A 155 inch board is cut into two pieces. One piece is four times the length of the other. Find the length of the shorter piece

31 in

Step-by-step explanation:

Let the length of the shorter piece be x inches.

Length of the longer piece= 4x inches

Total length= 155 in

4x +x= 155

5x= 155

x= 155 ÷5

x= 31

∴ The length of the shorter piece is 31 inches.

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.
