X=number looked for
we have this equation:
-52(x-14)=x+3
we solve this equation:
-52x+728=x+3
-52x-x=3-728
-53x=-725
x=-725/-53=725/53 ≈13,68
Solution: 725/53
To check:
the difference between 725/53 and 14=725/53 - 14=(725-742)/53=-17/53
-52 times the diference is= -52(-17/53)=884/53
The number plus 3=725/53 + 3=(725+159)/53=884/53
1. 40/60 + 15/60 + 24/60 + 10/60 = 1.48
2.30/60 + 20/60 + 15/60 + 12/60 + 10/60 = 1.45
Answer:
59.9 mph or rounded to the nearest tenth (60 mph)
Step-by-step explanation:
Speed=Distance÷time
Distance-1798
Time-30
Speed-?
1798÷30=59.9mph or 60mph
