Answer:
hope this helps :)
Step-by-step explanation:
Since we know how far she can walk in 1/5 (one fifth) of an hour, if we multiply this distance by 5, we will find out how far she can walking in 5/5 (five fifths) of an hour, or to be clear: in one hour.
So, 5 x 1/4 miles = 5/4 or 1.25 miles per hour
Jazmeen can walk 1.25 miles in one hour.
Answer: the integers are 4,5and 6
Step-by-step explanation: lets say the integers are: x,x+1,x+2
consecutive integers are numbers that follow each other like:1,2,3 or 2,3,4 in that sequence.
since the sum of the integers has been given to be 15 we add our equation: x+x+1+x+2=15
- add the like termsx+x+x+1+2=15
- 3x+3=15
- 3x=15-3=12
- 3x=12
- divide on both sides by 3 to get
- x=4
- lets substitute our answer to our equation
- if x=4
- x+1=4+1=5
- x+2=4+2=6
- therefore the integers are:4,5 and6
Answer:
y = sqrt(29)/2 - 1/2 or y = -1/2 - sqrt(29)/2
Step-by-step explanation:
Solve for y:
y^2 + y - 7 = 0
Add 7 to both sides:
y^2 + y = 7
Add 1/4 to both sides:
y^2 + y + 1/4 = 29/4
Write the left hand side as a square:
(y + 1/2)^2 = 29/4
Take the square root of both sides:
y + 1/2 = sqrt(29)/2 or y + 1/2 = -sqrt(29)/2
Subtract 1/2 from both sides:
y = sqrt(29)/2 - 1/2 or y + 1/2 = -sqrt(29)/2
Subtract 1/2 from both sides:
Answer: y = sqrt(29)/2 - 1/2 or y = -1/2 - sqrt(29)/2
Answer:
13.3 miles
Step-by-step explanation:
So you're driving <----- for 3 miles
Then you start driving up for 13 miles
This makes a right triangle with sides of 3 and 13
using pathagoreas, a^2+b^2=c^2
3^2+13^2=c^2
9+169=c^2
178=c^2
Square root both sides
c= 13.3416640641
Rounding, it's 13.3 miles
Answer:
that's an equation
