Answer:
i think the answer is 15
Step-by-step explanation:
four $20 bills would equal $80
$80- $44 because of materials gives you $36
$36 divided by 2.50 equals 15
i hope this makes sense :)
Hey there, Xs4etsmith!
The correct answer would be the second option.
To solve for this system of equation, we need to make both equations equal to each other but
first we need to make each equation equal to
0.
So,

goes to

(I subtracted

from both sides)
And

goes to

(I subtracted

from both sides)
Now we can make them equal to each other.

(I subtracted y from both sides to cancel it)
(I subtracted x from both sides)
(I added 3z to both sides to isolate x)
Now, we replace the value of

for

and solve

(Distribute)

(Add

to both sides)
So

is equal to

Let's try the second equation


(Add

to both sides)
The value of

would be

and when solving both equations, we get the same value for

which is

Answer:
inverse
Step-by-step explanation:
y = k/x indicates inverse variation, which is the same as xy = k
in this particular problem, k = 8
The numerator (top number of the fraction) is adding up by odd numbers in order.
From 1/40 to 4/40 you add 3, from 4/40 to 9/40 you add 5, from 9/40 to 16/40 you add 7, and from 16/40 to 25/40 you add 9.
The next number to add would logically be 11. So from 25/40 you would go to 36/40.
36/40 is your next fraction.
Answer:
Sorry, it's actually the third one, 4.8 feet
Step-by-step explanation:
First, you divide the length of the family room tv by the length of the tv in Louise's room
5 divided by 1.5 equals 3.33
Then, you divide the width of the family room tv to get the width of Louise's tv
3 divided by 3.33 is 0.9
Now, you follow the formula for perimeter.
(0.9 + 1.5) x 2 = 4.8
The perimeter of Louise's tv is 4.8 feet.
