The answer is B. 45m/s north
Answer:
10.95
Step-by-step explanation:
<span>t+u = 10
10u+t= 10t+u-54
Rearrange:
t+u=10
9t-9u=54
Simplify:
1st; t+u=10
2nd: t-u=6
Add 1st and 2nd and solve for t,as follows:
2t = 16
t = 8
Substitute in t+u=10 to solve for u:
8+u=10
u = 2
Original Number = 82</span>
Answer:
-21 =x
Step-by-step explanation:
3x – 10 = 5x + 32
Subtract 3x from each side
3x-3x – 10 = 5x-3x + 32
-10 =2x +32
Subtract 32 from each side
-10 -32 = 2x+32-32
-42 = 2x
Divide each side by 2
-42/2 = 2x/2
-21 =x
The area of the triangle is 60.
12 x 10 = 120
120/2 = 60
