<span>Call the first odd number x.
That means the next odd number would be x+2.
For example, if the first odd number is 9 then the next one would be 11, which is why it is plus 2. Okay?
So then, x+x+2=128
2x+2=128
2x=126
x=63
x+2=65
Thus, the two consecutive odd numbers are 63 and 65.
Hope I helped :)</span>
Answer:
Nina's rate in miles per hour is 2.7 miles/hour
Nina bikes faster
Step-by-step explanation:
we know that
1 hour=3,600 seconds
1 mile=5,280 feet
<em>Convert feet to miles</em>
63,360 feet=63,360/5,280=12 miles
Convert seconds to hours
3,400 sec=3,400/3,600=0.94 hours
Find Nina's rate in miles per hour
12/0.94=12.7 miles/hour
Sophia's rate in miles per hour is 10 miles/hour
Compare the rates
12.7 miles/hour > 10 miles/hour
therefore
Nina bikes faster
Answer:
y = 18x + 21
Step-by-step explanation:
Let x be the amount of hours of the renting and y the final cost
y = 18x + 21
In fact the final cost depends from the hours of the renting
Move the decimal to the right 11 times. 2,456,00,000,000
You are going to use the equation y2-y1/x2-x1, and you will get negtive 4
