A + 4 = 2b
Nataliya [291]

Answer:

a=21

b=25/2

c=77/2

Step-by-step explanation:

from eq 1

a+4=2b => a=2b-4

substituting value of a in eq 2

c-5=a+b => c-5=2b-4+b => c =3b+1

now, substituting value of a and c in eq 3

a+b+c=72 => 2b-4+b+3b+1 =72 => 6b-3=72 => b= 75/6 => b=25/2

substituting value of b in :

c=3b+1 ( you will get c )

then substitute value of b in :

a=2b-4 ( to get a)

the length of a rectangle is 7 inches greater than three times its width write an expression to represent its area
icang [17]

Step-by-step explanation:

Let the length be L.

Let the breath be B.

So, we are given that

length of a rectangle is 7 inches greater than three times its width .

So, according to the Question,

L = 7+ 3B.

So, we know that:-

Area = Length× Breadth.

So, it will be

B × (7 + 3B) = Area.

So,

3B² + 7 is an expression to represent its area.
