Three times a number, less twice the number and 9 is 17. What is the number?

1 answer:

7 0

I believe your answer is 8.

Three times a number less than twice the number and nine is seventeen can be written as: 3n - 2n + 9 = 17

Solve for n as follows:

3n - 2n = n

n + 9 = 17

17 - 9 = 8

Hope this helps! :)

Answer:

$Q M \cong R M \Rightarrow$ definition of midpoint

$\overline{P M} \cong \overline{P M} \Rightarrow$ Reflexive property of congruence

$\Delta P Q M \cong \Delta P R M \Rightarrow$ SSS congruence postulate

$\angle Q \cong \angle R \Rightarrow$ CPCTC theorem

Step-by-step explanation:

Step 1: Since, M is the midpoint of the line segment QR.

$\overline{Q M} \cong \overline{R M} \Rightarrow$ definition of midpoint

Step 2: The reflexive property of congruence states that a line segment or an angle or a shape is always equal to itself.

$\overline{P M} \cong \overline{P M} \Rightarrow$ Reflexive property of congruence.

Step 3: The SSS congruence postulate states that if three sides of a triangle are equal to three sides of another triangle, then the two triangles are congruent.

$\Delta P Q M \cong \Delta P R M \Rightarrow$ SSS congruence postulate

Step 4: CPCTC theorem states if two triangles are congruent then the sides and angles are also congruent.

$\angle Q \cong \angle R \Rightarrow$ CPCTC theorem.

55) A dilation of scale factor of 4 will produce a congruent figure<br>True or False

vivado [14]

Answer:

False

Step-by-step explanation:

When a figure is dilated by a scale factor of 4, the new figure produced will be 4 times the size of the original figure. This means that, the size would change while the shape remains the same as the original figure.

Congruent figures must have the same shape and size.

Therefore, the figure produced when a dilation of scale factor of 4 is done is not a congruent figure. Rather, it is a similar figure.

So, get statement is FALSE.

A house was purchased for $89,000. After 6 years the value of the house was $101,000. Find a linear equation that models the val

mamaluj [8]

Answer: y = 2000x + 89000

Step-by-step explanation:

Given that;

initial purchase amount = $89,000

price after 6 years = $ 101,000

years = 6

now

slope = ( 101000 - 89000) / 6

slope = 12000 / 6

slope = 2000

therefore the linear equation that models the value of the house after x years will be;

y = 2000x + 89000
