182 m^ (Third answer) because it is not the volume

2 rectangles measuring 17x2 2(17x2)= 2x34 = 68 m^

2rectangles measuring 17x3 2(17x3)=2x51+102 m^

2rectangles measuring 3x2 2(3x2)=2x6=12 m^

TOTAL---------------------------------------------------------182 m^

2. Simplify. 10(x + 2)(x – 3) 5(2 – 3)(x + 6)

nignag [31]

Answer:

If the first one, 10x² - 10x - 60. For the second one, -5x - 30

Step-by-step explanation:

10(x + 2)(x – 3)

10(x²- x -6)

10x² - 10x - 60

5(2 – 3)(x + 6)

5(2x + 12 - 3x -18)

5(-x -6)

-5x - 30

Hello, I'm trying to solve 6x + y = 4, x - 4y = 19. I have found the y but I cant seem to find the x. Plz help and we cant use d

Answer:

$x=\frac{7}{5}$

$y=-\frac{22}{5}$

Step-by-step explanation:

Given:

The given expressions are.

$6x+y=4$

$x-4y=19$

We need to find x and y values.

Solution:

Equation 1⇒ $6x+y=4$

Equation 2⇒ $x-4y=19$

First solve the equation 1 for y.

$6x+y=4$

$y = 4-6x$ --------(3)

Substitute $y = 4-6x$ in equation 2.

$x-4(4-6x)=19$

Simplify.

$x-(4\times 4 - 4\times 6x)=19$

$x-(16-24x)=19$

$x-16+24x=19$

Add 16 both side of the equation.

$25x-16+16=19+16$

$25x=35$

$x=\frac{35}{25}$

Divide Numerator and denominator by 5.

$x=\frac{7}{5}$

Substitute x value in equation 3 and simplify.

$y=4-6(\frac{7}{5})$

$y=4-\frac{6\times 7}{5}$

$y=4-\frac{42}{5}$

$y=\frac{5\times 4-42}{5}$

$y=\frac{20-42}{5}$

$y=-\frac{22}{5}$ .

Therefore, the value of $x=\frac{7}{5}$ and $y=-\frac{22}{5}$ .

3y-8/12 =y/5 What is the solution to the proportion?

Gelneren [198K]

Answer:

y = 40/3

Step-by-step explanation:

For greater clarity please write 3y-8/12 =y/5 as:

3y-8 y

-------- = ------

12 5

Cross-multiplying, we get:

15y - 40 = 12y

Combining the y terms yields 3y = 40, so that y = 40/3
