An electrician needs 3 1/4 rolls of electrical wire to wire each room in a house. how many rooms can he wire with 9 1/4 rolls of wire

Number of rooms can be wired by electrician is approximately 3

Solution:

Given that electrician needs rolls of electrical wire to wire each room in a house

To find: number of rooms can he wire with rolls of wire

From given information,

Rolls of wire needed for 1 room =

Total rolls of wire =

So number of rooms can be wired:

Thus number of rooms can be wired is or approximately 3 rooms

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

so then what are you asking?
