Ilia_Sergeevich [38]

D is answer.
Perimeter is 2x +3x +2x + 3x = 10x where x is unknown factor of distance.
So P = 10x
Velocity is 12 km/hr = .2 km/min
P =1.6 Km = 10x
x= .16 Km 3x = .48 km, 2x=.32 km
Area = .48 X .32 Km^2
= 153600 m^2

2[3x-(4x-6)]=5(x-6) Solve and answer the linear equation.

OleMash [197]

Answer: x = 6

Step-by-step explanation:

2[3x - (4x - 6)] = 5(x - 6)

2[3x - 4x + 6] = 5x - 30

2[-x + 6] = 5x - 30

-2x + 12 = 5x - 30

+2x +2x

12 = 7x - 30

+30 +30

42 = 7x

$\frac{42}{7} = \frac{7x}{7}$

The perimeter of an isosceles trapezoid is 28 in and the ratio of lengths of its bases is 5:3. Find the lengths of the sides of

Natalka [10]

The measurements are:
b₁ = 8.4 inches; b₂ = 14 inches; leg₁ = 2.8 inches; leg₂ = 2.8 inches

Let x = length of base and leg

The formula for perimeter of isosceles trapezoid is P = b₁ + b₂ + 2(leg)
Where: b = base

   P = b₁ + b₂ + 2(leg)
   28 = 3x + 5x + 2(x)
   28 = 8x + 2x
28/10 = 10x/10
2.8 = x

Now, substitute the values:
     P = b₁ + b₂ + 2(leg)
   28 = 3(2.8) + 5(2.8) + 2(2.8)
28 = 8.4 + 14 + 5.6
28 = 28

Hence the measurements are:
b₁ = 8.4 inches; b₂ = 14 inches; leg₁ = 2.8 inches; leg₂ = 2.8 inches
