-2t + 5 <u>></u> -7

you subtract 5 from each side

-2t + 5 <u>></u> -7

<u>     - 5    - 5 </u>

<u>  -2t</u>  <u>></u>  <u> - 12 </u>    then, you divide both side by -2 so you can get t                        by it's self.      

  -2       -2

                          When you divide a number by a number that is negative you flip  your greater than or less than sign.

so,  the answer is t <u><</u> 6 or  A

Ben is making salsa.He needs 1/3 cups of chilies for each bach of salsa.Ben has 5/6 cup green chilies.How many baches of salsa c
FromTheMoon [43]

Answer:

The number of batches Ben can make with 5/6 cup of green chilies is 2\frac{1}{2} batches of salsa.

Step-by-step explanation:

From the question,

Ben needs 1/3 cups of chilies for a batch of salsa.

To determine how many batches of salsa he can make with 5/6 cup of green chilies,

Let the number of batches Ben can make with 5/6 cup of green chilies be x.

Now,

If 1/3 cups of green chilies is needed for 1 batch,

Then, 5/6 cups of green chilies will make x batches

1/3 × x = 5/6 × 1

x = 5/6 ÷ 1/3

x = \frac{5}{6} \div \frac{1}{3}

x = \frac{5}{6} \times \frac{3}{1}

x = \frac{15}{6}

x = \frac{5}{2}

x = 2\frac{1}{2}

Hence, the number of batches Ben can make with 5/6 cup of green chilies is 2\frac{1}{2} batches of salsa.

In a popular tale of wizards and witches, a group of them finds themselves in a room with unmarked doors which change position,
SSSSS [86.1K]

Answer:

Expected number of hours before the the group exits the building = E[Number of hours] = 3.2 hours

Step-by-step explanation:

Expected value, E(X) is given as

E(X) = Σ xᵢpᵢ

xᵢ = each variable

pᵢ = probability of each variable

Let X represent the number of hours before exiting the building taking each door. Note that D = Door

D | X | P(X)

1 | 3.0 | 0.2

2 | 3.5 | 0.1

3 | 5.0 | 0.2

4 | 2.5 | 0.5

E(X) = (3×0.2) + (3.5×0.1) + (5×0.2) + (2.5×0.5) = 3.2 hours

Hope this Helps!!!
