Answer:
Point D
Step-by-step explanation:
First set it up so that -x-5=1
Then solve for X
-x=6
Divide by negative 1 since we cannot have a negative x
x=6
If the area decreases by 8.5%, that leaves 100-8.5, or 91.5% of the forest remaining. So, at the end of 15 years, you have:
(.915)^15=.2638, or 26.38% of the forest left.
.2638 x 4200=1108 km² of the forest remains

Eliminate (I) "all bookstores in California," because we're choosing a SAMPLE, not an entire population of stores.
Keeping this in mind, we'd not choose "Internet bookstores" unless it's clear that we're sampling these stores, not looking at all of them.
This leaves only "randomly selected children's bookstores." Even now I'm not comfortable, because this choice focuses specifically on children's stores (instead of on bookstores in general).
Answer:
130
Step-by-step explanation:
This is a ratio problem. There are 6 minutes per 1 minute of television. We are looking to find how many minutes for television. Since we know he rode his bike for 780 minutes, and that 6 minutes of biking is equal to 1 minute, we can divide 780 by 6 to receive 130 minutes of television.
Answer:
x = 15
LN and MO both equal 43
Step-by-step explanation:
LN and MO are diagonals in rectangle
Diagonals of a rectangle are congruent Hence, 4x - 17 = 2x + 13
Now we solve for x
4x - 17 = 2x + 13
Add 17 to both sides
4x = 2x + 30
Subtract 2x from both sides
2x = 30
Divide both sides by 2
x = 15
Now we want to find the values of LN and MO
To do so we substitute 15 for x in it's given expression ( note: because LN = MO we only need to do this process once )
LN = 4x - 17
Substitute 15 for x
4(15) - 17
Multiply
60 - 17
Subtract
LN and MO = 43
