12 = -2x = 4y<br> Help please

ivolga24 [154]

Answer:

x=−2y+6

Step-by-step explanation:

Step 1: Add -12 to both sides.

−2x+12+−12=4y+−12

−2x=4y−12

Step 2: Divide both sides by -2.

−2x /−2 = 4y−12/−2

x=−2y+6

What is the missing length??

amid [387]

Answer

The missing length is 10

Step-by-step explanation:

Represent the missing length with x

The sides of the given shape are directly proportional.

Mathematically:

(15 + x) to (12 + 8) and x to 7

Represent as a ratio:

$(15 + x) : (12 + 8) = x : 8$

$15 + x : 20= x : 8$

Convert to fraction

$\frac{15 + x}{20} = \frac{x}{8}$

Cross Multiply:

$(15 + x)*8 = 20 * x$

$120 + 8x = 20x$

Collect Like Terms

$20x - 8x = 120$

$12x = 120$

Solve for x

$x = \frac{120}{10}$

$x = 10$

<em>The length of the missing side is 10</em>
