Answer:
im assuming that is a parallelogram and that youre solving for x so
2x - 5 = 17
2x = 22
<u>x = 11</u>
Answer:
(8.5, - 2 )
Step-by-step explanation:
Given the 2 equations
6x + 4y = 43 → (1)
2x - 3y = 23 → (2)
Multiplying (2) by - 3 and adding to (1) will eliminate the term in x
- 6x + 9y = - 69 → (3)
Add (1) and (3) term by term to eliminate x, that is
13y = - 26 ( divide both sides by 13 )
y = - 2
Substitute y = - 2 in either of the 2 equations and solve for x
Substituting into (1)
6x + 4(- 2) = 43
6x - 8 = 43 ( add 8 to both sides )
6x = 51 ( divide both sides by 6 )
x = 8.5
Solution is (8.5, - 2 )
Answer:
66.6
Step-by-step explanation:
1200/1800x100 = 66.6
its just 0...
Thats all its -1+1 so it would equal zero
Think about it like this
-1+1 = 1+(-1)
and when you add a negative what are you doing? Subtracting!
so 1-1 equals...?
0
S = V*t
3.5 hrs * 4.2 mph = 14.7 mi
t = S/V
14.7 mi/ 2.8 mph = 5.25 hrs
