Simplify (4x-8)/(-3x)*(12)/(12-6x)

zloy xaker [14]

$\dfrac{4x-8}{-3x}\cdot\dfrac{12}{12-6x}=\dfrac{4(x-2)}{-x}\cdot\dfrac{4}{-6(x-2)}=\dfrac{4}{-x}\cdot\dfrac{4}{-6}\\\\=\dfrac{2}{-x}\cdot\dfrac{4}{-3}=\dfrac{(2)(4)}{(-x)(-3)}=\dfrac{8}{3x}$

Find the value of x and y. y=2x and 1.85x+3.7y=12.95

Len [333]

Answer:

x=1.4 y=2.8

Step-by-step explanation:

Lets substitute y with 2x. We get: 1.85x+7.4x=12.95.

Simplifying by combining x: 9.25x=12.95

Then you just divide 12.95 by 9.25: x=1.4

Now for y. We know why is 2x so we just have to multiply x by 2: y=2x, y=2.8.

Find the volume of the solid figure shown below. The area of the base is 40 square inches and the height of the figure is 7 inch

Marrrta [24]

Answer:

$\displaystyle V _{ \text{cuboid}} =280 {in}^{3}$

Step-by-step explanation:

we are given the base area and the height of a solid figure

since the base area is not perfect square

we assure the solid figure to be a cuboid

remember that,

$\displaystyle V _{ \text{cuboid}} = l\times w \times h$

we are given l×w is 40 and h is 7

so substitute

$\displaystyle V _{ \text{cuboid}} =40 \times 7$

simplify multiplication:

$\displaystyle V _{ \text{cuboid}} =280$

hence,

the volume of the figure is 280 in³
