Answer:
z = 5
x = 0
x = 1
Step-by-step explanation:
(z - 5)x^2 - (z - 5)x = 0 Take out z - 5 as a common factor
(z - 5)(x^2 - x) Take out x as a common factor
(z - 5)(x)(x - 1) Any one of these could equal 0. There are 3 solutons.
z - 5 = 0 Add 5 to both sides
z - 5 + 5 = 0 + 5
z = 5
===============
x = 0
===============
x - 1 = 0
x - 1 + 1 = 0 + 1
x = 1

The simplified expression for the total amount in dollars Dave has in his pocket is $(6n+50) and when n = 5 then he has $80.
According to the question,
We have the following information:
Dave has one $20 bill, three $10 bills, and the same number of $5 bills and $1 bills in his pocket.
The number of $5 and $1 bills are n.
a) So, we will have the following expression for the total money he has:
1*20+3*10+5n+n
20+30+5n+n
Now, adding the numbers together and the terms with the same variable together:
$(6n+50)
b) Now, when n = 5:
$(6*5+50)
$(30+50)
$80
Hence, the simplified expression for the total amount in dollars Dave has in his pocket is $(6n+50) and when n = 5 then he has $80.

If 8 tomatoes is sold as $2 .then the unit rate is : 2 / 8 =
0.25.
You can multiply 0.25 X 8 to get the exact $2 amount sold for the 8 tomatoes. Which means each tomato is sold as 0.25 cents
the answer is probably sas, but im just guessing cuz there's like no context whatsoever in the picture.
