Answer:
74.7 km/h
Step-by-step explanation:
The computation of the average speed is shown below:
As we know that
Speed = Distance ÷ Time
where
Distance = 66 km
And, the time is from 14.54 to 15.47 is 53 minutes
So, the speed is
= 66 km ÷ 53 minutes
= 74.71698 kilometers per hour
= 74.7 km/h
Answer:
53$
Step-by-step explanation:
They tell you the equation of how much the coin is worth after x amount of years
Step 1: Substitute x=19 into the equation y=2x+15
y = 2(19) + 15
Step 2: Solve for y
y = 2(19) + 15
y = 38 + 15
y = 53
Therefore the coin is worth 53 dollars after 19 years
Answer:
2(4a + 1)
Step-by-step explanation:
combined like terms: 4a + 6a - 3a and 5 + 3 - 6
when you combined these 2 terms, it's 8
a
+
2
8
a
+
2 = 2(4a + 1)
your choices:
2(8a + 1) = 16a + 2 ( not what we are looking for)
2(8a + 2) = 16a + 4 ( not what we are looking for)
2(4a + 1) = 8a + 2 ( the answer that we are looking for)
8a + 4 ( we are looking for 8a+ 2 not 8a + 4)
Therefore, 2(4a + 1) is the correct answer
