the difference between 2 whole numbers is 66. the ratio of the 2 numbers is 2:5, what are the 2 numbers​
shtirl [24]

Answer:

44 and 110

Step-by-step explanation:

The ratio of the 2 numbers = 2 : 5 = 2x : 5x ( x is a multiplier ) , thus

difference = 5x - 2x = 3x , then

3x = 66 ( divide both sides by 3 )

x = 22

Thus

2x = 2 × 22 = 44

5x = 5 × 22 = 110

The 2 numbers are 44 and 110

Help me out with this problem please!!and (please tell me how you got the answer.)
Sati [7]
The answers are that the number can equal -4 or 1. 

You can find this by setting the number equal to x.

x^2 (The square of a number) + 3x (three times a number) = 4

x^2 + 3x = 4 ---> subtract 4 from each side
x^2 + 3x - 4 = 0

Then you can factor this to find the answers

(x - 4)(x + 1) = 0

Set both equal to 0 and solve.
