*Number of amount in container* Divided by 5
Then get that original container amount then subtract the number you got from the previous equasion
This is my tactic and it always works for me
Rewrite each subtraction equation as an addition equation.
p - 20 = - 30
Answer:
p + 30 = 20
Step-by-step explanation:
we can add 30 to both sides to make this an addition equation:
p - 20 = -30 (now add 30 to both sides)
p - 20 + 30 = 0 (then, add 20 to both sides)
p + 30 = 20 (this would be the addition equation)

9514 1404 393
Answer:
a = 3b = 4c = 2d = 1Step-by-step explanation:
There are zeros at x=-1 and x=4, so numerator factors of (x +1) and (x -4).
There are vertical asymptotes at x=1 and x = -2, so denominator factors of (x-1) and (x+2).
There is a hole at x=-3, so another numerator factor of (x+3) to cancel the one in the denominator.
Comparing the above to the given expression for f(x) we see that ...
a = 3b = 4c = 2d = 1Find the area of the triangle.

I gotta say what's on my mind
Something about us doesn't seem right these days
Life keeps getting in the way
Whenever we try, somehow the plan
Is always rearranged
It's so hard to say
But I've gotta do what's best for me
You'll be okay
I've got to move on and be who I am
I just don't belong here
I hope you understand
We might find our place in this world someday
But at least for now
I gotta go my own way
Don't wanna leave it all behind
But I get my hopes up
And I watch them fall every time
Another color turns to grey
And it's just so hard to watch it all slowly fade away
I'm leaving today
'Cause I gotta do what's best for me
You'll be okay
I've got to move on and be who I am
I just don't belong here
I hope you understand
We might find our place in this world someday
But at least for now
I gotta go my own way
What about us?
What about everything we've been through?
What about trust?
You know I never wanted to hurt you
And what about me?
What am I supposed to do?
I gotta leave but I'll miss you
So I've got to move on and be who I am
(Why do you have to go?)
I just don't belong here
I hope you understand
(I'm trying to understand)
We might find our place in this world someday
But at least for now
(I want you to stay)
I gotta go my own way
I've got to move on and be who I am
(What about us?)
I just don't belong here
I hope you understand
(I'm trying to understand)
We might find our place in this world someday
But at least for now
I gotta go my own way
I gotta go my own way

Phone calls to New York are charged at the rate of £2.90 for a 5-minute call. John’s call costs £7.86. How long (in minutes) was his call?
Answer:
Step-by-step explanation:
5 min = 2.90
xmin = 7.86
with cross multiplication;
xmin = 7.86*5min/2.90
x = 13.55=14.0
therefore x = 14min
so he will make of 14min long

D. 137 [tex]m^{2}[/tex]
Step-by-step explanation:
First, get the area of the rectangle:
[tex]A_{Rectangle} =length *width[/tex]
[tex]A_{Rectangle}=(15)(11)=165[/tex]
Then, get the area of the triangle:
[tex]A_{Triangle} =\frac{height*base}{2}[/tex]
[tex]A_{Triangle}=\frac{8*7}{2} =28[/tex]
Now substract the area of the triangle from the rectangle:
165 - 28 = 137
∴ 137 [tex]m^{2}[/tex]

Solve for x when √(x ² - 4) = 1 :
√(x ² - 4) = 1
x ² - 4 = 1
x ² = 5
x = ±√5
We're looking at x ≤ 0, so we take the negative square root, x = -√5.
This means f (-√5) = 1, or in terms of the inverse of f, we have f ⁻¹(1) = -√5.
Now apply the inverse function theorem:
If f(a) = b, then (f ⁻¹)'(b) = 1 / f '(a).
We have
f(x) = √(x ² - 4) → f '(x) = x / √(x ² - 4)
So if a = -√5 and b = 1, we get
(f ⁻¹)'(1) = 1 / f ' (-√5)
(f ⁻¹)'(1) = √((-√5)² - 4) / (-√5) = -1/√5
The sign must be negative; see the attached plot, and take note of the negatively-sloped tangent line to the inverse of f at x = 1.

honestly this problem isnt super super complicated as we need to do is use some multiply tables! :)
since we know that
4*3
= 12
and in this problem
1/4
just means
= 3 months
so
3*3
= 9 months

Answer:
a. ? % of 75 = 5 = 15
b. ? % of 28 = 140 = 500
c.? % of 100 = 40 = 40
