Hello,
y=2x+5
==========
(y-5)=2(x-0)
6 mph.
To find this, create a ratio.
2/20 = x/60
This will allow you to compare here time of twenty minutes to an hour in the same context.
Multiply 2 by 60 and divide by 20 to get the answer of 6 mph.
Thus, Sabrina's average speed in miles per hour is six miles per hour.
Hope this helps!
Answer:
-11/12 make sure you press the negative
Step-by-step explanation:
3x+8y=27
3x=27-8y
x=27-8y/3
4(27-8y/3) + 3y=13
36-32/3y +3y =13
36-23/3y=13
36-13=23/3y
y=3
x=1
Answer:
80 minutes
Step-by-step explanation:
1 hour=60 minutes
2 hours=120 minutes
-------------------------------
15/120=10/x
cross product
120*10=15*x
1200=15x
x=1200/15
x=80
