Solve for y Please help I need a tip

Gwar [14]

Answer:

y = 4

Step-by-step explanation:

Step 1: Write equation

9/4y - 12 = 1/4y - 4

Step 2: Solve for y

Subtract 1/4y on both sides: 8/4y - 12 = -4
Simplify: 2y - 12 = -4
Add 12 to both sides: 2y = 8
Divide both sides by 2: y = 4

Step 3: Check

Plug in x to verify it's a solution.

9/4(4) - 12 = 1/4(4) - 4

9 - 12 = 1 - 4

-3 = -3

The area of the trapezoid is 40 square units.

Whitepunk [10]

Answer:

5 units

Step-by-step explanation:

Image of the trapezoid is attached.

To find the height of the trapezoid (image attached), let's take the formula for area of a trapezoid.

The formula for area of a trapezoid is:

$A = (\frac{a + b}{2}) h$

Here, a and b represents the bases of the trapezoid.

a = 6

b = 10

h which represents height is unknown.

A = 40

Substitute figures:

$40 = (\frac{6 + 10}{2}) h$

$40 = (\frac{16}{2}) h$

$40 = 8 * h$

Solve for h:

$h = \frac{40}{8}$

$h = 5$

The height of the trapezoid is 5 units

3x+9 -------- how do I solve this? 4x+12

Reptile [31]

Put common terms in evidence and simplify:

$\boxed{\frac{3x+9}{4x+12}=\frac{3(x+3)}{4(x+3)}=\frac{3}{4}}$

The width of a rectangle is 6 in. less than its length. The perimeter is 68 in.

erma4kov [3.2K]

2L + 2(L-6) = 68

2L + 2L -12 = 68

4L = 80

L = 20

The length is 20 in. and the width is 14 in.
