0.7x+6=0.3(4x+6)−2x
Gelneren [198K]

Answer: x=-2.8

Step-by-step explanation:

Given the following equation:

0.7x+6=0.3(4x+6)-2x

You can follow these steps in order to solve for "x" and find its value:

1. Apply Distributive property on the right side of the equation:

0.7x+6=0.3(4x+6)-2x\\\\0.7x+6=1.2x+1.8-2x

2. Subract 0.7x from both sides and add the like terms:

0.7x+6-(0.7x)=1.2x+1.8-2x-(0.7x)\\\\6=-1.5x+1.8

3. Subtract 1.8 from both sides:

6-(1.8)=-1.5x+1.8-(1.8)\\\\4.2=-1.5x

4. Finally, divide both side of the equation by -1.5:

\frac{4.2}{-1.5}=\frac{-1.5x}{-1.5}\\\\x=-2.8

Find the perimeter and the area of a rectangle with the sides 4 7/20 m and 6 2/3 m.
Simora [160]

9514 1404 393

Answer:

  • perimeter: 22 1/30 m
  • area: 29 m²

Step-by-step explanation:

The perimeter is given by the formula ...

  P = 2(L+W)

  P = 2(4 7/20 +6 2/3) = 2(10 +61/60) = 2(11 1/60)

  P = 22 1/30 . . . . meters

__

The area is given by the formula ...

  A = LW

  A = (4 7/20)(6 2/3) = (87/20)(20/3) = 87/3 = 29 . . . . square meters

The perimeter is 22 1/30 meters; the area is 29 square meters.
