Answer:
475
Step-by-step explanation:
Let's call the dryer price is x
Then, the price for the washer is 53 more than the dryer, it would be: x+53
Total price of washer and dryer = 1003
We get the equation:
x+(x+53) = 1003
2x + 53 = 1003
2x + 53 - 53 = 1003 - 53
2x = 950
x = 475
The dryer price is 475
Extra: you can find the cost of the washer by using x+53 = 475+53 = 528
Answer:
The length of BC is 17
Step-by-step explanation:
When we construct a triangle with the data, we will end up a isosceles triangle.
In a isosceles triangle , we know that tow angles and two sides are equal
The questions states that

Then sides AC and AB are also equal
On equation their values
2X - 8 = X+9
2X = X + 9 +8
2X = X + 17
2X - X = 17
X = 17
The length of BC = X = 17
