(5x - 17) + (3x - 11)= 180 [ Linear Pair ]
= 8x - 28= 180
= 8x= 208
= x = 208/8
= x = 26

3x-11
= 3*26 - 11
=67

Now, we have:
(2y+5)+90+(3x-11)=180 [Linear Pair]

Substituting (3x-11),
(2y+5) + 90 + 67= 180
= (2y+5)+157= 180
= 2y + 162= 180
= 2y= 18
=y = 18/2
=y= 9

Therefore, x= 26, and y= 9

Have a great day.

The perimeter of the triangular park on the right is 16x-6. What is the missing length? The bottom side length is 5x+4 and the r
Romashka-Z-Leto [24]

Answer:

(9x-5)\ units

Step-by-step explanation:

<u><em>The picture of the question in the attached figure</em></u>

we know that

The perimeter of a triangle is the sum of the length of their three  sides

so

P=a+b+c

where

a,b,c are the length sides of the triangle

In this problem we have

P=(16x-6)\ units\\a=(2x-5)\ units\\b=(5x+4)\ units

substitute and solve for the missing length

(16x-6)=(2x-5)+(5x+4)+c\\c=(16x-6)-(2x-5)-(5x+4)\\c=(9x-5)\ units

Suppose the average math SAT score for students enrolled at local community college is 490.4 with a standard deviation of 63.7.
lakkis [162]

Answer:

Option B) 9.1      

Step-by-step explanation:

We are given the following in the question:

Average score = 490.4

Standard deviation = 63.7

Sample size, n = 49

Formula:

=\dfrac{\sigma}{\sqrt{n}}

Putting values, we get,

Standard error =

=\dfrac{\sigma}{\sqrt{n}} = \dfrac{63.7}{\sqrt{49}} = 9.1

Thus, the correct answer is

Option B) 9.1

a mug is 2/7 full. The mug contains 1/3 of a cup of water. Find the capacity of the mug. Write the answer as a fraction or mixed
Ahat [919]

Answer:

7/6 cups

Step-by-step explanation:

Given the following information :

Mug is 2/7 full

Amount of water in the mug = 1/3 cup

Assume the full capacity of the mug = m

Then the current capacity of water in mug = (2/7) of m = (2/7)m

Current capacity of water in mug is equivalent to 1/3 cup of water

Hence,

(2/7)m = 1/3

2m/7 = 1/3

Cross multiply

(2m * 3) = 7 * 1

6m = 7

m = 7/6

m = 1 1/6 cups
