Answer:

The answer to your question is  x² + 5/2x - 3/2 = 0

Step-by-step explanation:

Data

Quadratic equation           x² + 2.5x - 1.5 = 0

Process

1.- Convert the decimals into fractions

2.5 = 25/10 = 5/2

1.5 = 15/10 = 3/2

2.- Substitution

Find the value of two numbers is their sum is 21 and their difference is 3
kobusy [5.1K]

Hello from MrBillDoesMath

Answer:   12, 9

Discussion:

Let x be the first number and y the second number. The form the problem statement:

x + y = 21

x - y = 3


Add the two equations. This gives:

(x + x ) + ( y-y) = 21 + 3 =>

2x + 0 = 24 =>

x = 12

Since x -y =3, substituting in the value of x gives,  12 - y = 3 so y = 9


Thank you,

Mr. B

Answer: Correct Answer is 4th option , 28


Step-by-step explanation:


We can find the measure of the angle using the tangent.


We know, tangent of an angle = Perpendicular/Base, corresponding to that angle.


So, Tan of angle T = RG / RT

or, Tan of angle T = 8/15

or, angle T = tan inverese of 8/15

or, angle T = 28.07


So, angle T rounded to nearest degree = 28


Hope this helps.


Thank you.
