Answer:

-x = 12

Step-by-step explanation:

x = -12

Answer:

12

Step-by-step explanation:

So what we know is that x is equal to negative 12. To make this easier you can say that -x is the same as -1 times x like shown below,

-1 × x  is the same as -X

We can replace the x with -12 and a negative times a negative is a positive so the answer would be 12.

If you want me to explain it more let me know, but hopefully this helps and have a great day!

The mean of six numbers is 25. Three of the numbers are 15, 15, and 30. The second unknown number is twice the first unknown num
svlad2 [7]

Answer:

The first unknown number is 10 the second is 20 and the third is 60

Step-by-step explanation

Since there is six numbers you have to multiply 25 times 6 = 150

Then 15+15+30=60

150-60= 90

10+20=30

30 times 2 equals 60

30+60=90

90+60= 150

150 divided by 6 = 25

Which set of numbers may represent the lengths of the sides of a triangle? (A) {2,5,9} (B) {6,6,7} (C) {6,4,2} (D) {7,8,1}
Olin [163]

Answer:

B {6, 6, 7}

Step-by-step explanation:

Which set of numbers may represent the lengths of the sides of a triangle? (A) {2,5,9} (B) {6,6,7} (C) {6,4,2} (D) {7,8,1}

For a given triangle with 3 sides, the sun of the length of any two sides must be greater Than the third side. This can be expressed mathematically as;

Let the side be ;

x, y and z

Then:

x > (y + z) or

y > (x + z) or

z > (x + y)

For A{2,5,9}

(2 + 5) < 9 (does not meet criteria)

For B {6,6,7}

(6 +6) > 7

(7 +6) > 6

Meets all criteria

For C {6,4,2}

(4 +2) is not greater Than 6 (does not meet criteria)

For D {7,8,1}

(7 +1) is not greater Than 8 ( does not meet criteria)
