Aleksandr [31]

Answer:

3x + 2 = 50

16

Step-by-step explanation:

According to the given situation, the equation to determine the number of friends is shown below:-

We assume the number of friends is x

50 - 3x = 2

-3x = -48

3x = 48

x = 16

So, the equation is

3x + 2 = 50

and the number of friends is 16

Therefore, the equation to determine the number of friends we just solved the above equation.

What is the value of x?
Sauron [17]

Answer:

85°

Step-by-step explanation:

The triangle pictured is an isosceles triangle because side KJ = LJ.

this means that ∠JKL = ∠JLK = x°

Also recall that all interior angles of a triangle add up to 180°

Hence,

180° =  ∠JKL + ∠JLK + ∠KJL

180 =  x + x + 10

180 = 2x + 10  (subtract 10 from both sides and rearrange)

2x = 180 - 10

2x = 170 (divide both sides by 2)

x = 170 / 2 = 85°

Using prime factorization what is the GCF 3y 2 squared, 24y 3 cubed
WINSTONCH [101]

Answer:

3y^2

Step-by-step explanation:

Given:

To find the GCF of 3y^2\ and\ 24y^3 using prime factorization.

Writing each in prime factors:

3 = 1 \times <u>3</u>

24 = 1 \times 2 \times 2 \times2 \times <u>3</u>

Now, GCF of 3 and 24 is 3

y^2=1\times y\times y

y^3=1\times y\times y\times y

GCF of y^2 and y^3 is y\times y=y^2.

Therefore, the overall GCF of the two terms is 3y^2
