(4/x - z/y=0) <br> (10/x+z/y=0)
galina1969 [7]

Answer:

Some of the other answers are good examples of solving a system of three equations in three unknowns, which is what this problem is asking. Though the simplest way to solve this problem is actually to notice that, if we sum the three equations, we get:

 

   X + Y = 10

   X + Z = 20

+  Y + Z = 24

----------------

2X + 2Y + 2Z = 54

 

Factoring out the 2, we have 2(X + Y + Z) = 54, and dividing both sides by 2 reveals that X + Y + Z = 27.

Step-by-step explanation:

hopefully this helps

here are the numbers of 15 people ate out last month. 6,5,5,3,5,4,3,6,4,3,6,5,3,7,6 find the modea of this data set​
Taya2010 [7]

Answer: 3 and 5

Step-by-step explanation: The mode is the number that appears most frequently in a data set.

Although it's optional I recommend writing these integers from least to greatest so it will be easier to see what number occurs most frequently.

Notice that there are two numbers (3 and 5) that appear most often (and the same number of times) which means the data set has two modes. When a data set has two modes, this is called bimodal.

What is the first term, common difference, and 16th term
strojnjashka [21]

Answer:

The 1st term is -67

Step-by-step explanation:

I. When Sn = \frac{n}{2}(a_{1} +  a_{n})

   If  Sn = 124, n = 8 and a_{n} = 98

                124 = 8/2(a + 98)

                124 = 4(a + 98)

                124 = 4a + 392

                124 - 392 = 4a

                -268/4 = a

                -67 = a_{1}

Hope that help :D
