12. The second of three numbers is one less than the first. The third
number is 5 less than twice the second. If the third number exceeds the
first number by 12, find the three
numbers.

Answers

Answer 1

Answer:

The three numbers are 19, 18, and 31.

Step-by-step explanation:

The three numbers are x, y, and z.

y=x-1

z=2y-5

z=x+12

2y-5=x+12

2(x-1)-5=x+12

2x-2-5=x+12

x=19

y=18

z=31

Answer 2

The three numbers are 19, 18 and 31

what is Algebra?

Algebra is the branch of mathematics that helps in the representation of problems or situations in the form of mathematical expressions.

let the three numbers be x, y, and z.

So, according to question

The second of three numbers is one less than the first,

y = x-1

The third number is 5 less than twice the second,

z=2y-5

also, If the third number exceeds the first number by

12z=x+12

Now, equating the equations

2y-5=x+12

2(x-1)-5=x+12

2x-2-5=x+12

x=19

So, y=18 and z=31.

Answer:

[tex]B=\frac{2A}{h}-b[/tex]

Step-by-step explanation:

To solve this B needs to be isolated. First we must multiply both sides of the equation by 2 to get rid of the fraction on the left side. Next, divide both sides by h to get rid of the h on the left side. Finally, subtract b form both sides to get B by itself.

your answer would be b=2a/h-B

Which angles form a linear pair?

Answers

Answer:

A common arm

A common vertex

Their interiors do not overlap

The sum of two angles is 180°.

Therefore, linear pair of angles are adjacent angles whose non-common arms are opposite rays.

Explanation: A linear pair of angles is formed when two lines intersect. Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.

We can put these into the 2-point form of the equation for a line:

The discriminant of a quadartic equation is 40. What is the nature of the solutions?

Answers

Since the discriminant is positive, this means we have two distinct real solutions.

If a, b, and c are rational numbers, then a discriminant of D = 40 indicates the two solutions are not rational. We would need D to be a perfect square to get two rational solutions.

The nature of the solution of positive discriminant of a quadratic equation shows two distinct real number solutions.

Here discriminant of a quadratic equation is 40.

What is discriminant?

The discriminant is the part of the quadratic formula underneath the square root symbol; [tex]b^{2} -4ac[/tex]. The discriminant tell us whether there are two solution, one solution, or no solutions.

Now, since the discriminant is given as 40 that's mean discriminant is positive.

Hence we have two distinct real number solutions.
