Step-by-step explanation: because I had that question

The Range of the given set is 5.

We have been given Bar Chart that shows how many days it took for 12 corn seedlings to emerge.

We know that the Range of data set is the difference between the smallest and largest values

It is a measure of the spread or variability of the data set.

The highest point is 10

The lowest point is 5

The Range = 10 - 5

Range = 5

Therefore, the correct answer is 5.

I’m pretty sure the answer should be 1,710 if not i’m sorry

Answer:

1710 fish

Step-by-step explanation:

Let the number of fish in the lake last year be 'x'

The equation becomes-
x + 15x/100=6210     (This is because 15% of x is added in x to become    
6210... hope you understand)

x + 15x/100 = 6210
115x/100 = 6210
23x/20 = 6210
x = 6210 * 20/23
x = 270 * 20
x = 5400

Therefore- The number of fish last year = 5400


Now, let the number of fish in the lake 2 years ago be 'y'

The equation becomes-
y + 20y/100 = 5400     (Same logic as last time)

y + 20y/100 = 5400
120y/100 = 5400
24y/20 = 5400
6y/5 = 5400
y = 5400 * 5/6
y = 900 * 5
y = 4500

Therefore- Fish in the lake two years ago = 4500 fish

Difference between current and two years ago = 6210-4500
                                                                               = 1710 fish

The ages of John and Sam are 47.34 and 17.66 years respectively.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, John’s age is 12 more than 2 times Sam’s age. The sum of their ages is 65.

Let, The age of Sam be 'x'.

Therefore, 2x + 12 + x = 65.

3x = 53.

x = 17.66.

So, Sam is 17.66 years old and john is (65 - 17.66) = 47.34 years old.

Answer:

b=p/2 -l=54/2-15

= 27 -15=12

so 12 is the breadth

a of rectangle =l x b

15 x 12

= 180

a of garden =180yd

Step-by-step explanation:

The correct statement is a. There are 1,000,000 milliliters in a kiloliter.

A kiloliter is a unit of volume equal to 1,000 liters. One liter is equal to 1,000 milliliters. Therefore, one kiloliter is equal to 1,000 x 1,000 = 1,000,000 milliliters.

The equations that can be used to find the numbers are:

x = 19 - y and x = 5y +1.

Option A is the correct answer.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

We know that the sum of two factors of 48 is nineteen, so we can write an equation:

x + y = 19

We also know that the larger factor, x, is one more than five times the smaller factor, y, so we can write another equation:

x = 5y + 1

Now we can substitute the second equation into the first equation to eliminate x and solve for y:

(5y + 1) + y = 19

6y + 1 = 19

6y = 18

y = 3

Now we can substitute y = 3 into the second equation to find x:

x = 5y + 1

x = 5(3) + 1

x = 16

So the two factors of 48 that add up to 19 are 3 and 16.

Now let's check which system of equations can be used to find the numbers.

a.

x = 19 - y

x = 5y +1

Substituting the first equation into the second equation, we get:

19 - y = 5y + 1

18 = 6y

y = 3

Substituting y = 3 into the first equation, we get:

x = 19 - y

x = 16

So this system of equations can be used to find the numbers.

b.

x = 19 + y

y = 5x + 1

Substituting the first equation into the second equation, we get:

y = 5(19 + y) + 1

y = 96 + 5y

4y = 96

y = 24

Substituting y = 24 into the first equation, we get:

x = 19 + y

x = 43

So this system of equations does not give us the correct solution.

c.

x = y + 19

y = 5x -1

Substituting the first equation into the second equation, we get:

y = 5(y + 19) - 1

y = 94

Substituting y = 94 into the first equation, we get:

x = y + 19

x = 113

So this system of equations does not give us the correct solution.

d.

x = y - 19

x = 5y +1

Substituting the first equation into the second equation, we get:

y - 19 = 5y + 1

-4y = 20

y = -5

Substituting y = -5 into the first equation, we get:

x = y - 19

x = -24

So this system of equations does not give us the correct solution.

Therefore,

The equations are x = 19 - y and x = 5y +1.

2 is 100$ for the party room and 75$ for each person for skates

Step-by-step explanation:

Answer:

1. 2x+5=20

2. 5x+100=175

Step-by-step explanation:

2 represents the cost of each round of pitch and since the number of pitches in unknown we put an x there. 5 is the money it costs to use the batting cage. 20 is the total money they used

5 represents the cost per person for skate rental and number of people is unknown so it is represented with x. 100 is the money it costs to rent the room. 175 is the total money used
