How many 4 digit numbers are divisible by 5? This can be answered by thinking of the combinations of digits. For example, the first three digits could be anything from 100 to 999. There are 900 combinations, because 999-100 plus 1 (to count 999 in, subtracting counts the distance between) and numbers divisible by 5 end in a 5 or a 0, so 900 x2 for 2 combinations is 1800 numbers. Hope this helps!
I don't know the last one but

Actually Welcome to the Concept of the Equations.
1.) Polynomial ==> Binomial
2.) Degree ==> 2
3.) Terms ==> 2
4.) Name ==> Quadratic Equation in two variables.
5.) Coefficient => 7 and 3
X=5
y=6
here’s how i got it:
-6x+6y=6
-6x+3y=-12
multiply the second equation by -1
you will get this:
-6x+6y=6
6x-3y=12
add them up and you will get
y=6
then substitute y in one of the equations and you will get x=5
