∵ s - 10 = 20.83

- Add 10 to both sides

∴ s = $30.83

The cost of the shirt before the coupon is $30.83

∵ The cost of the pants is $5.23 more than the cost of the shirt

∴ The cost of the pants = the cost of the shirt + $5.23

∵ The cost of the shirt is $30.83

∴ The cost of the pants = 30.83 + 5.23

∴ The cost of the pants = $36.06

The pants cost $36.06

The area of a rectangle is 54cm. The length is 2cm more than a x and the width is 5cm less than twice x. Solve for x. Round your
WITCHER [35]
A rectangle is a quadrilateral and its area is expressed as the product of its length and width. From the given, we have:

Length = x + 2
Width = 2x - 5
Area = 54 cm^2

Area = Length x Width
Substituting the values,
Area = (x + 2) ( 2x-5) = 54
54 = 2x^2 - x - 10
2x^2 - x - 64 = 0

We can see that the equation above is a polynomial with a degree of 2 therefore we can usethe Quadratic Formula to solve for x. The quadratic formula will solve two values of x.

x1 = (-b + (√b^2 - (4ac))/ 2a = 5.91
x2 = <span>(-b - (√b^2 - (4ac))/ 2a = -5.41

Since, for this case, the value x should not result to a negative value  for both dimensions thus x is equal to 5.91.</span>
