Hi! Your answer is 13.
All you have to do is divide 52 by 4. When you do this, you will find how many laps they walked per hour.
(They walked 52 laps in 4 hours)
52 / 4 = 13
They walked 13 laps in one hour.
Hope this helped!
1) 52 + 33= 85
2) 26 + 42 = 68 or 26 - 42 = - 16
3) 72 - 2015 = =1943
4) 32 x 22 = 704
Answer:
Step-by-step explanation:
x = width
4x - 16 = length
x + x + (4x - 16) + (4x - 16) = 68
= x + x + 4x - 16 + 4x - 16 = 68
= 10x - 32 = 68
= 10x = 100
= x = 10
width = 10 feet
length = 24 feet
10 (2x + 3) = 15 x 9
20x + 30 = 135
20x = 135-30 = 105
x = 105 / 20 = 5.25
answer: x = 5.25
Answer:
4. x=120
5. x=65
9. x=150
10. x=45
Step-by-step explanation:
4. Half=180
There is already a 60, so you do 180-60=120. x=120.
5. This is a parallel line, so you determine the opposite angle of 115, which is 65. That just becomes the x. x=65
9. It is similar to #5, You look at the opposite side of 30 (15+15) which is 150. That just comes to the other side which is x=150.
10. A triangle has 180 degrees in total. 45 degrees is already given, and line j is 90 degrees which means a full line is 180. 180-90=90.
90+45=135
180-135=45
x=45
