x+y=8
2x-y=16
3x+z=18

Answers

Answer 1

Answer:

x+y-8=0

Step-by-step explanation:

It makes the most sense

Answer 2
The answer is (x, y, z)=(8, 0, -6)
You have to substitute the values
x=8-y
2x-y=16
3x+z=18
Then you simplify
2(8-y)-y=16
3(8-y)+z=18
Next you substitute the value of y
y=0
-3y+z=-6
After that you solve the equation
-3x0+z=-6
Then you substitute the value of y
z=-6
Simply
x=8-0
So a possible solution will be 8.
(X, y, z)=(8, 0, -6)
Simply
8+0=8
2x8-0=16
3x8+(-6)=18
The ordered triple is the solution
8=8
16=16
16=18
(x, y, z) = (8, 0, -6)

NOW

RT-RS= 10-2=8=ST

SO THE ANSWER IS

ST+QS=8+4=12

Answer:

You have a plate of 40 cookies. Ten have chocolate chips and 15 have pecans. Of the cookies mentioned in the preceding
sentence, four have both chocolate chips and pecans. You select a cookie at random. What is the probability that your cookie has
chocolate chips or pecans?
(Express numbers in exact form. Use symbolic notation and fractions where needed.)
probability your cookie has chocolate chips or pecans:

Answers

Using Venn probabilities, there is a 0.525 = 52.5% probability that your cookie has chocolate chips or pecans.

What is a Venn probability?

In a Venn probability, two non-independent events are related with each other, as are their probabilities.

The "or probability" is given by:

[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]

For this problem, the events are given as follows:

Event A: Chocolate chips.Event B: Pecans.

From the text, the probabilities are given as follows:

[tex]P(A) = \frac{10}{40}[/tex].[tex]P(B) = \frac{15}{40}[/tex][tex]P(A \cap B) = \frac{4}{40}[/tex]

Hence the "or probability" is given by:

[tex]P(A \cup B) = \frac{10}{40} + \frac{15}{40} - \frac{4}{40} = \frac{21}{40} = 0.525[/tex]

0.525 = 52.5% probability that your cookie has chocolate chips or pecans.

Find the LCM of 17, 11, and 5

Answers

Answer:935

Step-by-step explanation:

Answer: 935 is the LCM of 5, 11, and 17.

Step-by-step explanation:

Firstly, I am going to use the easier method of finding numbers that meet up with each other.

So, by adding the first number to itself and then to the new number, we can use a list-type method. Let's begin.

5, 10, 15, 20, 25, 30, 35, 40, 45..... 920, 925, 930, 935.

11, 22, 33, 44, 55, 66, 77, 88, 99, 110, 121, 132, 143..... 913, 924, 935.

17, 34, 51, 68, 85, 102, 119..... 884, 901, 918, 935.

The list goes on all the way until we reach 935, which in this case, is our Least Common Multiple. This takes quite a while, so you should use an online and/or auto-calculator instead of doing the challenge on your own.

To recap, using the listing method to find LCMs, the LCM of 5, 11, and 17 is 935.

(11/18-4/9)+1/6 pemdas fraction

Answers

Answer:

1/3

Step-by-step explanation:

11/18 - 4/9 + 1/6

= 1/6 + 1/6

= 1/3

The value of the fraction is 1/3.

What is PEMDAS Rule?

PEMDAS rule is the same as BODMAS rule.

PEMDAS is the abbreviation for Parenthesis, Exponents, Multiplication, Division, Addition and Subtraction.

Given fraction is : (11/18 - 4/9) + 1/6

We have a parenthesis (brackets) in the given expression. First solve the operations inside the bracket.

And multiply the fraction 4/9 with 2 on both numerator and denominator.

(11/18 - 4/9) + 1/6 = (11/18 - 8/18) + 1/6

                           = 3/18 + 1/6

There is only an operation of addition left.

Multiplying both numerator and denominator of 1/6 with 3,

(11/18 - 4/9) + 1/6 = 3/18 + 3/18

                           = 6/18

                           = 1/3

Hence the value of the fractional expression given is 1/3.

What is measure 1, 2, 3, 4, 5?

Answers

1 = 27
2 = 27
3 = 27
4 = 27
5 = 126

Answer:

The triangles formed are iscocleles triangles making their bases the same angle measures. Additionally, RST anf RGT are congruent since they are each equal to 1/2 of RQTS

We also know that the interior angles of any triangle add up to 180°

Therefore,

m<R + m<T + 126 = 180

m<R + m<T = 54

Since m<R and m<T are equal, R and T must be equal to 27

m<R=27

m<t=27

Therefore,

m<1=27

m<2=27

m<3=27

m<4=27

m<5=126
