Solve for x: 12-2x=-2(y-x)

1 answer:

3 0

12 - 2x = -2(y - x)

12 - 2x = -2y - (-2x)

12 - 2x = -2y + 2x

12 - 2x - 2x = -2y + 2x - 2x

12 - 4x = -2y

12 - 12 - 4x = -2y - 12

-4x = -2y - 12

-4x/4 = -2y/4 - 12/4

-x = -0.5y - 3

-x/-1 = -0.5y/-1 - 3/-1

x = 0.5y + 3

or

x = 3 + 0.5y

X = 3y - 6 2x - 4y = 8 Solve the system of equations using substitution.

Brut [27]

Hello

x = 3y - 6
2x - 4y = 8
We need to start by solving 3y - 6 for x
Substitute 3y -6 for x in 2x
2x - 4y = 8
2(3y - 6) - 4y = 8
2y - 12 = 8
2y = 8 + 12
2y = 20
Divide both sides by 2
2y/2 = 20/2
y = 10

Now, substitute 10 for y in x= 3y
x = 3y - 6
x = 3(10) - 6
x = 30 - 6
x= 24

Answer : x = 24 and y=10

I hope this help!

What is If a rectangular prism has a length, width, and height of centimeter, centimeter, and centimeter, respectively, then the

USPshnik [31]

Answer:

The volume is 105/512 cubic inches

Step-by-step explanation:

Given [Missing from the question]

$L = \frac{3}{8} cm$ -- Length

$W=\frac{5}{8}cm$ -- Width

$H = \frac{7}{8}cm$ -- Height

Required

Determine the volume.

The volume (V) is calculated as thus:

$V = L *W *H$

$V = \frac{3}{8} cm* \frac{5}{8}cm * \frac{7}{8}cm$

$V = \frac{3}{8} * \frac{5}{8} * \frac{7}{8}cm^3$

$V = \frac{3*5*7}{8*8*8}cm^3$

$V = \frac{105}{512}cm^3$

Which 2 equations would you use to solve this system?

slega [8]

Answer:

x-y=4

and

x+y=32 is your equation

difference of two number =x-y is equal to 4

sum of two number=x+y is equal to 32

x-y=4.......(1)

x+y=32.......(2)

adding equation 1 and 2

x-y +x+y=4+32

2x=36

x=36/2=16answer

substituting value of y in equation 1

16-y=4

16-4=y

y=12 answer

Kitty [74]

1.) 75 x .62 = 46.5 I multiplied by .62 because the kph to mph ratio is 1:.62
2.) 20 x 1.6 = 32 I multiplied by 1.6 because that's how many km are in a mile.
