Answer:
1. gcd(77,30)=1

Since 1 is the last non zero remainder appearing in these equations then, 1 is the gcd of 77 and 30.
2. u=-11, v=18
Using the Euclidean Algorithm we have that

Now, we express the remainder as linear combinations of 49 and 30.

Then 
3. x=18
If
then
for some
.
Then, if k=7,

Answer:
54
Step-by-step explanation:
Just subtract the 12 years from the 66 years then you will get Thomas's age.
Answer:
D.
Step-by-step explanation:
Momentum(p) is Mass(m) times Velocity(v) or p = mv
The results of the calculations are attached. 0.4 kg at 2 m/s has the most momentum: 0.8 kg*m/s
75 percent of 225 is 168.75
Answer: x = 18
explanation: the two angles are congruent bc so you can set the equation up as 9x - 40 = 5x + 32 and then solve for x
hope this helps :)
