x=2

Step-by-step explanation:

the picture above shows how to go through the equation. I used PEMDAS

Answer:

2.

Step-by-step explanation:

5x + 2(11-1) = 30

First, solve the ones inside the bracket:

11 - 1 = 10

Next, multiply the number inside the bracket by the number next to bracket:

2 × 10 = 20

The equation will now be:

5x + 20 = 30

Since 5x and 20 are not like terms, carry +20 over to the other side making it 30 - 20:

5x = 30 - 20

5x = 10

Now, divide both sides by the coefficient of x (5):

5x/5 = 10/5

x = 2

The answer to the equation is 2.

Answer:

462.5 pages

Step-by-step explanation:

You find out how many books she reads in 1 day then you can multiply it by 5 to get 5 days.

If she reads 185 in 2 days. Divide 185 by 2 to get 1 day.

185/2 = 92.5 pages

Now multiply 92.5 by 5 to get how many pages she read after 5 days.

92.5 x 5 =    462.5 pages

Answer:

A

Step-by-step explanation:

Process of elimination shows that the most reasonable answer is A.

Answer:

a.) they have the same slope

b.) they have different y-intersepts

c.) in the slope-intercept formula y = mx + b, m is the slope and b is the y-intercept. since the two equations have the same slope but different y-intercepts we can infer they are parallel.

Answer:

50%

Step-by-step explanation:

if 2 is an option, then that is 1/8 probability

and the numbers greater than 5 are 6, 7, and 8

so that is 3/8

3/8 + 1/8 = 4/8 = 1/2 = 50%

Step-by-step explanation:

Let the number be x, and we have equation:

The number is -1

Answer:

-1

Step-by-step explanation:

"a number" = x

-- "Two more than 16 times a number." | 16 times a number means "16x" | Two more than just means add 2.

(16x + 2)

-- "Is the same as" means equals.

(16x + 2) =

-- 21 less than the product of -7 and the number | The product of -7 and the number means "-7x" | 21 less than means subtract 21.

(16x + 2) = (-7x - 21)

-- solve for x.

(16x + 7x) = (-21 - 2)

-- combine like terms.

23x = -23

-- Divide.

x = -1

How many plates are on the table as it results in only one value with no variability

Step-by-step explanation:

D) How many plates are on the table? is not a statistical question because it does not involve the collection or analysis of numerical data.

A statistic is a piece of data derived from a subset of a population. It's the inverse of a parameter — census data, which polls everyone.

Statistics is a method of comprehending data collected about us and the world. For example, if you send a parcel through the mail, it is logged in a massive database.

How many plates are on the table? is not a statistical question because it does not involve the collection or analysis of numerical data.

A statistical question involves the collection and analysis of numerical data in order to make inferences or draw conclusions about a larger population.

The other questions (A, B and C) all involve the collection and analysis of numerical data and are therefore statistical questions.

Hence, the correct answer would be option (D).

Answer:

Both lines have a slope of 5, therefore they are parallel lines.

Step-by-step explanation:

The equation of line L₁, is y=5x+1 The equation of line L₂ is 2y-10x+3=0 Show that these two lines are parallel.

As we know, the Parallel lines have equal slopes

The slop intercept form is y = mx + c

Where m is the slope and c is the y-intercept.

Consider the line L₁,

y = 5x + 1 is in the slop intercept form where slope m = 5

Now consider the line L₂.

Write L₂, 2y-10x+3=0 into slope-intercept form

[tex]2y=10x-3[/tex]

[tex]y=5x-\frac{3}{2}[/tex]

The slope of the lines L₂ is m = 5.

Since both lines have a slope of 5, therefore they are parallel lines.

Step-by-step explanation:

not sure what class this is for but I\ll try. Each traveller has a 21 km drive so their fare should be equal.

method 1) each traveller can pay for 21 km worth when they get out

method 2) Curly can pay the full fare and Andy and Bob can pay him back later (they're brothers so this should be easy to manage)

Answer: 23.2 miles per hour

Step-by-step explanation:

He ran 100 meters in 9.63 seconds.

First convert the number of meters he ran to miles:

= 100 * 3.28

= 328 feet

= 328/5,280

= 0.062121212 miles

Convert the seconds to hours:

= 9.63 / 60

= ‭0.1605‬ minutes

= ‭0.1605‬/60

= ‭0.002675‬ hours

Speed in miles per hour is:

=  0.062121212 / ‭0.002675

= 23.22

= 23.2 miles per hour

Answer:

Explanation: the ratio 2:4 can be reduced to 1:2, where the number of girls corresponds to the 1 and the number of boys corresponds to the 2. If there are 14 girls, then there must be 28 boys (14 x 2 = 28). Now to get the total number we need to add the total number of boys and girls together. So 14 + 28 = 42

Answer:

40%

Step-by-step explanation:

6 apples out of 15 fruits = [tex]\frac{6}{15}[/tex]

[tex]\frac{6}{15}[/tex] is equivalent to [tex]\frac{2}{5}[/tex]

[tex]\frac{2}{5}[/tex] is equivalent to 40%

So your answer is 40%
