Easy I guess ..
I ll try to help ..
Here we go ..
The cards you have is N
The cards he has is n
<span>you have 3 times the number of cards he has
This means N=3n
</span><span> you only have 80 more football cards then he does
This means N=n+80
But we already know that N=3n
So 3n=n+80
which is 2n=80
n=40
So your friend has only 40 cards and you have 3*40= 120 cards
Best luck

Answer:
y=3x-9
Step-by-step explanation:
Hi there!
we are given a point (4,3), and a line (y=-1/3x+4)
Perpendicular lines have slopes that are negative and reciprocal; if they are multiplied together, the result is -1
first, let's find the slope of the new line.
we can find it with this formula: (m=slope)
-1/3m=-1
multiply both sides by -3
m=3
here's our equation so far, written in y=mx+b form, where m is the slope and b is the y intercept
y=3x+b
we need to find b
Because the line passes through the point (4,3), we can use it to find b
substitute x as 4 and y as 3
3=3(4)+b
multiply
3=12+b
-9=b
substitute into the equation
<u>y=3x-9</u>
Hope this helps!

There are 6 smaller bars
Explanation: 2 1/4 lb. to ounces is 36 ounces. Divide it by 6 and it makes 6 smaller bars.
We have been given that a friend has tickets to a concert and who selects 2 of them at random to give to you and we are also told that your friend has 13 tickets of which 5 are in the front row and 8 are in the tenth row.
We are asked to find out probability that both of the tickets you receive are in the front row.
In order to find out the probability that both of the tickets you receive are in the front row we will use probability formula.
Now let us find out total number of possible outcomes,
Now we can find out probability of getting both tickets in the front row by substituting our values in probability formula.
