The cost to mail a letter is a base charge of $0.42 plus $0.17 for each ounce. write an equation that could be used to find how many ounces a letter that costs $0.93 weighs. (let x represent the number of ounces.)
0.59x = 0.93 0.42x + 0.17 = 0.93 0.59 = 0.93x 0.42 + 0.17x = 0.93

0.42 + 0.17x = 0.93

Step-by-step explanation:

45.36 feet per second

step-by-step explanation:

tyrone travels 30 miles in 58.2 minutes.  

1 mile = 5280 feet; this means he travels

30(5280) = 158400 feet in 58.2 minutes.

1 minute = 60 seconds; this means he travels 158400 feet in

58.2(60) = 3492 seconds.

this gives us the unit rate of

158400/3492 = 45.36 feet per second.
