Well, if he walks 3 miles in 1hr, then divide the hour by 3 to get one mile in 20 min, then multiply it by 7 to get 2 hours and 20 min to walk 7 miles. Hope his helped!
Answer:
33.6
Step-by-step explanation:
As we can see in the graph, the points:
- P is located at (-2, 8)
- Q is located at ( 6, 8)
- R( is located at (6, 2)
- S is located at (-5, 0)
To find a distance between two points or the length of the segment, we use the following formula:
Because the two points P and Q are located at the same libe y = 8
=> the lenght of PQ =
Because the two points R and Q are located at the same libe x = 6
=> the length of RQ =
The lenght of RS is: =
The lenght of SP is: = 8.5
=> the perimeter of quadrilateral PQRS = PQ+RQ+RS+SP
= 8+6+11.1+8.5
= 33.6
8x - 3 =5(2x + 1)
30) 8x - 3 = 10x + 5 ..............G. Distributive property
31) -2x - 3 = 5 ........................A. Subtraction property
32) -2x = 8..............................B. Addition property
33) x = -4................................F. Division property
34)
3x^3 -5x^2 - 13x + 3 by x - 3
answer
D. 3x^2 + 4x - 1
35)
(0, 1) and (1, 0)
answer is
y = |x - 1|
Answer:
- 15 is your answer.
I hope it will help you a lot.
