Answer:

see below

Step-by-step explanation:

The problem statement tells you the ratio of force to area is the same for all pairs. This means, for example, ...

3750/250 = 5625/x = y/420

Simplifying, this becomes the two equations ...

15 = 5625/x ⇒ x = 5625/15 = 375

15 = y/420 ⇒ y = 420·15 = 6300

The values of x and y are (x, y) = (375, 6300). . . . . matches choice C

A mother is three times as old as her daughter, and the sum of their ages

garri49 [273]

Answer:

Step-by-step explanation:

If m = Mother's age and d = daughter's age, we can make the following equations

m = 3d

m + d = 44

Now, using substitution, we can substitute m for 3d in the second equation:

3d + d = 44, 4d = 44, d = 11

Then, we can plug d into the first equation: m = 3(11) = 33
