Sixteen diminished by 8 times a number is the same as 5 diminished by 9 times the number. find the number.

shutvik [7]

16-8n=5-9n add 9n to both sides

16+n=5 subtract 16 from both sides

n=-11

check...

16-(8*-11)=5-(9*-11)

16-(-88)=5-(-99)

16+88=5+99

In the diagram below, DE is parallel to XY. What is the value of x?

Vaselesa [24]

Answer:

the value of x is

115°+y=180 (being linear pair)

y =180°-115°

therefore, the value of y is 65°.

now again x=y=65°(being corresponding angle)

so, the value of x is 65°.

(2.2.5) In horse racing, one can make a trifecta bet by specifying which horse will come in first, which will come in second, an

DaniilM [7]

Answer:

56 ways.

Step-by-step explanation:

This question is solved by using combinations and permutations chapters in the math book.

To put it simply, we need to find the number of 3 horse combinations we can make from 8 horses. This requires the combinations formula:

$C(n,r)=\frac{n!}{r!(n-r)!}$

here n is the total number of objects to choose from, and r is the number of objects we require in the combination or group.

Since there are 8 horses, n= 8

Since we need to choose only 3 of them, and order does not matter, r= 3

Solving the equation above using these inputs gives us 56 unique ways we can choose the three winners.
