Answer:

n = -2

Step-by-step explanation:

5n - 16 - 8n = -10

Combine like terms

-3n -16 = -10

Add 16 to each side

-3n-16+16 = -10+16

-3n = 6

Divide by -3

-3n/-3 = 6/-3

n = -2

<u>Solu</u><u>tion</u><u> </u><u>:</u><u>-</u>

=> 5n - 16 - 8n = -10 .

=> 5n - 8n - 16 = -10.

=> -3 n = 16 - 10.

=> - 3n = 6 .

=> n = 6 / -3 .

=> n = -2 .

Suppose you have 13 tubes of paint. How many distinct color groupings can you make with your paint?
anzhelika [568]

Answer:

32767 distinct color grouping

Step-by-step explanation:

Given data:

Total tube is 13

for distinct color, group can be 1,2,3,4,.... 15

For total number of ways we have following relation

^nC_0 +^nC_1 +^nC_2 + .......^nC_n = 2^n

here n = 13 so we have

^15C_0 +^15C_1 +^15C_2 + .......^15C_{15} = 2^15

for at least one

= 2^{15} - 1

= 32768 -1

= 32767 distinct color grouping

Determine whether the following conjecture is true or false. Give a counterexample if the answer is false.
brilliants [131]
This conjecture is false, A and C don't have to be complementary angles.

Let Angle A be 100 and Angle B be 80 degrees. They are supplementary (sum of 180).
Let Angle C be 100 and Angle B is still 80 degrees. They are supplementary.

However, Angle A and Angle C are not complementary (sum of 90).

Please help thx a bunch
kirza4 [7]
A.
2/3A=-24
time both sides by 3/2
A=-72/2
A=-36

B.
20=-B/0.2
times both sides by 0.2
4=-B
times -1
-4=B


distance between 2 points x and y is |x-y|

so
distance between A and B is distance between -4 and -72 or
|-72-(-4)|=|-72+4|=|-68|=68
the distance is 68
