Answer:
x (Falafel) = $5.50
y (Turkey BLT) = $7.50
z (Paninis) = $6.00
Step-by-step explanation:
Step 1: Write out systems of equations
5x + 15y + 20z = 260
8x + 18y + 14z = 263
12x + 16y + 12z = 258
There are multiple ways to solve for this systems of equations. I will use an augmented matrix for this:
Top row: [5 15 20 | 260]
Middle row: [8 18 14 | 263}
Bottom row: [12 16 12 | 258]
We find RREF form of the augmented matrix to find our answers:
Top row: [1 0 0 | 11/2]
Middle row: [0 1 0 | 15/2]
Bottom row: [0 0 1 | 6]
And we have our answer!
Answer:
31/40
Step-by-step explanation:
Given that:
Fraction of the trail walked intulally = 9/10
Fraction of the trail walked back = 1/8 before stopping to rest
His current distance from the beginning :
Distance walked initially - distance walked back
9/10 - 1/8
The L. C. M of 10 and 8 = 80
Hence,
9/10 - 1/8
= (72 - 10) / 80
= 62 / 80
= 31 / 40
Hence, his rest point or position is 31/40 from the beginning of the trail
Answer:
Following are the responses to the given question:
Step-by-step explanation:
When x is squared, it's going to be bigger by the conclusion because the larger the faster. 
consistently exceeds 
, regardless of the price of X.
5x+3 is always 3 more so than 5x.
In particular, this can be classified according to its pathways 
So can alternatively just say "eventually," which means because when x really is big, you need to find one another's values. Then just select x=100, then plug it into every single other. To confirm this order:
So, the ascending order must be the right order!
The simplified expression of 
is 
<h3>How to simplify the expression?</h3>
The expression is given as:
Expressions raise to power 0 is 1.
So, we have:
Apply the law of indices to expression with common base
Evaluate the sum and difference
Remove the bracket
Hence, the simplified expression of is
