Answer:

otterbox costs $95; beats costs $210

Step-by-step explanation:

x = otterbox   y = beats

4x + 2y = 800      y = 2x + 20

4x + 2(2x + 20) = 800

4x + 4x +40 = 800

8x + 40 = 800

8x = 800 - 40

8x = 760

x = 760 / 8

x = 95  Otterbox costs $95 each


4x + 2y = 800

4(95) + 2y = 800

380 + 2y = 800

2y = 800 - 380

2y = 420

y = 420 / 2

y = 210   Beats costs $210


4(95) + 2(210) = 800

380 + 420 = 800

Answer:

Otterbox = $95

Beats = $210

Step-by-step explanation:

Let's take o for Otterbox and b for Beats.

4 o + 2 b = $800

b = 2 o +$20

So,  4 o + 2 b = $800 => 8 o + $40  = $800

Therefore,

Otterbox = $95

Beats = $210

Answer:

49.5 mi

Step-by-step explanation:

Area of a triangle is   A = (height) X (base) / 2

So if you plug in the numbers you get:

806.9 = (32.6) X (base) / 2

1613.8 = (32.6) X (base)

1613.8 / 32.6 = base

base =  49.5 mi

2x=10

divide both sides by 2 2x/2=10/2
