Answer:
C. In a meeting room for a business event, there are 4 fewer chairs laid out in each row than the number of rows. The total number of chairs in the room is 60.
Step-by-step explanation:
To find the total number of chars, we multiply the number of rows by the number of chairs in each row.
Let the number of rows be x. There are 4 fewer chairs in each row than the number of rows; this gives us (x-4). Together, this gives us
x(x-4).
We know there are 60 chairs; this gives us
x(x-4) = 60
Using the distributive property,
x(x)-4(x) = 60
x²-4x = 60
Answer:
2 x <u>2</u> + 9 > 11
2 x 2 = 4
4 + 9 = 13
13 > 11
Therefore, x = 2.

Step-by-step explanation:
straight line = 180 degree
example
1) 2w - 24 + 2w - 40 = 180
4w = 180 + 24 + 40
4w = 244
w = 244/4
.......
2) 13n - 11 +(-9 + 12n)
13n - 11 -9 + 12n = 180
25n -20 = 180
25n = 180 + 20
25n = 200
n = 200/25
.........
Let x=3.77777777...
10x=37.777777777...
9x=10x-x=34
9x=34 so x=34/9=3 7/9
