Step-by-step explanation:

Answer:

D

Step-by-step explanation:

The whole number 7 stays constant and in order to find the decimal, divide the numerator by the denominator. So  3 divided by 5 equals .6 so therefore the answer is 7.6

Answer:

(x)   (y)

6   -6

-10   -22

The rule is to subtract 12 from x or to add 12 from y. x - y = 12 or y + 12 = x.

Step-by-step explanation:

32 - 20 = 12

14 - 2 = 12

-6 + 12 = 6

The input is 6 for the output that is -6.

-2 - 12 = -14

-10 - 12 = -22

The output is -22 for the input that is -10.

Answer:

i think it is 87 because

Add Two-thirds to both sides

solution:

x-2/3= 5/6

We have to find how this can be solved for "x" in one step

Remember that,

We we add or subtract same number from both sides of a equation, the equation still remains true

Therefore, from given,

x-2/3=5/6

Add Two-thirds to both sides

x-2/3+2/3=5/6+2/3

x=5/6+2/3

x=9/6

Add Two-thirds to both sides to solve the sum

Answer:

A.

Add Two-thirds to both sides.

Answer:

Just say what you did in your math equation

Answer: points in original figure (-6, 2)

Points in final figure (6, 2)

Step-by-step explanation:

First reflect the figure over the y axis. Then you can see that y is still 2 and that d has now become positive 6

Put those values in as (6,2) for the final figure

Answer:

Three times

Step-by-step explanation

Every time you multiply by 10 the decimal point moves by one value, since it would need to move 3 time to get to 273.22, you would need to multiply it by ten three times.

An equation in two variables that shows the relationship between the time t and the distance d traveled is,

⇒ d = (6/5) t

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expression is,

The elevator rises 5 stories every 6 seconds.

Let the time t and the distance d traveled.

Hence, We get;

Answer:

12ab+24

Step-by-step explanation:

The solution for the expression ( 3/4a x 6b )+ 24 will be 12ab + 24. The correct option is C.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that the expression is  ( 3/4a x 6b )+ 24. The solution for the expression will be calculated as,

Expression =  (3/4a x 16b )+ 24

Expression = ( 48 / 4 ab + 24 )

Expression = 12ab + 24

Hence, the solution of the expression will be 12ab + 24.

Answer:

A linear model (is/is not) the best fit for the data because the residual plot (shows no pattern/shows a pattern) and is (scattered/not scattered).

Step-by-step explanation:

A linear model should be used when you want to view the data as a continuous response. This means that when the data is increasing/describing then the line should be in a uniform pattern.

If you were to look at the residual plot, you can see that the points curve in a pattern, meaning that the point is not scattered which is not good criteria for a residual plot.

Mentioned before, the points on the residual plot are in a pattern, so it’s not scattered as well.
