Answer:
343
Step-by-step explanation:
Because the 5 rounds 9 to a 10, making the 7 an 8, hence:
342.8

Answer:
(-1,9)
Step-by-step explanation:
y = -3x + 6
y = 9
-3x + 6 = 9
-3x = 3
x = -1
y is already given as 9, but you can solve for y by plugging the x value into y = -3x + 6,
-3(-1) + 6 = 9
(-1,9)
Put in a equality
20 > (70/x)
then you solve
20x > 70
x>70/20
x> 3.5 you can not put part of a chair in a row so you round up
****You can put 4 or more chairs in a row****
