5.Which equation corresponds to the following statement?
An author writes 22 pages of her book each week. She has already written 58 pages and expects to have 280 pages in her first draft. How long will it take the author to finish her first draft?
22w+58=280
22w+280=58
58w−22=280***
58w−280=22
[if u have the correct answers pls tell me!]
1. The rate of change in this word problem is the cost of gas per gallon, which is $2.78.
2. The specific quantity in this word problem is the number of trees already planted, which is 11.
3. The variable in the given equation is x.
4. The initial quantity in the given equation is x.
5. The equation that corresponds to the given statement is 58w - 22 = 280.

1. G = 18/2.78 =
#1. number of gallons = 18/2.78 =
#2. Trees still to be planted = 32-11 = 21
at a rate of 3 trees/hour , this will take 21/3 or 7 hours
#3. in 7x−3=32, clearly the variable is x
#4. "For the given equation, identify the initial quantity." For the given question, I have no idea what that is supposed to mean.
#5. If she writes for w more weeks at 22 pages per week, clearly
22w + 58 = 280
Looks like you have lots of review and studying ahead of you
