Two numbers are in the ratio 5:2 and their sum is 56. Find the numbers. Please plain how to do this

40 and 16

Step-by-step explanation:

Let's say these numbers are 5x and 2x.

Their sum is 56, so

5x + 2x = 56

7x         = 56

x = 8

Now substitute the unknown value with 8.

5 · 8 = 40,

2 · 8 = 16

correct choice is b

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
