Answer:
37.86 mph and 40.86 mph
Step-by-step explanation:
The speed for the first session is x, for the second session will be x+3
Average speed= (x+x+3)/2= x+1.5
Total distance covered will be 228+205=433 miles
Time= 11 hours
Time= Distance/ speed
Speed= distance/time
Average Speed= 433/11
x+1.5=433/11
x+1.5=39.36363636
x=39.36363636
-1.5= 37.86363636
Approximately, x= 37.86 mph
x+3=37.86+3= 40.86 mph
Answer:
y = -5 × 1 + 2
Step-by-step explanation:
- y = y, m = slope, x = x point given (1), b = y point given, unless a zero (2)
- Formula - y = mx + b
- Plug it in
- y = -5 × 1 + 2
Answer:
-3n-6
Step-by-step explanation:
multiply each term by 3
-3(n+2)
-3n-3*2
-3n-6
1.
3 x 4 = 12
3 + 4 = 12
The two integers a and b are : 3 and 4
2.
-4 x 1 = -4
-4 + 1 = -3
The two integers a and b are : -4 and 1
3.
-3 x -3 = 9
-3 + -3 = -6
The two integers a and b are : -3 and -3
There you go! I really hope this helped, if there's anything just let me know! :)
