4 hours and 25 minutes before 2:05am
Answers
4 hours and 25 minutes before 2:95 am would be 9:40pm
Answer:10:20 pm
Step-by-step explanation:
Time is seperated into 2 sets of 12 hours, am and pm; and 24 hours with each being 60 minutes. AM is morning and PM is afternoon.
The question is what time is 4 hours and 25 minutes before 2:05 in the afternoon. This means you subtract.
205 - 425= -220
Then, because it is negative, you change it from am to pm and subtract 220 from 1200=
1200-220=980
9:80 is has too high a number in the minutes section (the second part) so you see how many sets of 60 are in 80. There is one set of 60 meaning there is one hour added to the hour side (the left side):
9+1: 80-60
10:20
10:20 pm is the final answer.
Hope this helped;)

Multiply both sides of the equation by 2
2x - 6 = 40 then add 6 to both sides,
2x = 46 divide both sides by 2
x = 23
Final answer:
To find the number, we need to work backwards from the given quotient of 20. Double the number, subtract 6, and divide the result by 2 to get the number.
Explanation:
To find the number, we need to work backwards from the given quotient of 20. Let's call the number x.
Step 1: Double the number: 2x
Step 2: Subtract 6 from the result: 2x - 6
Step 3: Divide the answer by 2: (2x - 6) ÷ 2
Since the quotient is 20, we can set up an equation: (2x - 6) ÷ 2 = 20
Multiply both sides of the equation by 2: 2x - 6 = 40
Add 6 to both sides of the equation: 2x = 46
Divide both sides of the equation by 2: x = 23
Therefore, the number is 23.

1. replace f(x) or g(x) or f(n) with y
2. switch places of x and y
3. solve for y
4. replace y with f⁻¹(x) or g⁻¹(x) or f⁻¹(n)
1.
g(x)=3+(x-1)^3
replace
y=3+(x-1)^3
switch
x=3+(y-1)^3
solve
x=3+(y-1)^3
subtract 3
x-3=(y-1)^3
cube root both sides
add 1
switch y with g⁻¹(x)
g⁻¹(x)=
4. f(x)=x^3+2
replace with y
y=x^3+2
switch x and y
x=y^3+2
solve for y
x=y^3+2
subtract 2
x-2=y^3
cube roo both sides
replace with f⁻¹(x)
f⁻¹(x)=
5.
f(n)=5
replace
y=5
switch n and y
n=5
solve for y
n=5
divide both sides by 5
n/5=n=
square both sides
subtract 1/2 from both sides
multiply both sides by -1

Answer: for this you will simply have to use the straightedge to draw two parallel lines and then you draw a line that goes through them that is perpendicular. You then use the compass to measure the angles, they should be congruent and adjacent.
I hope it helps, Regards.
with compass point at A , draw a large arc cutting the line at C
then place compass at point c and draw a small arc through D
Then keeping the compass point at C, draw a similar small arc at E
Join A and E with straight edge

(8, 8) and (0, 8). If the equation is y = any number, the second coordinate will always be that number. :)
I took the test and got that one wrong, the true answer is 0,8 and 8,8. It was just backwards. Your answer was just needing to be flipped, first last and last first. to get 0,8 and 8,8.
