Answer:
Yes, she is correct
Step-by-step explanation:
All you really have to do is multiply 1/5 and 3/4. We can separate her backyard in 5 equal parts. In one of those parts, we have her garden, and we break it down into 4 pieces, and make three of those tomato gardens. Now if we break all 5 parts of her backyard into 4 pieces, we can double check our answer, and see that there are 20 pieces, but only 3 have tomatoes. Of course, that's only to double check, but you could also use this method as a model.

Step-by-step explanation:
<u>Step 1: Define</u>
3x² = 8x - 1
<u>Step 2: Rewrite</u>
<em>Put equation in Standard Form</em>
- Subtract 8x on both sides: 3x² - 8x = -1
- Add 1 to both sides: 3x² - 8x + 1 = 0

Answer:
72
Step-by-step explanation:
If you mutiply 7 x 12 you would get 84 and then minus then how much they just ate to the number of how much there were from mutiplying which would be 84-17= 72
