Answer:
Step-by-step explanation:
x - 2y = 14
x + 3y = 9
subtract the first equation from the second to eliminate the x terms:
x + 3y = 9
-x + 2y = -14
-----------------
5y = -5
y = -1
x - 2(-1) = 14
x = 12
:::::
y = 2x
5x - y = 9
Substitute 2x for y in the second equation?:
5x - 2x = 9
3x = 9
x = 3
y = 6

At Ivanna's auto shop, it takes her 15 minutes to do an oil change and 24 minutes to do a tire change. Let x be the number of oil changes she does. Let y be the
number of tire changes she does.
Using the values and variables given, write an inequality describing how many oil changes and tire changes Ivanna can do in at most 2 hours (120minutes)
Plzzz help
Answer:
15x + 24y <= 120
Step-by-step explanation:
It takes 15 minutes per oil change, 15x

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
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

Which equation is correct? o 39 x 3 = 30 x 3 + 9x 3
o 39 x 3 = 30 +9x3
o 39 x 3 = 300 × 3+9×3
39×3=30×3+9
39x3=30x3+9x3
117=90+27
117=117
39x3=30+9x3
117=30+27
117=57
39x3=300x3+9x3
117=900+27
117=927
39x3=30x3+9
117=90+9
117=99
So the first one is correct.

Answer:
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]
Find the area of the octagon.
