First you do distributive property.

2c + 8 = 0

A washer and dryer cost $841 combined. The washer cost $59 less than the dryer. How much does the dryer cost?

konstantin123 [22]

Answer:

dryer cost = $450

Step-by-step explanation:

Given that:

washer + dryer = $841 ---- eq1

As washer costs $59 less than dryer So,

Dryer - $59 = washer

putting in eq1

Dryer + dryer - $59 = $841

2 dryers = $841 +$59

Dryer = $900/2

Dryer = $450

So the cost of washer will be:

washer = dryer - $59

Washer = $450 - $59

washer = $391

Answer:

Approximately 11.5 units.

Step-by-step explanation:

We need to find the side opposite to ∠W. We are given the two angles ∠W and ∠X. We are also given that Side X is equal to 7. Therefore, we can use the Law of Sines.

Now, like last time, use the Law of Sines:

$\frac{\sin(V)}{v}=\frac{\sin(W)}{w}=\frac{\sin(X)}{x}$
