Answer:

m = 3 1/3

Step-by-step explanation:

since the triangles are similar then ΔATR must be isosceles also

we can set up this proportion:

AR/TR = EF/EG

12/8 = 5/m

cross-multiply to get:

12m = 40

m = 40/12 or 20/6 which is 3 1/3

Answer:

3 1/3

Step-by-step explanation:

As both are similar, sides are in same proportion.

So, AR : EF = 12 : 5 = 2.4

=> TR : GF = 8 : m = 2.4

=> m = 8/2.4 = 10/3 = 3 1/3

Here order matters so 9P2 = 72

d. How many ways are there to place seven distinct pieces of art in a row?

Here we use permutations because distinct pieces so order matters.

7! ways

e. How many ways are there to randomly select four balls without replacement from a container of 15 balls numbered 1 to 15?

Without replacement we have to use combinations

15C4 = 1365

All reals is the answer.

Since y =-9 graph is way below the absolute value graph. Meaning that y value of modulus is greater than the constant graph.

What is the answer to 20x+4=10x+100?
Lunna [17]

first since we have the variable "x" on both sides of the equation, we can subtract the lower number to make sure x is only on one side (subtract 10x from both sides)

20x + 4 = 10x + 100

10x + 4 =100

now we can subtract 4 from both sides

10x = 96

now we can divide both sides by 10 to isolate x

x = 9.6

hope this helped
