Just explaining instead of using x for the variable I'm going to use t just so u don't get mixed up with the multiplication symbol and the variable.But on your paper you must use d or else you won't receive full credit.
15tx4>50
On this I can't add a greater than and equal to symbol, but that greater than must have a line under it to represent greater than and equal to. Hope this helps
Answer:
Step-by-step explanation:
Given that:
Number of seats sold is 180 with ticket price $200.
Number of seats decreases by one when the ticket price is increased by $3.
To find:
The formula for the number of seats sold (S) when the ticket price is P dollars.
Solution:
It is linear dependency of number of seats sold, S on ticket price, P.
It can be written as:
Where 
is the constant of proportionality and
is a constant.
Now, putting the given values:
...... (2)
Subtracting (1) from (2):
Putting the value in (1):
Therefore the equation becomes:
Answer:
Step-by-step explanation:
You are multiplying the identity matrix by another matrix.
The effect of multiplying
1 0 0
0 1 0
0 0 1
by another matrix of the same dimensions is nil...nothing happens. So, the answer to this problem is the first matrix itself. Just copy it down.
D it’s literally in that order
let a be aluminum and g be gold and k how many times:
2*10⁻¹mg a+ 6*10¹mg g= 154 lb
so a=kg
k=a/g
k=2*10⁻¹/6*10=1/300
a=1/300g
so Aluminum is 1/300 of gold.
