Answer:
4 bags of oranges
Step-by-step explanation:
First, we need to find out how much each bag of oranges costs so we divide.
$4.20 divided by 6 equals 0.7 which means that each bag of oranges costs $0.70.
Next we need to find out how much Ayden spent on oranges so we divide 0.70 by 2.80
2.80 divided by 0.70 equals 4.
This means that Ayden bought 4 bags of oranges.
Hope this helps!

Step-by-step explanation:
<h2>
Hello!</h2>
The correct option is:
C.
<h2>
Why?</h2>
To find which of the given options are not the result of a substitution in the given system, we need to isolate the variable in function of the other variable, and then substitute it.
So, substituting and discarding, we have:
- First equation:
Isolating "y", we have:
Then, substituting it into the second equation, we have:
We have that it's a result of a substitutiong in the following system (option A)
- Second equation:
Isolating "y", we have:
Then, substituting it into the first equation, we have:
Have a nice day!
Answer:
13.71 m
Step-by-step explanation:
Draw the tunnel so the width marks the zeroes at (-12,0) and (12,0)
then y = a ( x+12)(x-12) is the equation..
..to calculate 'a' sub in the point 9, 6 (where the width is 18)
6 = a ( (9+12)(9-12) shows a = -2/21
y = -2/21 (x+12)(x-12) Max is when x = 0
-2/21 ( 12)(-12) =<u> 288/21 = 13.71 m </u>
Answer:
x = 10.75
Step-by-step explanation:
To find the value of x, we need to know the equation for the perimeter of a rectangle. This equation is:
P = 2L + 2W
Where P is the perimeter, L is the length, and W is the width.
We are given P = 84, L = 3x -1 , and W = x. Now we just plug these values in and solve for x.
P = 2L + 2W
84 = 2 ( 3x - 1 ) + 2 ( x )
84 = 6x - 2 + 2x
84 = 8x - 2
86 = 8x
86 / 8 = x
43 / 4 = x
(40 + 3) / 4 = x
10.75 = x
Hence, the value of x = 10.75.
Cheers.
