A washer and a dryer cost $597 combined. The washer costs $53 less than the dryer. What is the cost of the dryer?
Volgvan

Answer:

w + d = 797

w = d - 53

Because they are equal, we can take whatever is on one side of the = and replace it for what's on the other side.

d - 53 + d = 797

2d = 850

d = 425

Change<br>2.215(1 and 5 are recurring/repeating decimals)<br>in form of​ a/b
Romashka-Z-Leto [24]

Answer:

Answer:

2.215=2 43/200

Step-by-step explanation:

Showing the work

Rewrite the decimal number as a fraction with 1 in the denominator

2.215=2.215/1

Multiply to remove 3 decimal places. Here, you multiply top and bottom by 103 = 1000

2.215/1×1000/1000=2215/1000

Find the Greatest Common Factor (GCF) of 2215 and 1000, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 5,

2215÷5/1000÷5=443/200

Simplify the improper fraction,

=2 43/200

In conclusion,

2.215=2 43/200
