Answer:

x=1.33 repeating or 1 1/3

Step-by-step explanation:

You take 4 and distribute to everything in the parentheses.

You also do the same for the -4.

After you distribute, you should get: 4x+24=-8x+36+3x

Then you combine like terms (the two x's on the right side of the equation.

You should then get: 4x+24=-5x+36

Next, you subtract 24 from the positive 24, to cancel it out, and the 36 to get 12.

Then, add 5x to the negative 5x, to cancel it out, and to the 4x to get 9x.

Finally, you divide 12 by 9 to get 1.33 repeating or 1 1/3.

Max built a rectangular Prism and a rectangular Pyramid using beach sand. The prism and the pyramid have the same base area and

vova2212 [387]

Answer:

Three times

Step-by-step explanation:

Given

Figures: Rectangular Prism and Rectangular Pyramid

Let the dimension of the prism be:

$l = length$

$w = width$

$h = height$

Amount of sand used is the volume (V1) and it is calculated using;

$V_1 = l * w * h$

$V_1 = lw h$

Since the pyramid has the same base area and height as the prism, the its dimension would be:

$l = length$

$w = width$

$h = height$

Amount of sand used is the volume (V2) and it is calculated using;

$V_2 = \frac{1}{3}*(lwh)$

So, we have:

$V_1 = lw h$

$V_2 = \frac{1}{3}*(lwh)$

Substitute lwh for V1 in the second equation

$V_2 = \frac{1}{3}V_1$

Multiply both sides by 3

$3 * V_2 = \frac{1}{3}V_1 * 3$

$3 * V_2 = V_1$

Reorder

$V_1 = 3 * V_2$

$V_1 = 3 V_2$

<em>Hence, the amount of sand used in building the prism is three times the amount of sand used in building the pyramid</em>

Aliun [14]

Answer:

The Answer is: x / y = 8 / 3

Step-by-step explanation:

3(x - 2) - 4(2y - 1) + 2=0

3x - 6 - 8y + 4 + 2 = 0

3x - 8y = 0

3x = 8y

3x/y = 8

x / y = 8 / 3

If twelve pounds of nails cost $3.84 what is the unit cost A) 32c B) 28c C) 23c D) 18c

aalyn [17]

Answer:

Option A) 32c

Step-by-step explanation:

we know that

To find the unit cost, divide the total cost of twelve pounds by twelve pounds

$\frac{\$3.84}{12}=\$0.32$

Remember that

1$=100 cents

Convert dollars to cents

$\$0.32=0.32*100=32c$

therefore

The cost of one pound of nails cost 32 cents
