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

7(y+3)=5y+8<br> Is this <br> A.Solution<br> B.No Solution<br> C. Infinite Solution
faust18 [17]

First, let's use the Distributive Property to make our equation easier to solve. Remember that the Distributive Property says the following:

a(b + c) = ab + ac


Using this, we can multiply the 7 out to the y and 3. This gives us:

7y + 21 = 5y + 8


Now, let's solve for y:

2y + 21 = 8

2y = -13

y = - \dfrac{13}{2}


We can see that there is one solution for this equation because y is equal to one definite value after solving. Thus, our answer is A, one solution.

inna [77]

Answer:

Think about it

Step-by-step explanation:

If you made $20 in 2 hrs you made $10 per hour

To find out how much you make per certain number of hrs multiply $10 by the number of hours

The equation is y = 10x + 0 <-- this is also answer to number 4

10x is the constant of proportionality I think.
