your question: 

True or false: z=−5 is a solution to the inequality −2|z−3|<−20.

answer: 

-2|z-3|<-20

-------. -----

-2 -2

|z-3|<10

equation 1: equation 2:

z-3<10. z-3>-10

z<13 z>-13

So false, z=-5 is not a solution to the inequality.

hope this helps, have a great day! :)

x = 375 and y = 6300. Option C.

Step-by-step explanation:

From the given data we need to find the value of x and y.

First, we will find out the ratio of area and the force.

$\frac{Area}{Force} = \frac{125}{1875} =\frac{150}{2250} =\frac{175}{2625}$ = $\frac{1}{15}$

So,

$\frac{x}{5625} = \frac{1}{15}$

or, x = $\frac{5625}{15}$ = 375

Again,

$\frac{420}{y} = \frac{1}{15}$

or, y = 420×15 = 6300

Hence,

x = 375 and y = 6300.
