1 answer:
AveGali [126]2 years ago
4 0

Answer:

4 5/6 = n

Step-by-step explanation:

5 1/2 = n+ 2/3

Subtract 2/3 from each side

5 1/2 - 2/3 = n+ 2/3 -2/3

5 1/2 - 2/3 = n

Get a common denominator of 6

5 1/2 * 3/3 = 5 3/6

2/3 = 2/3 * 2/2 = 4/6

5 3/6 - 4/6 = n

We need to borrow 1 from the 5 in the form of 6/6

5 3/6 = 4 6/6+ 3/6 = 4 9/6

4 9/6 - 4/6 =n

4 5/6 = n

What is the value of k?
seraphim [82]

Answer:

k=2

Step-by-step explanation:

We have got a right triangle LNO with sides = m,4 and 8

By Pythagorean theorem

m^2=4^2 +8^2

Or m^2 = 80  ... i

IN triangle NOM, 4^2 +k^2 = l^2

i.e. 16+k^2 = l^2... i

In triangle LNM, m^2+l^2 = (8+k)^2

Substitute for m^2 as 80,

i.e. 80+l^2 = 64+k^2 +16k  ... iii

From i, l^2 = 16+k^2

Substitute in iii

80+16+k^2 = 64+k^2 +16k

16k = 32 or k =2
