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.

Answer:
50kg
Step-by-step explanation:
K = Keith B = Beth H = Henry
K = 20 + B
H = 2B - 30
K = H
20 + B = 2B - 30
B = 50kg
Answer:
to find the answer, you need to find the measure of the angle on the other side of the 142. and since it's a straight line, those two angles measures are =to 180 (they're supplementary angles). so the measure of that angle is 38 degrees. to find the measure of the remaining angle, you subtract the angle measures you already know from 180 (because the sum of interior angles in a triangle is 180.) to, the answer is:
180-90-38= 52 degrees or A
