Answer:

Step-by-step explanation:

so umm for me i have to convert it to a (i forgot the name for the opposite of mixed number lets just say a) a

soooo

2 1/8

17/8

now multiply

56 (17/8)

952/8

119

Answer:

119

Step-by-step explanation:

Convert into mixed numbers 2 1/8= 17/8

How to get that is

2 1/8= 2 times 8 + 1 divided by 8 = 17/8

Now you have 56 times 17/8

Convert element to fraction

56/1 times 17/8

Apply fraction rule

56 times 17 over 1 times 8

Multiple the denominators (1 times 8=8)

Now you have 56 times 17 over 8

Divide the numbers 56/8=7

Now, multiply

7 times 17= 119

Apply the Distributive Property

[tex]22k-39=11k+20k+24[/tex]

Combine like terms

[tex]22k-39=31k+24[/tex]

Rearrange variables to the left side of the equation

[tex]22k-31k=24+39[/tex]

Combine like terms

[tex]-9k=24+39[/tex]

Calculate the sum or difference

[tex]-9k=63[/tex]

Divide both sides of the equation by the coefficient of variable

[tex]k=-\frac{63}{9}[/tex]

Cross out the common factor
