Step-by-step explanation:
3(1/6+2/9)+(-2)
3(7/18)+(-2) working what is in parenthesis.
7/6-2 reduced the numbers ( 3 and 18) with greatest common divisor . which is 3
-5/6 calculate the difference
Answer:
8 years
Step-by-step explanation:
100e^(.05t) = 150 . . . . . a better model of the situation
e^(.05t) = 150/100 . . . . divide by 100
0.05t = ln(1.5) . . . . . . . . take natural logs
t = ln(1.5)/0.05 ≈ 8.11 . . . . divide by the coefficient of t

Answer:
768 cubic feet
Step-by-step explanation:
16 * 24 = 384

1920-1152 = 768
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.
