Answer:
The given system has NO SOLUTION.
Step-by-step explanation:
Here, the given system of equation is:
6 x - 2 y = 5 .......... (1)
3 x - y = 10 .... (2)
Multiply equation 2 with (-2), we get:
3 x - y = 10 ( x -2)
⇒ - 6 x + 2 y = - 20
Now, ADD this to equation (1) , we get:
6 x - 2 y - 6 x + 2 y = 5 - 20
or, 0 = - 15
WHICH IS NOT POSSIBLE as 0 ≠ -15
Hence, the given system has NO SOLUTION.

Answer:
- c = 2
- segments 10, 8, 6 (top down)
Step-by-step explanation:
The sum of top and bottom bases is twice the midsegment.
(c² +6) +(c² +2) = 2(4c)
2c² -8c +8 = 0 . . . . . . . . . subtract 8c
2(c -2)² = 0 . . . . . . . . factor
c = 2 . . . . . . the value that makes the binomial be zero
The value of c is 2; the segment lengths (top-down) are 10, 8, 6.
Answer:
hours per day
Step-by-step explanation:
Given,
Distance = 192 miles
Rate = 9.6 miles per hour
Lets find her total time of riding by using Distance Formula ( D = RT ).
D = RT
192 = 9.6T
T = 192/9.6
T = 20 hours
Total time she needs to meet goals is 20 hours.
There are 7 days in a week and she plans to ride same hours each day, so that will be:
20/7 hours per day
The answer is a. 2 of the sides are the same and one angle is the same
Answer:
<h2>cos 60 = sin30 = 1/2 </h2>
