Step-by-step explanation:
171 km/h
travel distance = 855 km
855 / 171 = 5 hours
it took him 5 hours to fly the 855 km (theoretically to the hospital).
normally, with a plane, you can't land on or at a hospital. you would need a helicopter to be able to do that.
so, he could only fly to a nearby airport, and then travel from there to the hospital. but we have no information about that.
Answer:
y= 4 , x= -1
Step-by-step explanation:
3x-9y= -39
-3x-7y= -25
-16y= -64
y= -64/-16
y= 4
substitute y into any equation
3x -9(4) = -39
3x-36= -39
3x= -39+36
3x= -3
x= -3/3
x= -1
<u>Solution</u>:
3y = -9x - 22
y = -3x - 22/3
The graph parallel to this graph (9x + 3y = -22) should have a gradient of -3
In the choices above i.e A,B,C & D there is not a single equation with a gradient equal to -3.
Answer:
x = 14
Step-by-step explanation:
These angles are vertical each other, another way of saying they are opposite each other in an X. Since these angles are vertical, they are equal!
60 = 5x - 10 | Given, from here on is basic algebra
70 = 5x | Add 10 to both sides
14 = x | Divide both sides by 5
