Answer:
d
Step-by-step explanation:
always d
Answer:
y = 30
x = 60
Step-by-step explanation:
4y and 2y are consecutive angles, which means they are equal to 180° when added together
that is the same with x and (5x - 180)
to solve, you set the equations to 180
solving:
4y + 2y = 180
6y = 180
y = 30
x + 5x - 180 = 180
6x = 360
x = 60
You could do 97.52/10. The slash means divided by.
Answer:
None, the answer should be a=1/2
Step-by-step explanation:
Lets solve the system by ourselves.
Lets sum 'a' variable to both sides of equality sign.
We have
4a+1=3
Now lets subtract 1 to both sides of equality sign
4a=2
we obtain a=1/2.
The speed is the ratio between the distance and the time:

Data:
d=6343miles
t=9h

Then, the plane traveled at a speed of 704.77 miles per hour.
