Answer:

solve for k,  k=-1

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable

Answer:

k=-1

Step-by-step explanation:

First step: Distribute

Result: -6-3k-6k=6+3k

Second step: Combine like terms

Result: -6-9k=6+3k

Third step: Add 6 to both sides

Result: -9k=12+3k

Fourth step: Subtract 3k from both sides

Result: -12k=12

Final step: Divide by -12 to both sides

Result/Answer: k=-1

The control group in the experiment are the classes where the teacher does not greet the students

A control group in an experiment is made up of groups of people that do not receive the experimental treatment.

The purpose of a control group is to allow the researcher study one variable at a time.

Victor is conducting an experiment on if positively greeting children as they enter the classroom reduces problem behaviours.

The experimental treatment here is positively greeting the students.

The group that do not receive this experimental treatment are referred to as the control group.

At the end of the experiment, Victor would compare the behaviours of the students in the control group with the behaviour of those who were part of the experimental group to see if greeting reduced problem behaviours.

Answer: sqrt 53

Step-by-step explanation:

Sqrt [(2 - - 5)^2 + (6-4)^2] =

Sqrt (7^2+ 2^2) = sqrt 53

The value of x is 108.

The highest common factor is defined as the set of numbers with the highest common multiple. The highest positive integer with more than one factor in the set is HCF.

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

We have been given that the HCF of 90 and x is 18.

And the LCM of 90 and x is 540.

We have to determine the value of x.​

Since the product of two numbers equals the product of their HCF and LCM.

So 90 × x= HCF × LCM

Substitute the values of given data,

⇒ 90×x = 18×540

⇒ 90×x = 9720

⇒ x = 9720/90

⇒ x = 108

Hence, the value of x is 108.

Step-by-step explanation:

The photo is the explanation.

Answer:

the answer is going to be c

The required algebraic expression is c+4

An expression in math is a sentence with a minimum of two numbers or variables and at least one math operation. This math operation can be addition, subtraction, multiplication, or division.

Given that a statement 4 plus c as an algebraic expression

We need to convert it into an expression,

4 = 4

plus = +

c = c

Therefore, arranging it = c+4

Hence, the required algebraic expression is c+4
