Five years ago the total sum of ages of father and son was 40. The ratio of their present age is 4:1 what is the present age of the father

The ratio of their ages being 4:1, the Father is 40 and the Son is 10 years, now.

Step-by-step explanation:

5 years ago 40+5+5

The present age of the father is 40.

Explanation:

40:10

40 - 5 = 35

10 - 5 = 5

35 + 5 = 40

Hope this helped. Have a lovely week!

we need more info to solve this

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
