-3(x + 5) = -9
-3x + -15 = -9
-3x - 15 = -9
-3x - 15 + 15 = -9 + 15 (we added 15 to both sides of the equation because now, the 15 on the left side cancels out).
-3x = 6
-3x/-3 = 6/-3
X = -2
So, in conclusion, X is equal to -2.

A stack of cards is numbered 1 to 21. Leilani pulls one card from the stack. What is the best approximation for the probability
arlik [135]

Answer:

The approximation is 0.2( real value is 0.19)

Step-by-step explanation:

In this question, we are to calculate the best approximation if in a pack of cards labeled 1 to 21 , the card selected is a multiple of 5

First we know that the total number of options in our sample space is 21; from 1 to 21

now let’s get the multiples of 5. we have 5,10,15 and 20

The probability of selecting a multiple of 5 is thus; 4/21 . This can be approximately be said to be 0.2 ( actual value is 0.19)

A train travels 25 miles in 20 minutes. What is the train speed in miles per hour?
kenny6666 [7]
60 min = 1 hour

1st we need to know how many times 20 goes in 60 so we will divide.

60 ÷ 20 = 3

Now we will multiply to find the trains speed in miles per hour. 

3 × 25 = 75

SO, the train travels 75 miles per hour. 

Hope I helped ya!!

a picture 10 1/4 feet long is to be centered on a wall that is 14 1/2 feet long. How much more space is there from the edge of t
Zarrin [17]

Answer:

Length from the edge will be =2{\frac{1}{8}} feet

Step-by-step explanation:

To find length we have to conver mixed fraction to improper fraction


The length of the wall = \frac{29}{2}


Length of picture =\frac{41}{4}


First we find the total length of wall remain after picture was hung to the wall.


Length of wall remain vacant =\frac{29}{2}-\frac{41}{4}


Taking LCM and solving we get


=\frac{58-41}{4} =\frac{17}{4}


Total length of wall remain vacant =\frac{17}{4}


As the picture to be centered in wall, therefore space feom one edge of wall will be half that of length remain vacant as the same length to be left vacant feom both sides.


Space from one edge =\frac{17}{4} \times \frac{1}{2}


= \frac{17}{8}

=2{\frac{1}{8}}


Length from the edge will be =2{\frac{1}{8}} feet

Determine which of the four postulates, if any, can be used to prove that the triangles are congruent.
lora16 [44]

The red lines mean the sides with the lines are the same. The red arc means those angles are the same.

Using that information you know the angle where the two same sides connect would also be the same.

So you have one side (S) and 2 angles (A) that are identical.

You can use B. ASA
