What is the answer to 6x–2x+8=20

Mathematics
1 answer:
11111nata11111 [884]3 years ago
5 0

Answer:

x = 3

Step-by-step explanation:

First, simplify by subtracting 2x from 6x:

6x - 2x + 8 = 20

4x + 8 = 20

Then, solve for x:

4x + 8 = 20

4x = 12

x = 3

So, the answer is x = 3

A red die, a blue die, and a yellow die (all six sided) are rolled. we are interested in the probability that the number appeari
NISA [10]

5/54 or approximately 0.092592593  
There are 6^3 = 216 possible outcomes of rolling these 3 dice. Let's count the number of possible rolls that meet the criteria b < y < r, manually.
 r = 1 or 2 is obviously impossible. So let's look at r = 3 through 6.
 r = 3, y = 2, b = 1 is the only possibility for r=3. So n = 1
 r = 4, y = 3, b = {1,2}, so n = 1 + 2 = 3
 r = 4, y = 2, b = 1, so n = 3 + 1 = 4
 r = 5, y = 4, b = {1,2,3}, so n = 4 + 3 = 7
 r = 5, y = 3, b = {1,2}, so n = 7 + 2 = 9
 r = 5, y = 2, b = 1, so n = 9 + 1 = 10
 
 And I see a pattern, for the most restrictive r, there is 1 possibility. For the next most restrictive, there's 2+1 = 3 possibilities. Then the next one is 3+2+1
= 6 possibilities. So for r = 6, there should be 4+3+2+1 = 10 possibilities.
Let's see
 r = 6, y = 5, b = {4,3,2,1}, so n = 10 + 4 = 14
 r = 6, y = 4, b = {3,2,1}, so n = 14 + 3 = 17
 r = 6, y = 3, b = {2,1}, so n = 17 + 2 = 19
 r = 6, y = 2, b = 1, so n = 19 + 1 = 20 
 And the pattern holds. So there are 20 possible rolls that meet the desired criteria out of 216 possible rolls. So 20/216 = 5/54.

Examine the diagram. A triangle has angles A, 15 degrees, 80 degrees. The exterior angle to angle A is B. What is the sum of the
QveST [7]

Answer:

m<A = 30degrees

m<B = 70degrees

Step-by-step explanation:

Find the diagram attached

From the diagram;

m<A + 150 = 180

m<A = 180 - 150

m<A = 30degrees

Also since the sum of angles in a triangle is 180degrees, hence;

m<B+m<A + 80 = 180

m<B+30+80 = 180

m<B+110 = 180

m<B = 180 - 110

m<B = 70degrees
