Answer:

$x=24$

Step-by-step explanation:

Angles in a straight line add up to 180°

$4x+9+2x+27=180$

$x=24$

Answer:

x = 24°

Step-by-step explanation:

To find 'x', the Alternate Exterior angle postulate will need to be used.

'4x + 9' and '2x + 27' are alternate exterior angles. Therefore, they must sum up to 180.

180 = 4x + 9 + 2x + 27

Combine like terms:

180 = 6x + 36

144 = 6x

x = 24°

The average of five distinct scores has the same value as the median of the five scores. The sum of the five scores is 420. What

givi [52]

Answer:

The sum of five scores that is not the median is, 336

Step-by-step explanation:

Average defined as the the sum of the observation to the total number of the observation.

Given: The sum of the five scores is 420

Then, by definition of average;

Average of five distinct score = $\frac{420}{5} = 84$

It is also, given that the average of five distinct scores has the same value as the median of the five scores.

⇒Median of five scores = 84

Since, scores are distinct, therefore

Sum of all scores that is not the median = Sum of five scores - median = 420-84 = 336

therefore, the sum of five scores that is not the median is, 336

Please help very urgent on test...

stepladder [879]

Answer:

Equation: (2x+5)4=(2x+8)3

X: 2

Perimeter: 36

Step-by-step explanation:

You would multiply 2x+5 and 4 because there are four sides to a square, so the perimeter of the square would be 8x+20. This would go same for the triangle, making the perimeter 6x+24.

So 8x+20=6x+24 is your new equation. Then, you do the opposite of the order of operations, and add or subtract first. It would be easiest to subtract 20 and 6x from both sides.

That leaves you with 2x=4. Dividing 2 by both sides means x=2

You can plug this in to prove if it is correct.

16+20=36

12+24=36
