Answer:
20 miles
Step-by-step explanation:
Set up a proportion...
0.8 miles is to x miles as 6 mins is to 2.5 hours
*You need to convert 2.5 hours into minutes first, since the first part is in minutes. There are 60 minutes in an hour, so there are 60(2.5) = 150 minutes in 2.5 hours
0.8/x = 6/150
Now solve for x by cross multiplying...
0.8(150) = 6x
120 = 6x
20 = x
She can ride 20 miles in 2.5 hours
Answer:
Step-by-step explanation:
1)
?/10 =4/5
?/5×2 =4/5
4×2/5×2 =8/10 ... the number is : 8
2)
?/4 = 11/4....the number is : 11
By knowing that p and 2/3 are additive inverses, we will see that p = -2/3
So two numbers A and B are additive inverses if:
A + B = 0
Here the two numbers are p and 2/3, so we have:
2/3 + p = 0
Solving this for p gives:
p = -2/3
Then the value of p is just -2/3.
Now, I can't "drag and drop" the labels in the given image, so I will post a little graph of where each point should be:
