16) k = 50

19) r = 33

explanation:

16) -5 squared is 25

and then the two multiplies that 25 which equals 50

19) 121/11 = 11, which is then multiplied by 3 is 33

Step-by-step explanation:

You said the other one would be the last haha just kidding I'm glad to help.

16. \frac{k}{2}=(-5)^2

First, get rid of that parenthesis.

\frac{k}{2}=25

Now multiply both sides by 2 so that you can isolate k

2(\frac{k}{2})=25*2

k=50

19. \frac{r}{3}=\frac{121}{11}

This is a pretty easy one. If you didn't know, 121/11 is actually 11 :)

\frac{r}{3}=11

Simply multiply by 3 to isolate r :)

3(\frac{r}{3})=11*3

r=33

I tryed my best to figure out what all of the numbers were. if i got any wrong then please tell me and i will put the right answer in the comments.

1) 3/5= 5/x   (cross multiply)
     3x=5(5)
     3x=25
       x= 25/3 -or- 8.33

2) 2/4=x/12<span>   (cross multiply</span><span>)
</span> 2(12)=4x
     24=4x
       6=x
3) 10/x=5/9<span>   (cross multiply</span><span>)
   10(9)=5x
       90=5x
       18=x
4) 5/5=x/18</span><span>   (cross multiply</span><span>)
 5(18)=18x
     90=18x
       5=x</span>

Select all of the following that can be a counterexample for the statement below.
Pavlova-9 [17]

Answer:

-2, 3

Step-by-step explanation:

We are given the following inequality:

x + 2 > 7

Solving it, we have that its solution is:

x > 7 - 2

x > 5

So values of x of 5 and lower are counterexamples to this, which means that -2 and 3 are correct options to this question.

12 workers build a wall in 10hours. How long do 5 workers build a wall​
snow_lady [41]

Answer:

24 hours

Step-by-step explanation:

If 12 workers take 10 hours to build a wall, assuming they build at the same rate, it would take one worker 120 hours to build a wall.

By this logic, it would take 120/5 or 24 hours for 5 workers to build a wall
