A washer and a dryer cost $790 combined. The washer costs $90 more than the dryer. What is the cost of the dryer?

The dryer would cost #350.

Step-by-step explanation:

With this kind of equation, you need to budget out steps.

Take away the $90 from the $790 so that the washer and dryer cost the same. You'll get $700. Divide $700 by 2 and you get $350.

Hope this helps! :)

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
