Answer:
Step-by-step explanation:
Perimeter is found by adding together all the lengths of the sides. For us, that is x + (2x + 5) + (6x - 17) + (3x + 2). Now we will just combine like terms. We can also drop the parenthesis because they do nothing for us and mean nothing to the problem.
x + 2x + 5 + 6x - 17 + 3x + 2 becomes
12x - 10
Answer:
The midpoint is ( 1.5, -1.5)
Step-by-step explanation:
To find the x coordinate of the midpoint, add the x coordinates of the endpoint and divide by 2
( -2+5)/2 = 3/2 =1.5
To find the y coordinate of the midpoint, add the y coordinates of the endpoint and divide by 2
( 3-6)/2 = -3/2 =-1.5
The midpoint is ( 1.5, -1.5)
Less.
There are 1000m in 1km.
measure of angle CED is 80
David will finish first, because if you divide Brad's miles by 2 to his miles in a 1/4 of an hour are 5.95 miles. This means David went 6.2 miles in the same time that Brad went 5.95. Therefore, David will finish first.
