Hello from MrBillDoesMath!

Answer:

Suppose the ordered pair is (x.y). Substitute these values in the linear equality to see if it is true,

Example. Consider the point (7, -4). Is it a solution of the linear inequality

3x < 4y - 9?   Let's check to find out.

Check:

Is  3 (7) < 4 (-4) - 9    true ?

Is    21  < -16     -9 =  -25   ??  

NO!

So (7,-4) is NOT a solution of the linear inequality.


Thank you,

MrB

Write a system of equations and solve.

x + y = 10
5x + 10y = 90

Multiply and combine equations

-5x - 5y = -50
5x + 10y = 90
------------------
5y = 40
y = 8
x = 2

There are 2 nickels and 8 dimes in the jar. Hope this helps! :)
