There are 258 students watching a lay in the auditorium there are 9 row with 20 in each and 6 rows with 7 students in each. how many student are sitting in each of the 3 remaining rows has an equal number of students

90 students are setting in each of the 3 remaining rows. 30 students in each row.

Step-by-step explanation:

20-6=14

14x9=126

6x7=42

126+42=168

258-168=90

90/3=30

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.
