Plug in -3x-(3)=18
Add three both sides
-3x=21
Divide -3 both sides
x=7

-3x-y=18
-3x-3=18
+3=+3
-3x =21
/-3 =/-3
x =-7
(-7,3)
I hope this helps!!!

Simplify completely 25 w to the sixth power over 10 w to the third power divided by 30 w squared over 5 w.

malfutka [58]

$\cfrac{25w^6}{10w^3}: \cfrac{30w^2}{5w}= \cfrac{5w^3}{2}* \cfrac{5w}{30w^2}= \cfrac{w}{2}* \cfrac{5w}{6}= \cfrac{5w^2}{12}$

Assume equal likelihood for the birth of boys and girls. What is the probability that a four-child family chosen at random will

garik1379 [7]

Each child has a 50% chance to be a girl and 50%chance to be a boy so with 4 children the probability is
$\frac{1}{2} \times \frac{1}{2} \times \frac{1}{2} \times \frac{1}{2} = \frac{1}{16}$

How can I solve this problem?

irina [24]

5x + 5x +3x (like terms)
13x-60=180
180+60=240
240/13=18.4615
X=18.4615

I hope this is correct.
(There are so many different ways to do math problems like this) I hope I could help... sorry if I didn’t.
