Since it's perimeter, you're adding. the expression would be x + 2 4/5
9514 1404 393
Answer:
a) -1 5/14
b) -1/3
c) -1 : 10
Step-by-step explanation:
a) 1/7 - 0,5·3 = 1/7 -3/2 = (1·2 -3·7)/(7·2) = -19/14 = -1 5/14
__
b) (3/4 -0,25)·(-2/3) = (3/4 -1/4)·(-2/3) = (2/4)(-2/3) = (1/2)(-2/3) = (-1·2)/(2·3) = -1/3
__
c) (1 5/6 -1,2) : (-6 1/3) = (11/6 -6/5) : (-19/3) = (11·5 -6·6)/(6·5) : (-190/30)
= (19/30) : (-190/30) = -19 : 190 = -1 : 10
Answer:
Y= -1x - 4
Step-by-step explanation:
Here is the rule: 4 and below let it go (round down), 5 and above give it a shove (round up)
Look to the place after the thousandths in the number 3,176 (the 1)
Since it is below 5, you would round down to 3,000
