Answer:

~28

Step-by-step explanation:

5 feet 3 inches is 5.25 feet.

We divide 7/5.25 which equals 1.3333333333333 (repeating)

That means we multiply 21 by 1.333333333333 which would round up to 28 feet. (the exact answer is 27.99999999999999999)

Solve the following proportion for 17/13=9/u

ValentinkaMS [17]

Answer:

Solution,

$\frac{17}{13} = \frac{9}{u}$

Sinplify the equation using cross multiplication

$17 \times u = 13 \times 9$

Calculate the product

$17u = 117$

Divide both sides of the equation by 17

$\frac{17u}{17} = \frac{117}{17}$

Calculate

$u = 6.88$

Hope this helps...

Good luck on your assignment..
