Answer:
68 plants.
Step-by-step explanation:
Let x represent the number of plants that Reuben bought from the nursery.
We have been given that Reuben bought a whole bunch of plants at the nursery the other day. Right away, five died. So number of plant left would be 
.
We are also told that then our dog dug up 2/9 of them. So number of plants left after dug-up would be 
.
Further a rabbit came and ate ½ of what was left. So number of plants left would be 
.
Since Reuben had only 7 plants left, so we will equate our expression with 7 and solve for x as:
Therefore, Reuben bought 68 plants at the nursery.
To the nearest inch it'll be
d×3.14=63
= 20 inches
Answer:
It's d. -4x^2 + 2x + 2.
Step-by-step explanation:
-4x^2 + 2x + 2.
------------------------
6x + 3 )-24x^3 + 0x^2 + 18x + 6
-24x^3 - 12x^2
--------------------
12x^2 + 18x
12x^2 + 6x
--------------
12x + 6
12x + 6
the slope is 1 and the y intercept is-2
Step 1: subtract x from -3. New equation should be y=-3-x.
Step 2: plug that equation into top equation. Should be 5x + 2(-3-x) = 9.
Step 3: use distribitive properties on 2(-3-x). New equation is 5x - 6 - 2x = 9.
Step 4: combine like terms. New equation 3x - 6 = 9.
Step 5: work it out. Divide 3x and 9 by 3. New equation is x - 6 = 3. Add 6 to -6 and 9. Final eqaution is x = 9.
Step 6: swap 9 for x in second equation. New equation is 9 + y = -3
Step 7: subtract 9 from 9 and -3. New equation is y = -12
: = = -
