$\qquad\qquad\huge\underline{{\sf Answer}}$

As we know, Sum of all three Angles of Triangle is equal to 180° [ by Angle sum property of triangle ]

So, the required expression is :

$\qquad \tt \dashrightarrow \:5y + 2y + 2y = 180$

$\qquad \tt \dashrightarrow \:9y = 180$

if you solve for y, you will get y = 20°

And the angles as 100°, 40° and 40°

Answer:

Step-by-step explanation:

The 3 angles add up to 180 degrees

2y + 2y + 5y = 180

9y = 180

How to solve 2y(3y+17)=12

Nataly [62]

Distribute 2y to both 3y and 17
• 6y+34= 12
then you subtract 34 on both sides and get:
• 6y=-22
Finally you divide 6y on both sides and end up with:
y= -11/3 as a fraction

47. Forming a Committee Four members from a 20-person committee are to be selected randomly to serve as chair- person, vice-chai

Svetllana [295]

Answer:

116,280 different leadership structures are possible

Step-by-step explanation:

The order is important.

For example, a Committee of John, Elisa, Laura and Rose means that John is the chairperson, Elisa the vice-chairperson, Laura the secretary and Rose the treasurer. If we exchange John and Elisa, their roles are also exchanged. This means that we use the permutations formula to solve this question.

Permutations formula:

The number of possible permutations of x elements from a set of n elements is given by the following formula:

$P_{(n,x)} = \frac{n!}{(n-x)!}$

How many different leadership structures are possible

Permutations of 4 elements from a set of 20. So

$P_{(20,4)} = \frac{20!}{(20-4)!} = 116280$

116,280 different leadership structures are possible

Y-intercept = (0, 2)<br> slope = -3/7 what is the equation?

Marianna [84]

Answer:

y = -(3/7)x + 2

Step-by-step explanation:

(see attached)

recall that the slope-intercept form of a linear equation is

y = mx + b

where m = slope = given as -(3/7)

and b = y-intercept = 2

substituting these values into the eqation:

y = mx + b

y = -(3/7)x + 2

When a number is divided by -3, the result is 12 more than the number. What is the number?

otez555 [7]

Answer:

x = -9

Step-by-step explanation:

let the number = x

So x ÷ -3 = x + 12

Mulitply both sides by -3: x = -3x -36

Add 3x to both sides: 4x = -36

Divide both sides by 4: x = -9
