There are no real numbers that can do that job.
There's a pair of complex numbers that can do it.
They are
4.5 + i23.23
and
4.5 - i23.23 .
' i ' = the imaginary unit = √(-1)

Answer: Choice C
angle HDG = angle HFE
==========================================================
Explanation:
We have the statement given to us. Note that "H" is in the middle for both sequences of three letters. For DHG, start at H and move back one space to get to D. Move back another unit to wrap around to G. So the new sequence is HDG which forms the first angle.
Follow the same pattern but for FHE now. Start at H, move backward one spot to F, then move back again to wrap around to E. We have HFE
This shows angle HDG pairs up with angle HFE. The corresponding angles are congruent due to CPCTC
CPCTC = corresponding parts of congruent triangles are congruent
Notice how angles HDG and HFE are alternate interior angles, which lead to showing DG is parallel to EF.

t= 20/x seconds
b) d=25m
s= x+0.5 m/s
t= d/s = 25/x+0.5
c) total time = 6 seconds
therefore, 20/x + 25/x+0.5 = 6
make a common denominator of x(x+0.5):
(20(x+0.5) + 25x)/x(x+0.5) = 6
move the demoninator to the other side, and expand to form:
20x+10+25x = 6x(x+0.5)
45x+10= 6x^2 +3x
tidying it up (moving everything to one side)
6x^2 - 42x-10 = 0
divide everything by 2
3x^2-21x-5= 0 (as required)
d) use quadratic formula to solve
e) therefore, what does x equal?

Answer:
cost per ounce is 0.06 per ounce
Step-by-step explanation:
A 32 oz bottle of water costs $1.92.
we need to find the cost of one ounce.
To find the cost of 1 ounce , we need to divide the total cost by 32 oz
cost of 1 oz=
0.06 is the unit price
So, the cost per ounce is 0.06 per ounce
Answers
Answer:
Step-by-step explanation:
If Angela bought gift for her friend and each gift costs 10$. This means that the more the number of her friends, the more the money she will pay and vice versa. This is known as a direct relationship.
Let y represent the total cost and
x represent the number of gifts
According to direct variation]
y ∝ x
y = kx
k is the constant of proportionality
If each gift item cost $10, x gift will cost 10x. The constant of proportionality in this case will be 10. Substituting, the equation will become;
y = 10x
Hence the required relationship is y = 10x
