The sum of three numbers is 100. The second number is 2 times the third. The third number is 8 less than the first. What are the

8_murik_8 [283]

Answer:

Step-by-step explanation:x+y+z=100(let x ,y,z represent the first second and third numbers respectively)

Therefore,y=2z

z=x-8

y=2x-16

substituting the values of x,y and z into the question,we have

x+(2x-16)+(x-8)=100

Simplifying,we have

4x-24=100

adding 24 to both sides of the equation,

4x=100+24

4x=124

dividing both sides of the equation by the co-efficient of x,we have

4x/4=124/4

4.31=124

therefore,x=31.

What's absolute value |-8|

maks197457 [2]

The absolute value of a number can never be negative. That's because it represents the distance of a number from zero on a number line. The number $-8$ is $8$ digits to the left of zero on a number line. So, the absolute value of $-8$ would be $8$ .

Let me know if you have any questions regarding this problem!
Thanks!

Answer:

x = 13

y = 15

Step-by-step explanation:

ST = DT ( Reason : from given )

5x = 65

x = 65 / 5

x = 13

TY = TU ( Reason : from given )

3y + 5 = 50

3y = 50 - 5

3y = 45

y = 45 / 3

y = 15

Consider the line y=4x-4.

Answer:

parallel: y = 4x -6
perpendicular: y = -1/4x +27/4

Step-by-step explanation:

If we want the new line to be written in slope-intercept form, we need to find the new value of the y-intercept. The equation of the line is ...

y = mx +b . . . . . . . for slope m and y-intercept b

Solving for b gives ...

b = y -mx . . . . . . . subtract mx from both sides.

The values of x and y come from the point we want the line to pass through. The value of m will be the same for the parallel line as for the given line: 4. For the perpendicular line, it will be the opposite reciprocal of this: -1/4.

<u>Parallel line</u>

b = 6 -4(3) = 6 -12 = -6

y = 4x -6

Perpendicular line

b = 6 -(-1/4)(3) = 6 +3/4 = 27/4

y = -1/4x +27/4

If standard deviation of a given data is 5 and mean is 50 then coefficient of variation (C.V) is equal to *

torisob [31]

Answer:

Step-by-step explanation:

Coefficient of variation is a measure of dispersion, showing the variability of data in relation to the mean.

The Coefficient of variation compares the degree of variation between data points. The coefficient of variation is the ratio of mean to standard deviation. It is given by the formula:

Coefficient of variation = mean / standard deviation

Coefficient of variation = 50 / 5

Coefficient of variation = 10
