Number 4 is C... 21
To complete the question, make the equation 5x + 15 + 3x - 3 = 180 because of supplementery angles.
Just solve for x to get 21.
Number 5 is C... 120
To complete this question, sub 21 in for X in the equation 3x - 3 to get 60. Subtract 60 from 180 to get 120.
Squirrel = 4/15 = 16/60
16 miles per hour
Fox = 21/30 = 42/60
42 miles per hour
42-16 = 26 miles per hour
Solution: Fox; 26 miles per hour faster
Answer:
Step-by-step explanation:
(3+9) + 13 could also be written as:
3 + 9 + 13 = 25, or
3 + (9 + 13) = 3 + 22 = 25, or
(3 + 9) + 13 = 12 + 13
We can group the addends in any way desired; this illustates the associative property.
So Angel hikes at 2.4 miles per hour. This says that in one hour he hikes 2.4 miles. In 1/3 of an hour then he would hike 1/3 of 2.4 miles, which is 2.4/3, or 0.8.
