The sum of two numbers is 10. the difference between the two numbers is 4. what is the smaller number?

The smaller number is 3

Step-by-step explanation:

x+y =10

x-y =4

We can use elimination to solve this system

x+y =10

x-y =4

2x = 14

Divide by 2

2x/2 = 14/2

x = 7

Now we need to find y

x+y =10

7+y =10

Subtract 7 from each side

7-7+y = 10-7

y = 3

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,
