Answer:

Step-by-step explanation:

$\frac{28}{z}-\frac{z}{4}+1\frac{1}{8}=\frac{28}{4}-\frac{4}{4}+\frac{9}{8}\\\\=7-1+\frac{9}{8}\\\\=6+\frac{9}{8}\\\\=\frac{6*8}{1*8}+\frac{9}{8}\\\\=\frac{48}{8}+\frac{9}{8}\\\\=\frac{57}{8}\\\\=7\frac{1}{8}$

The sum of two numbers is 50 and the difference is 4

juin [17]

Step-by-step explanation:

let the 2 numbers be x and x + 4 as their deference is 4.

their sum = 50

now,

→ x + x + 4 = 50

→ 2x + 4 = 50

→ 2x = 50 - 4 = 46

→ x = 46/2 = 23

therefore two numbers are,

x = 23

x + 4 = 23 + 4 = 27

hope this answer helps you dear...take care and may u have a great day ahead!
