Gerald purchased 55 shaving stones to use in his garden the graph shows points representing the number of stones left to place at several different times will do all this working select from the drop-down menus to complete the equation in standard form that represents the relationship between the number of paving stones left to play y and the time x gerald has spent working. +y=

Answer-

Solution-

In the graph, on the abscissa time in hours is represented and on the ordinate the number of stones left is represented.

From the graph we have three points, they are (0, 55), (3, 40), (7, 20)

Taking any two points and applying two point formula of straight line, we can get the equation or relation between the two variables.

Taking (0, 55), (3, 40)

Therefore, 5x+y=55 is the correct relationship that represents the number of paving stones left to play y and the time x Gerald has spent working.

i used to know how to do this in 7th but i forget easily

step-by-step explanation:

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
