What is the justification for step 4 in the solution process? 9/2b + 11 – 5/6b = + 2
Step 1: 22/6b + 11 = 6 + 2
Step 2: 8/3b + 11 = 2
Step 3: 8/3b = 9
Step 4: b = -27/8

A. The subtraction property of equality

B. The multiplication property of equality

C. Combining like terms

D. The addition property of equality

Step-by-step explanation:

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
