Summary:
The solution to 2.5 - 1.2x < 6.5 - 3.2x lies in the interval (-∞, 2).
Answer:
This is a system of equations, meaning there are two equations you will need to use. The first equation would be d + n = 35, where d = dimes and n = nickels. The second equation would be 10d + 5n = 250, since each dime is 10 cents and each nickel is 5 cents totaling at 250 cents. To solve for nickels, solve one equation for dimes and substitute the answer into the d in the other equation. If you need any more help with this one I am happy to help.

Answer:
A
Step-by-step explanation:
all we need to do is to plug the point (6,4) in the inequality and see if it satisfies it :
pay attention that here we have x=6 y=4
4<
we simplify we get :
4<4.5-3
4<1.5 which is incorrect so (6,4) is not a solution. moreover
notice that 4 is > than 1.5 so the point lies above the line
thus the answer is : A
you can also solve this problem by graphing the line and plotting the point (6,4) and hence you will notice that the point is above the line
