Need help for 16) and 19) Solve each equation and check. Show all work please

Paladinen [302]

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 :)

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

$r=33$

GalinKa [24]

4+7=11 i.e. The whole.
7/11=28

1/11=4
Goats are 4/11 therefore
4 x 4= Ans
All the animals add up to 44 and if you check w/ 7/11 it is correct.
