Nina's steakhouse sold approximately 247 steaks that night.

Step-by-step explanation:

In order to calculate the number of steaks Nina's sold that night we can apply a rule of three, in a way that 34% is related to 84 steaks in the same proportion as 100% is related to "x" steaks. We have:

100% -> x steaks

34% -> 84 steaks

100/34 = x/84

34*x = 100*84

x = 100*84/34

x = 247.0588 steaks

Nina's steakhouse sold approximately 247 steaks that night.

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.

look at the picture i have filled out a table for it. hope this .
