Answer:

$-0.2(x - 4) = - 1.7$

$-0.2x + 0.8 = - 1.7$

$-0.2x = - 2.5$

$x = 12.5$

Step-by-step explanation:

Solving $-0.2(x - 4) = - 1.7$ using the distributive property:

$(-0.2)(x) + (-0.2)(-4) = - 1.7$

$-0.2x + 0.8 = - 1.7$

Subtract 0.8 from both sides

$-0.2x + 0.8 - 0.8 = - 1.7 - 0.8$

$-0.2x = - 2.5$

Divide both sides by -0.2

$\frac{-0.2x}{-0.2} = \frac{-2.5}{-0.2}$

$x = 12.5$

Find the volume of a pyramid with a square base, where the perimeter of the base is 8.6 cm and the height of the pyramid is 8.1

Ymorist [56]

Answer: 12.5 CC

Step-by-step explanation:

V=1/3Bh where B is the area of the base and h is the height

The perimeter of the square base is 8.6 so each side is 2.15 and the area of the base is (2.15)^2 or 4.6225

V=1/3(4.6225)(8.1)=12.5cc
