7 0

First multiply by 9x. 7 = 378x. Divide each side by 378 to isolate x. 1/54 = x. Check your answer: 7/(1/6) does indeed equal 42.

I'm assuming you meant (7/9)x = 42.

If that's correct, then we can quickly and easily solve for x by multiplying both sides of this equation by 9/7:

(9/7)(7/9)x = (9/7)(42) = 54. x = 54

Answer:

Volume = 66 cm³

Step-by-step explanation:

Area of the oblique triangular prism = Area of the triangular base × Vertical height from the base

From the figure attached,

Area of the triangular base = $\frac{1}{2}(\text{Base})(\text{Height of the right triangle})$

= $\frac{1}{2}(3)(4)$

= 6 cm²

Vertical height of the given oblique prism = 11 cm

Volume of the given oblique prism = 6 × 11

= 66 cm³
