So each individual bought one drink and one sandwich. The equation to find the cost is 21 = 3x + 6
Subtract 6 from both sides
15 = 3x
Divide 3 from both sides
x = 5
The price of each sandwich was $dollars.
Think of it, 5 + 5 + 5 = 15 (sandwiches)
15 + 2 + 2 + 2 = 21 (Drinks and the total sandwich amount)
Hope this makes sense, ask if you need more help! :)
Answer: i only know question one so here
The first mathematical error occurred going from line __3__ to line _4___.
Why it is incorrect:
It is incorrect because the minus sign was not properly distributed. Line 4 should be ...
5 -2x +6 ≤ 4x -8
a.
The second mathematical error occurred going from line ___5_ to line 6____.
Why it is incorrect:
It is incorrect because 1 was added on the left and subtracted on the right. The same number needs to be added or subtracted on both sides.
b. Solve the inequality correctly.
5 -2x +6 ≤ 4x -8---------------correct line 4
11 -2x ≤ 4x -8------------ combine constants
19 -2x ≤ 4x ------------add 8
19 ≤ 6x--------------- add 2x
19/6 ≤ x----------- divide by 6
Answer:
5/7 > 1/13. Hence Greater than Symbol will be used to compare the fractions.
Step-by-step explanation:
Given:
Two fractions given are 5/7 and 1/13
We will first calculate each of the fraction and then we will decide which one is greater and which one is smaller accordingly we will assign the symbol for the same.
First we will find the answer for 5/7.
Now dividing the number 5 from 7 we get;
Now we will find the answer for 1/13
Now dividing the number 1 from 13 we get;
From above we can see that 0.714 is greater than 0.076.
Hence we can say that 5/7 is greater than 1/13.
So the symbol used will be greater than > where number 5/7 is greater than 1/13
5/7 > 1/13
I think your answer would be equations or expressions?
The answer: $56.95
Discounted price is the amount of sum that extracted from the original price when buyers receive some sort of leverage from the seller. In this case, discounted price of the ticket is $44 which was $12.95 less than the original price. Then the original price would be:
$44 + $12.95= $56.95
