The school auditorium has 438 seats. There are 18 rows of seats. What is the best estimate for the number of each seats in each row?

Answer:

D. 116

Step-by-step explanation:

Let the grasshoppers with a white marking be 2x.

Let the grasshoppers without a white marking be 3x.

2x + 3x = 290

5x = 290

x = 290 / 5

x = 58

The grasshoppers with a white marking

= 2x

= 2 ( 58 )

= 116

Answer: 1/35

Step-by-step explanation:

I just did the assignment on ck-12 and got it right.

The probability of removing 4 marbles without replacing and getting exactly 3 blue is 1/35.

Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.

The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.

A bag contains 10 colored marbles - 4 red, 4 blue, and 2 green.

The probability of removing 4 marbles without replacing and getting exactly 3 blue.

= 1/35

Answer: the answer will be -15.5, but this number is not in the choices given, so I guess you made a mistake while writing the equation

Step-by-step explanation:

6q+8=-9-76

6q+8=-85               Subtract 8 from both sides

6q=-93                   Divide both sides by 6

q=-15.5

x = 6 and y = -1

Step-by-step explanation:

hope this helps

Answer:

x= 6 and y= -1

Step-by-step explanation:

-2x - 9y = -3

-7x - 9y = -33

I'm going to be solving by elimination. However, you can solve using substitution as well.

So the first step is to eliminate one of the variables. In my opinion, what's easiest is eliminating the y variables. To eliminate you want to variables (that are the same) to equal 0 and cancel out. To do this, all I have to do is subtract. When I subtract I get 0 as shown below. I will also subtract the other variables and numbers in the equations because that's how elimination works.

-2x - 9y = -3

-7x - 9y = -33

5x = 30

-2 - (-7)=5 and -3 - (-33)= 30

There's no solution for the y variable because -9 - (-9)=0, which cancels out so it doesn't have to be written.

after that you get x=6 because you divide by 5 on both sides.

All that's left is to plug in 6 to one of the equations:

-2(6) - 9y= -3

-12 - 9y= -3

+12         +12

-9y= 9

Divide both sides by -9 to get y= -1

Answer:

200 m^3

Step-by-step explanation:

1) find the side of the base

side = 40 : 4 = 10 m

2) find the base area

base area = side^2 = 10^2 = 100 m^2

3) find the Volume

V = (base area x height)/3 = (100 x 6)/3 = 200m^3

Convert the mixed fraction to an improper fraction

to convert to improper fraction, take the following steps :  

1. Multiply the whole number  by the denominator

2. Add the numerator to the answer gotten in the previous step

3. divide the number gotten in the previous step by the denominator  

= 1/3 x 61/2 = 61/6

convert to mixed fraction

Answer:

1.        42

2.       46

3.      0

Step-by-step explanation:

math

Answer:

1. x = 42

2. y = 46

3. z = 0

Step-by-step explanation:

1. 45 + x = 87

         subtract 45 from both sides

  x = 42

2. y - 31 = 15

         add 31 to both sides

  y = 46

3. 5z = 0

         divide 5 from both sides

  z = 0/5

         since any fraction with a numerator of 0 is equal to 0, we get

  z = 0
