Answer:
$425
Step-by-step explanation:
Let washer be w
Let dryer be d
If d =x then w=x +74
x+x+74=924
2x+74=924
2x=850
dividing both sides by 2
x=425 hence d which is the dryer is $425

Answer:
a = 5.5, d = 11/3
Step-by-step explanation:
An arithmetic progression is a sequence of number such that the difference between consecutive numbers is a constant. It is given by:
The sum of fifth and sixth terms is 44
Therefore:
a + 4d + a + 5d = 44
2a + 9d = 44 (1)
The sum of the first n terms is:
Since the sum of the first eighteen terms is thrice the sum of the first ten terms:
18a + 153d = 3(10a + 45d)
18 a + 153d = 30a + 135d
18a - 30a + 153d - 135d = 0
-12a + 18d = 0 (2)
Multiply equation 1 by 6 and add to equation 2:
72d = 264
d = 11/3
Putting d = 11/3 in eqn 2
-12a + 18(11/3) = 0
-12a + 66 = 0
12a = 66
a = 5.5
