Brian should purchase Choice C of fabric

Solution:

Given that Brian wants to purchase a piece of fabric  that is between 49 and 53 inches long

So piece of fabric should be between: 49 and 53 inches

Let us convert feet to inches

Now convert to inches

We know that,

1 feet = 12 inches

But this choice is greater than given condition that piece of fabric should be between: 49 and 53 inches

So this is not correct

Now convert to inches

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5
