The sum of two numbers is 136 one number is 51 what is the other number? What are the common factors of these two numbers?
Rom4ik [11]
The sum of two numbers is 136 (sum is what you get when you add two numbers together). If one of the two numbers is 51, and the other number is X, then:

X + 51 = 136

To solve for x we subtract both sides by 51.

X + 51 -51 = 136 - 51
X = 85

The other number is 85.

What are the common factors of these two numbers?
Factors are the numbers that multiply to make the product.

Factors of 51: 1, 51, 3, 17
Factors of 85: 1, 85, 5, 17

The price of an item has been reduced by 40%. The original price was $60. What is the price of the item now?
erik [133]
To reduce the item by 40%, you first need to find the 40% of 60. Multiply 0.4*60 and you will get 24. That is 40%. Now you need to subtract that from the original. 60-24 is 36 dollars and that is your answer.
