rewona [7]

Answer:

RS = 5

Step-by-step explanation:

Since R is between Q and S , then

QS = QR + RS , that is

6x - 3 = 3x - 2 + 2x + 1

6x - 3 = 5x - 1 ( subtract 5x from both sides )

x - 3 = - 1 ( add 3 to both sides )

x = 2

Then

RS = 2x + 1 = 2(2) + 1 = 4 + 1 = 5

A forest covers 33,000 acres. A survey finds that 0.8% of a forest is old-growth-tree. How many acres of old-growth-trees are th

natali 33 [55]

Answer:

264 acres

Step-by-step explanation:

Since 33,000 acres is 100%, 330 acres is 1% because 33000 acres divided by 100 is 330 acres. Then if 330 acres is 1%, 33 acres is 0.1% because 330 acres divided by 10 is 33 acres. 1 divided by 10 is 0.1.

Next 33 acres times 8 because 0.8% is eight times bigger than 0.01%. This equals to 264 acres.

Answer:

I am pretty sure it is -$00.14

Step-by-step explanation:

If you do the math that I think I did correctly you would get 14. Since the bagel cost 39 cents less that is what you would be taking from. The orange juice costs 25 cents more so what I think you would do is 39-25.
