Solving for a gives us: a = P-c-b

Step-by-step explanation:

Solving an equation for a variable means that we have to isolate the variable in the equation

Given equation is:

P = a+c+b

For isolating a, subtracting c from both sides

P-c = a+c+b-c\\P-c = a+b

Subtracting b from both sides

P-c-b = a+b-b\\a = P-c-b

Hence,

Solving for a gives us: a = P-c-b

the perimeter of a rectangle is 55 inches. the ratio of the length to width is 7:4. use proportions to find the area of the rect
Leni [432]

Answer:

Step-by-step explanation:

let : x the length and y the width    .... ( x  > y and x ; y reals numbers )

the perimeter is : 2(x+y)

2(x+y) = 55...(1)

x/y = 7/4 ...(2)

by (2) : x = (7/4)y

subsct in (1) : 2( (7/4)y +y ) =55

(7/2)y +2y =55

multiply by 2

7y +4y = 110

11y = 110

y = 10

x = (7/4)(10)

x = 35/2
