velikii [3]

There are 10 single digit numbers that can be used for each digit.

The first digit cannot be 1 , so that leaves 9 other possibilities.

The last digit must be even, so it can be 0, 2, 4,6, 8 ( 5 possibilities).

The 3 middle numbers can be any digit ( 10 numbers)

To find total combinations multiply all the possible numbers for each digit:

9 x 10 x 10 x 10 x 5 = 45,000 possibilities.

What is the x and the y
Ghella [55]

Answer:

x=5\\\\y=-8

Step-by-step explanation:

Given Equation:

-7x-10y=45\\\\ Equation:1

-3x-5y=25   Equation:2

Multiplying Equation:2 by '2':

-6x-10y=50  Equation:3

Using Elimination Method: Subtracting Equation:1 from Equation:3:

-6x-10y-(-7x-10y)=50-45

-6x-10y+7x+10y=5\\\\

Solving Like terms:

-6x+7x=5\\\\x=5

Put the value of 'x' in Equation:2

-3x-5y=25

-3(5)-5y=25\\\\-15-5y=25

Adding '15' both sides:

-5y=25+15\\\\-5y=40

Dividing by '-5' both sides:

y=40/-5\\\\y=-8

The values of 'x' and 'y' are:

x=5\\\\y=-8
