Answer:
D(-2,0) E(-2,2) F(-5,2) G(-5,1)
Step-by-step explanation:
i believe that's correct
Okay. So we will solve this by seeing how many feet is in one second. The model airplane flies 22 feet in one second. I can tell you that the model airplane does fly 1,320 ft per minute, because 22 * 60 equals 1,320, not 1,056 ft per minute. It travels 15 miles an hour, because there are 5,280 ft in one mile. When you multiply 1,320 by 60, you get 79,200 ft. Divide that number by 5,280 and you get 15 miles, not 12 miles per hour. All of the unit rates equivalent to the speed are 15 miles an hour and 1,320 ft per minute.

Step-by-step explanation:
You sure seem to be asking a lot of questions lately. I'd like to see that you've been trying with these problems at least because if you can't get that first one it's almost like you missed the whole lesson.
1. 20 = 4b + 7 + 5
Add the 7 and 5.
20 = 4b + 12
Subtract 12 from each side.
8 = 4b
Divide each side by 4.
2 = b
2. 7 = 6k - 7k
6k - 7k = -1k. (the k acts as a sort of unit)
7 = -1k
Divide each side by -1.
-7 = k
3. 3.23 - 2m = 3 - 2(5m - 2)
Distribute the ×-2 to each term inside the parentheses.
3.23 - 2m = 3 - 10m + 4
Add the 3 and 4.
3.23 - 2m = 7 - 10m
Add 10m to each side.
3.23 + 8m = 7
Subtract 3.23 from each side.
8m = 3.77
Divide by 8.
m = 0.47125
4. -88/45=1/3r+2/5r
To get rid of the fractions, let's multiply everything by 45.
-88 = 15 + 18r
Subtract 15 from each side.
-103 = 18r
Divide by 18.
-103/18 = r
As a mixed number, r = -5 and 13/18
As a decimal, r = -5.7222...
