Answer:
The total cost of the lunch including the tip is $15.21.
Step-by-step explanation:
To find the total cost of the lunch including the tip, first, you need to calculate 17% of the price of the lunch as the statement indicates that that is the tip Joseph leaves the waiter:
$13*17%=$2.21
Now, you need to add that amount to the price of the lunch:
$13+$2.21=$15.21
According to this, the answer is that the total cost of the lunch including the tip is $15.21.

Answer:
(3,8)
Step-by-step explanation:
y - 5 = x
4x - y = 4
Since y-5 = x, substitute y-5 in place of x in the second equation:
4x- y = 4
4(y-5) - y = 4
4y - 4*5 - y = 4
3y - 20 = 4
3y = 24
y =8
Solve for x:
y - 5 = x
8-5 = x
3 = x
Check:
4x - y = 4
4(3) - 8 = 4
12 - 8 = 4
4 = 4
Check
y - 5 = x
8 - 5 = 3
3 = 3
Check!

Step-by-step explanation:
Here is your answer:
7. 3×1=3
7×1=7
2. 5×1=5
7×1=7
=5 -2/7
Step one: write the equation
Step two: find the common denommarator (which is 7)
Step three: subtract 3-5= which equals to negative 2
Step four: subtract the whole numbers ( 7 and 2) which gives you five
Your answer is...
5 -2/7
