Answer:
2.87miles
Step-by-step explanation:
Over the course of 6 days, Tonda ran 17.22 miles for 6 days, then;
6days = 17.22 miles
To know the distance covered in a day, we will writ;
1 day = x miles
Divide both equations
6/1 = 17.22/x
6x = 17.22
x = 17.22/6
x = 2.87miles
Hence Tonda ran 2.87miles per day
Answer:
-2w+-14
3d+3
-7y+-16
Step-by-step explanation:
Remove ()- <u>2w</u>+-9+<u>-4w</u>+-5
2w+-4w = -2w
-9+-5 = -14
-2w+-14
Remove ()- <u>6d</u>+5+-2+<u>-3d</u>
6d+-3d = 3d
5+-2 = 3
3d+3
Remove ()- 4+<u>-5y</u>+<u>-2y</u>+-16
-5y+-2y = -7y
4+-16 = -12
-7y+-12
Nolan correctly identified the square numbers before and after 18.
The square roots of them are 4 and 5.
Clearly, square root of 18 should lie between 4 and 5 only.
He, then carefully squared 4.1, 4.2, 4.3 etc. and identified that 4.3 squared is nearer to 18.
Since, Nolan is finding estimated square root, his steps are cool and he didn't make any error.
