The sum of three numbers is 855. One of the numbers, x, is 50% more than the sum of the other two numbers. What is the value of
Snowcat [4.5K]

Answer:

The value of x = 513

Step-by-step explanation:

Let x, y, and z be the three numbers

Given

x+y+z=855

Assuming x be the number which is 50% more than the sum of the other two numbers.

i.e.

(150)% of (y+z) = 1.5(y+z)

                y + z = x/1.5

As we know that

x + y + z = 855

substituting y + z = x / 1.5 in the equation

x+\frac{x}{1.5}=855

Multiply both sides by 1.5

x\cdot \:1.5+\frac{x}{1.5}\cdot \:1.5=855\cdot \:1.5

1.5x+x=1282.5

2.5x=1282.5

Divide both sides by 2.5

\frac{2.5x}{2.5}=\frac{1282.5}{2.5}

x = 513

Therefore, the value of x = 513

Line g passes through points (1, 1) and (10,9). Line h is perpendicular to g. What is the
shusha [124]

Answer:

-9/8

Step-by-step explanation:

Slope m = (y2-y1)/(x2-x1)

using (1,1) and (10,9)

m = (9 - 1)/(10 - 1)

m = (8)/(9)

m = 8/9

slope of line g is 8/9

Perpendicular lines have slopes that are negative reciprocals of one another

so slope of h is -9/8

Which value of k will make this relationship NOT a function? {(−7, 2), (−1, 0), (4, 8), (k, 0)} ​
ruslelena [56]

Answer:

In this example, if k = -7, this relationship is not a function, since x = -7 would have both y = 2 and y = 0.

Step-by-step explanation:

Requirement to be a function:

For a relationship to be a function, all values of x must have only one corresponding value of y.

In this question:

For x = -7, y = 2

For x = -1, y = 0

For x = 4, y = 0

For x = k, y = 0

A value of x must not have more than 1 value of y.

In this example, if k = -7, this relationship is not a function, since x = -7 would have both y = 2 and y = 0.
