Simplified to nearest whole number = 79
hope this helps:)
We know the perimeter is the total sum of all sides of the shape, we can use this to form an equation: the perimeter=1st side + 2nd side + 3rd side + 4th side 39a-7=9a+(5a+1)+(17a-6)+4th side.
Collect like terms to get 39a-7=31a-5+4th side
If we move everything but the 4th side over to the left we can solve
C. 8a-2=4th side is the correct answer
1 1/3 hours. 3/4 plus 7/12 equals 1 1/3. Hope this helps
Answer: Alberto traveled 792 miles as total distance.
Step-by-step explanation:
Since we have given that
Distance rode by the train = 198 miles
Number of times round tip in last month = 4 times
We need to find the total distance that Alberto traveled.
So, Total distance that Alberto traveled is given by

Hence, Alberto traveled 792 miles as total distance.
First do 75-5 then multypliy 2.6
