Answer: with 133.33 acres of trees
Step-by-step explanation:
4 acres of trees, is a 97% decrease of the previous amount.
This means that if the previous amount was X, then 4 acres is 3% (or 0.03 in decimal form) of X, or:
4 acres = 0.03*X
Now we can solve this for X as:
X = 4acres/0.03 = 133.33 acres
The illegal loggers got away with 133.33 acres of trees
782 + 821 = 1,603
2x2 = 4
Answer:
D. (14, 10)
Step-by-step explanation:
Let's use the first equation for this
x = y + 4
Meaning whatever values we are given, x has to be the value of y + 4
So if the y value is 1, the x value has to be 5
A. (6, 10) | 10 + 4 is not 6
B. (9, 5) | 5 + 4 is 9
B is a possible answer
C. (10, 6) | 6 + 4 is 10
C is also a possible answer
D. (14, 10) | 10 + 4 is 14
D is also a possible answer
After going off of the first equation we realize that all of them are possible answers with exception of A, and now we have to base ourselves off of the 2nd equation
2x - 3y = -2
Let's try with B first
2(9) - 3(5) = -2
18 - 15 = -2
B is not the correct answer since 18 - 15 = 3 and not -2
Let's try with C now
2(10) - 3(6) = -2
20 - 18 = -2
C is not the correct answer since 20 - 18 = 2 and not -2
Let's try with D now
2(14) - 3(10) = -2
28 - 30 = -2
D is the correct answer because 28 - 30 = -2
