To solve problem 1 what you need to do is figure out how many miles the girls have walked so far and then subtract that from the total distance they must complete.
3/4-(3/10+1/4)
Step 1:Change the denominators so that way they are all the same
3/4=15/20
3/10=6/20 15/20-(6/20+5/20)
1/4=5/20
Step 2: Begin solving the problem
6/20+5/20=11/20
15/20-11/20=4/20
Step 3: Simplify your answer
4/20=1/5
Step 4 (is optional): Write your answer in a complete statement
The three girls walk 1/5mile together to school
Answer: A
I hope this is correct and if not I apologize for giving false information.
Given:
A car traveled 150 km in 3 hour.
To find:
The unit rate.
Solution:
We have,
Distance = 150 km
Time = 3 hours.
In this case speed is the unit rate.
Substituting the given values, we get
Therefore, the unit rate is 50 km/h.
Subtract 25 from each side of that equation, and it says that x-squared = negative 25. 'X' can't be any real number. If you know how to work with imaginary numbers, you'll know that the two solutions are x=5i and x=-5i ... the ' i ' is the symbol meaning the square root of -1 .
a1=5
a2=5+2=7
a3=7+2=9
a4=9+2=11
a5=11+2=13
Therefore the sequence is 5,7,9,11,13
Answer:
hope you have a good day to,☺
