Answer:
19 km/h
Step-by-step explanation:
average speed = total distance / total time
in this case it will be 57/3 = 19 km/h
Isolate the x. Note the equal sign. What you do to one side, you do to the other.
First, add 9 to both sides
3/4x - 9 (+9) = 27 (+9)
3/4x = 36
Next, multiply 4/3 to both sides
(4/3)(3/4)x = 36(4/3)
x = 36(4/3)
Simplify.
x = 12(4)
x = 48
48 is your answer for x.
hope this helps
Answer:
(4x3)+(5x3)=12+15=27
Step-by-step explanation:
You can multiple both by any number as long as it adds to nine. 4 plus 5=9.
You can also do 3+6=9, or 8+1=9
Answer:
(3,2)
Step-by-step explanation:
The solution that satisfies both equations is where the two lines intersects.
The two graphs intersect at x=3 and y =2
