Rearrange the equation so b is the independent variable. 4a+b=−52

Anuta_ua [19.1K]

Answer:

$a= \frac{-52-b}{4}$

Step-by-step explanation:

Rearrange the equation so b is the independent variable.

To get 'b' as a independent variable , we need to get 'a' alone

WE need to solve for 'a' so that 'a' depends on variable b and 'b' becomes independent variable

4a+b=−52

To get 'a' alone , subtract 'b' from both sides

4a = -52-b

Divide by 4 on both sides

$a= \frac{-52-b}{4}$

A grill at a restaurant will be used to cook racks of ribs that are 1 lb. each and briskets that are 5 lb. each. No more than 13

ZanzabumX [31]

<h2>Answer:</h2><h2>The equation representing them ,1x + 5y ≤ 130</h2>

Step-by-step explanation:

A grill at a restaurant will be used to cook racks of ribs that are 1 lb. each and briskets that are 5 lb.

Let the number of rack of ribs be x and grill be y

No more than 130 lb. of ribs and brisket will be cooked on the grill.

The maximum briskets must be less than or equal to 130

Such that the equation representing them be,

1x + 5y ≤ 130

Possible combinations of y be 1,2,3 ....

when y =1, x + 5 ≤ 130, x = 125

when y = 2, x + 10 ≤ 130, x = 120

when y = 3, x + 15 ≤ 130, x = 115 and so on..
