Answer:
Can only be simplified through calculator using decimal equivalents.
Step-by-step explanation:
The perimeter of a rectangle is the formula P=2l+2w. Here 
and 
. So the perimeter is:
Answer:
five trucks per hour
Step-by-step explanation:
20 because when you do it that way when it is behind the decimal the numbers are always the opposite thousand hundred tens ones . tens hundreds thousands
Answer:
A: -6.5
Step-by-step explanation:
Take two points that we already know are on the line and find the slope
I used:
(4, -10) and (7, -30)
X1 (first x coordinate): 4
Y1 (first y coordinate): -10
X2 (second x coordinate): 7
Y2 (second y coordinate): 30
These appear to be exactly on the graph at a certain point along the line. We can't choose a coordinate pair that isn't on the line at an exact point.
Use (Y2-Y1)/(X2-X1)
(-30-(-10))/(7-4) = (-30 + 10)/3 = -20/3 = approximately -6.67.
The closest answer to that is A.
B and D are the same as your expression because adding a negative number is the same as taking away. whereas in A and C, taking away a negative is the same as adding, which you don't want
