Simplify this expression 11(3p+5x)4x-x

Order of operations rules (PEMDAS) require that we perform multiplication first in this expression, 11(3p+5x)4x-x. Working from left to right, we obtain first:

(33p + 55x)(4x) - x. Here we have another, similar, multiplication to do, and the result is:

132px + 220x^2 - x

This in itself is a satisfactory answer. You could, if you wished to do so, factor out x to the first power:

x(132p + 220x - 1).

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.
