Answer:
The dryer costs $325.
Step-by-step explanation:
Let <em>w</em> represent the cost of the washer and <em>d</em> represent the cost of the dryer.
They cost $587 combined. In other words:

The washer costs $63 less than the dryer. Therefore:

Thus, we have the system of equations:

We can solve it using substitution. Substitute the second equation into the first. Hence:

Combine like terms:

Add 63 to both sides:

And divide both sides by two. Hence:

The dryer costs $325.
Further Notes:
And since the washer is $63 less, the washer costs:

The washer costs $262.
Answer:
3-1 = 2 units is the distance between the points.
The perimeter is about 82 yards
first, the perimeter of the rectangles is 30*2 = 60 (the 7 is not a part of the overall perimeter so we do not need to add it)
the "perimeter" (circumference) of the 2 semi circles = (22/7)*7 = 22by using the formula C = pi*d (2 semi circles of the same diamter = 1 circle)
now just add the 2 answers
22 + 60
= 82 yards
1) the slope for the points (-4,7) and (-7,-15) is -2.
2) The slope for the function b is D) 2/11
Hope this helps!
