\frac{2.5}{3.5}=\frac{2.5 \times 2}{3.5 \times 2}=\frac{5}{7}

They are the same fraction, so they are proportional.

Rearrange the equation so x is the independent variable. y+6=5(x-4)
soldier1979 [14.2K]

Answer:

x = (y + 26)/5

Step-by-step explanation:

Order of Operations: BPEMDAS

Step 1: Write out equation

y + 6 = 5(x - 4)

Step 2: Distribute

y + 6 = 5x - 20

Step 3: Isolate <em>x</em>

y + 26 = 5x

Step 4: Isolate variable <em>x</em>

(y + 26)/5 = x

Step 5: Rewrite

x = (y + 26)/5

Answer:

288 cu in

Step-by-step explanation:

The Two end pieces

l = 6

w = 4

h = 4

V = l*w*h

V = 6*4*4

V = 96

But there are two end pieces. So the volume for both is 2 * 96 = 192

Middle Piece

L = 8

w = 4

h = 3

Volume = l * w * h

Volume = 8 * 4 * 3

Volume = 96

Total Volume

Total Volume = 96 + 192

Total Volume = 288 Cu in
