It is given in the question that, a rocket travels 2.8x10^4 km h^-1.
It means in one hour, the rocket travels

And we have to find how much the rocket travels in 5 hours, and for that we have to do multiplication, that is

Answer:
1/3
Step-by-step explanation:
The equation given to you is in y=mx+b form.
m is the slope which in this case would be 2/9.
b is the y-intercept which in this case would be 1/3
First list all the factors of 12;
1, 2, 3, 4, 6, 12
now let's see which ones are multiples of 3;
3, 6, 12
so all we have left are numbers 1, 2 and 4.
hope that helps, God bless!
138° + w° = 180° (sum of angle on a straight line)
w° = 180° - 138°
w = 42
19° + x° + w° = 90°
sub. in w=42,
19° + x° + 42° = 90°
x° = 90° - 19° - 42°
x° = 29°
x = 29
If 19 is half (50%) of something, find that number you would just have to multiply 19 by 2.
This means that 19 is 50% of 38.
