A store sells televisions for $360 and DVD burners for $270. The entire stock is worth $52,920 and there are a total of 164 tele

bogdanovich [222]

Answer: 96 Televisions, 68 DVD burners

Step-by-step explanation:

Let T represent the quantity of televisions

Let D represent the quantity of DVD burners

Given:

value of television (T) = 360

value of DVD burners (D) = 270

Total value = 52,920

Equations:

Value: 360T + 270D = 52,920

Quantity: T + D = 164

We can solve the system of equations using the Elimination Method:

-1(360T + 270D = 52,920) → -360T - 270D = -52,920

360(T + D = 164) → 360T + 360D = 59,040

90D = 6,120

÷90 ÷90

D = 68

Input the value of D into one of the equations to solve for T

T + D = 164

T + 68 = 164

T = 96

The equation 22 = 2y + x represents the perimeter of a flower garden with

iren [92.7K]

Answer:

$y = \frac{22-x}{2}$

For width = 2 ft, the length of the flower bed = 10 ft.

For width = 3 ft, the length of the flower bed = 9.5 ft.

For width = 4 ft, the length of the flower bed = 9 ft.

Step-by-step explanation:

Here, the Perimeter of the flower garden is given as

22 = 2 y + x

: where, y : Length of the garden

and x : Width of the garden .

Now, solving for y in the above expression,we get

22 = 2 y + x ⇒ 22 - x = 2 y

or, $y = \frac{22-x}{2}$

Now, when the width (x) = 2 feet

Length of the flower bed $y = \frac{22-x}{2} = \frac{22-2}{2} = \frac{20}{2} = 10$

or, x = 10 ft

⇒For, the width = 2 ft, the length of the flower bed = 10 ft.

when the width (x) = 3 feet

Length of the flower bed $y = \frac{22-x}{2} = \frac{22-3}{2} = \frac{19}{2} = 9.5$

or, x = 9.5 ft

⇒For, the width = 3 ft, the length of the flower bed = 9.5 ft.

when the width (x) = 4 feet

Length of the flower bed $y = \frac{22-x}{2} = \frac{22-4}{2} = \frac{18}{2} = 9$

or, x = 9 ft

⇒For, the width = 4 ft, the length of the flower bed = 9 ft.
