1/3 inverted is 3/1 or 3
The answer is no because she only got information from one group and she should get the input of other 7th graders
(<span>4/9)/x = 12 </span>
<span>12x = 4/9 </span>
<span>x = 4 / (9•12) = 1 / (9*3) = 1/27</span>
Answer:
1,2,3,4,6,8,9,12,18,24,36 and72
Answer:
B
Step-by-step explanation:
THis is a single equation with a single variable [y].
We can separate the variable in one side and the numbers to another and solve for y. Shown below:
3y + 4 = -2
3y = -2 - 4
3y = -6
y = -6/3
y = -2
THus, this equation has only 1 solution. B is correct
