Answer:

Step 1) She should have added 25 to each side

Step-by-step explanation:

Since there is a -25 in the original equation, to properly cancel it out, she should have added it to both side, not subtracted. This would ensure that the -25 on the left of the = is cancelled out.

Answer:

Step 1: She should have added 25

Step-by-step explanation:

The second step shows that Erica wanted the result that -25 would disappear from the left side of the equation. However, by subtracting 25, she would end up with -5x - 50 on the left.

To make the sum of -25 and some number be zero, the added number must be the opposite of -25. That is, 25 must be added (to both sides).

In the attachment, the sum in the red rectangle is -50, not 0.

I cant believe how bad my brother, Reuben, is at growing things. He bought a whole bunch of plants at the nursery the other day.

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 $x-5$ .

We are also told that then our dog dug up 2/9 of them. So number of plants left after dug-up would be $\frac{2}{9}(x-5)$ .

Further a rabbit came and ate ½ of what was left. So number of plants left would be $\frac{\frac{2}{9}(x-5)}{2}=\frac{2}{9\times 2}(x-5)=\frac{1}{9}(x-5)$ .
