Suppose Z Varies directly with x and inversely with y, where x = 16, y = 4, when z = 32...............

Greeley [361]

A.)
Z = kx/y where k is a constant.
32 = 16k/4
k = 128/16
k = 8

z = 8x/y

b.)
Z = 8(21)/6
Z = 28

c.)
4 = 8x/48
x = 192/8
x = 24

UNO [17]

X² + 11x + 28 + x² + 13x + 40

combine like terms

x² + x² = 2x²
11x + 13x = 24x
28 + 40 = 68

2x² + 24x + 68 is your answer

if you want it simplified:

2(x² + 12x + 34)

Dan weighs 205 pounds but is only 5 feet 8 inches tall. Evan is 6 feet tall. How much would you expect Evan to weigh if they hav

Rina8888 [55]

Answer:

Around 217 pounds

Step-by-step explanation:

Let's convert the height into inches.

5 feet 8 = $5\cdot12 + 8 = 60 + 8 = 68$

6 feet $= 6\cdot12 = 72$ .

We can set up a proportion

$\frac{205}{68} = \frac{x}{72}$

We can use the cross products property to find x.

$205\cdot72=14760\\\\\\14760\div68\approx217$

Hope this helped!
