Answer:
Part 1)
Part 2)
Part 3)
Part 4)
Step-by-step explanation:
Part 1) HI = 3.9 and HJ = 6.2. Find IJ
we have that
I is between H and J
substitute the given values and solve for IJ
subtract 3.9 both sides
Rewrite
Part 2) JI = 25 and HI = 13. Find HJ
we have that
H is between I and J
remember that
IH=HI and IJ=JI
substitute the given values and solve for HJ
subtract 13 both sides
Rewrite
Part 3) H is the midpoint of IJ and IH = 0.75. Find HJ
we have that
H is between I and J and H is the midpoint of IJ
so
----> because H is the midpoint
we have
therefore
Part 4) H is the midpoint of IJ and IJ = 9.4. Find IH
we have that
H is between I and J and H is the midpoint of IJ
so
-----> equation A
----> equation B
substitute equation B in equation A
substitute the given value and solve for IH
Divide by 2 both sides
It took 32 minutes for Ella to go to school on Friday.
Step-by-step explanation:
Time for first four days in minutes,
30,28,34,31
Let x be the time on Friday
Average = 31 min
As we know
Multiplying both sides by 5;
It took 32 minutes for Ella to go to school on Friday.

Answer:
(x -1)(x -5)
Step-by-step explanation:
We recognize that 6 is the sum of the factors of 1·5, so we can write the factorization as ...
x^2 -6x +5 = (x -1)(x -5)
_____
The product of factors will be ...
(x +a)(x +b) = x^2 +(a+b)x +ab
So, the binomial constants "a" and "b" are factors of the trinomial constant that have a sum equal to the coefficient of the linear term. Here, those are factors of +5 that have a sum of -6. The factors of interest are -1 and -5: 5 = (-1)(-5); -6 = (-1) +(-5).
Five plus four x is equal to 2x-9
We can use the system of equation, where x = Mary and y = Jolene:
3x - 6 = y
x + y = 54
Hence,
x + (3x - 6) = 54
4x - 6 = 54
4x = 60
x = 15
And,
15 + y = 54
y = 39
