Write an expression that is equivalent to 3k - 18

Answers

Answer 1

Answer:

3(k-6)

Step-by-step explanation:

I did it on i-Ready and got it right!

A common factor of 3k and 18 that is greater than 1 is 3.

An expression that shows 3k minus 18 is 3(k)-3(6).

Answer 2

An expression that is equivalent to 3k - 18 can be written as follows:

3(k - 6)

Given is an expression 3k-18 we need to an expression that is equivalent to it,

Let's break it down to understand why this expression is equivalent to 3k - 18:

Distributive Property: The expression 3(k - 6) can be expanded using the distributive property, which states that for any real numbers a, b, and c: a(b + c) = ab + ac.

In this case, a is 3, and b is k while c is -6. So we can apply the distributive property as follows: 3(k - 6) = 3k + 3(-6).

Simplification: The term 3(-6) can be simplified to -18, so the expression becomes 3k - 18.

Therefore, the expression 3(k - 6) is equivalent to 3k - 18 because both expressions yield the same result when evaluated for any value of k.

Y = -3x -1

Step-by-step explanation:

Y = mx + b

Y is the y intercept (x,y) always graph on y axis

M is the slope

Answer:

Step-by-step explanation:

use the point slope equation.

y-y1 = m(x-x1)

the point is (x1, y1) = (2, -1)

the slope is m = -3

y+1 = -3( x-2)

y = -3x +6-1

Swim floats are on sale at sam’s shop. They are marked 30% off of the original price of 18.00. How much will the float cost

Answers

Answer:

the cost is now $5.40

Step-by-step explanation:

if 18.00 is 100%, and we need to find the new price we need to make 30% into a decimal. which is 0.3. then we multiply 0.3 times 18.00, and that equals 5.4, but since we are dealing with money the answer would be $5.40.

we multiply if we are trying to find the new amount and we divide to find the old amount.

What can you conclude from the diagram

Answers

Answer:

You can conclude from the diagram that m∠P is less than m∠N ⇒ A

Step-by-step explanation:

In any triangle, you can arrange the lengths of the sides according to the measure of the opposite anglesIn any triangle, you can arrange the measure of the angles according to the lengths of the opposite sides

Example:

In ΔABC, if the arrangement of the sides is AB < BC < CA, then the arrangement of the measures of the angles is m∠C < m∠A < m∠B

Let us use this fact to solve the question

→ In ΔKNP

∵ KP = 8 units

∵ KN = 6 units

∵ 6 < 8

∴ KN < KP

∵ ∠P is opposite to the side KN

∵ ∠N is opposite to the side KP

∵ KN < KP

→ By using the fact above

∴ m∠P < m∠N

∴ m∠P is less than m∠N

∴ You can conclude from the diagram that m∠P is less than m∠N

2x – y=1

Answers

Did it step by step , hope it helps !

The value of x and y  for the given equation by elimination method are 1 and 1 respectively.

Elimination method for solving the system of equations;

The elimination method is the process of eliminating on of the variables in the system of linear equations using the addition or subtraction methods in conjunction with multiplication or division of coefficients of the variables.

According to the given question

We have two equations

[tex]2x -y =1...(1)[/tex]

[tex]x+3y-4=0...(2)[/tex]

Multiply equation (1) both the sides by 3

[tex]6x - 3y =3...(3)[/tex]

Adding equation (2) and (3)

[tex]6x+-3y+x+3y -4 =3\\7x =7\\x =1[/tex]

Substitute

x =1,  in either 2x -y =1 or x + 3y -4 =0

2(1) - y =1

⇒ -y = 1 -2

⇒ -y = -1

⇒ y =1

Hence, the value of x  and y is 1 and 1 respectively.
